    OpenSSL AVX512 Bug

    There’s a bug in OpenSSL 3.0.4, and may be a particularly nasty one, but it only occurs on CPUs with the AVX512 extensions. The problem is triggered in ossl_rsaz_mod_exp_avx512_x2(), which makes a call off to bn_reduce_once_in_place(). The call includes the value factor_size, which is supposed to be the number of words to process, but the old code was instead sending the bit size. This worked most of the time, but in certain cases, resulted in a heap buffer overflow. The spooky part of this is that it can be triggered by a TLS handshake, and other potentially attacker-controlled inputs. The only thing lacking to call this a 10.0 CVSS CVE is an actual demonstration of exploitation. As it is, it’s easy to demonstrate a crash. A 3.0.5 release will be made soon, containing the fix, but it’s unclear when that will happen. Most distros seem to be delaying shipping the 3.0.4 release, waiting for the fix for this potentially serious issue

    Cerby Emerges From Stealth With Security Platform for Unmanageable Apps
    https://www.securityweek.com/cerby-emerges-stealth-security-platform-unmanageable-apps

    California-based company Cerby on Monday announced that it has emerged from stealth mode with a security platform for unmanageable applications, as well as $12 million in seed funding.

    Cerby aims to provide a solution that creates a balance between allowing employees to use the applications they need to do their job and the enterprise being able to address shadow IT risks and secure its systems.

    The company has commissioned a survey of 500 business professionals in North America and the UK. The study found that a vast majority of respondents want to have full control over the applications they use for work-related purposes, and 51% said they have continued using preferred applications even after they were specifically banned by their employer.

    Cerby wants to address this problem with a platform that can help organizations secure their systems while enabling employees to use the applications they need.

    Employees can register their own applications and the platform helps ensure they are securely configured and that they don’t violate any security policies.

    Oracle patches ‘miracle exploit’ impacting Middleware Fusion, cloud services
    https://portswigger.net/daily-swig/oracle-patches-miracle-exploit-impacting-middleware-fusion-cloud-services

    Researchers describe discovery of ‘mega’ zero-day

    Oracle has patched a remote code execution (RCE) vulnerability impacting Oracle Fusion Middleware and various other Oracle systems.

    Security researchers ‘Peterjson’ and ‘Jang’ reported a pair of severe flaws to Oracle that can be chained to achieve RCE, which they dubbed the ‘Miracle Exploit’.

    The researchers said they privately told Oracle about a serious vulnerability they discovered in Oracle Access Manager, tracked as CVE-2021–35587. The CVSS 9.8 bug is described as an “easily exploitable” flaw that allows unauthenticated attackers with network access via HTTP for application takeover.

    Jang said the flaw was discovered by accident when the duo were “building a PoC [proof of concept exploit code] for another mega 0-day”.

    While working with the Zero Day Initiative (ZDI), this research led to the discovery of CVE-2022–21445. This ‘mega’ bug, issued a severity score of 9.8, was found in the Oracle Application Development Framework (ADF) Faces architecture, a component of Oracle Fusion Middleware.

    The deserialization of trusted data issue can be chained with CVE-2022–21497 (CVSS 8.1), a takeover flaw in Oracle Web Services Manager, to achieve pre-authentication RCE.

    CVE-2022–21445 impacts a variety of products and services based on Fusion Middleware, various Oracle systems, and even Oracle’s cloud infrastructure. Unauthenticated attackers with network access, via HTTP, can abuse the vulnerability chain.

    “One more thing to note, any website was developed by ADF Faces framework are affected,” Peterjson said.

    After testing Oracle services and domains, the vulnerability report was submitted to the vendor on October 25, 2021. In the same month, Oracle confirmed receipt of the report and said it was investigating. However, it took the best part of six months for a patch to be issued.

    Both issues have been resolved in Oracle’s April round of patches.

    Companies utilizing vulnerable Oracle software are urged to apply the patch immediately.

    Peterjson told The Stack that companies have been informed if they have not applied Oracle’s fix, and that he believes the number of exposed instances is “huge”.

    “Why [did] we hack some Oracle’s sites? Because we want to demonstrate the impact to Oracle and let them know this vulnerability is super dangerous, it affects Oracle system[s] and Oracle’s customers,” Peterjson commented.

    “That’s why we want Oracle take an action ASAP. But as you can see, 6 months for Oracle to patch it, I don’t know why, but we have to accept it and follow Oracle’s policy.”

    Oracle vuln left scores of blue chips exposed to pre-auth RCE exploit for 6 MONTHS post disclosure
    https://thestack.technology/oracle-middleware-vulnerability-blue-chips-exposed-6-months/

    A critical Oracle Fusion Middleware vulnerability, that sat unpatched for six months after disclosure, exposed companies including Starbucks, BestBuy and Dell to potential pre-auth RCE attacks, said the finders of the Oracle exploit.

    The Oracle exploit was found and reported by security researchers “peterjson” and “Jang” in October 2021. But the Oracle middleware vulnerability, which they named “Miracle”, did not receive a patch until April 2022 under Oracle’s often-overlooked patch cycle. The two have now posted further details about the vulnerability, allocated CVE-2022–21445 with a critical CVSS score of 9.8 and urged rapid patching.

    The two, working from Vietnam under the Zero Day Initiative (ZDI) bug bounty programme, said they also popped login.oracle.com “which is play [sic] an important role in oracle’s online services” in a bid to emphasise the severity of the flaw after Oracle took longer than they had expected to patch the vulnerability.

    The Miracle exploit is enabled by an ADF Faces vulnerability (CVE-2022–21445), and an Oracle Web Services Manager flaw (CVE-2022–21497, rated 8.1). Both Oracle middleware vulnerability patches are covered by the vendor’s April 2022 critical patch update.

    “After [we] disclosed this bug with Oracle, Oracle took almost 6 months to patch this vulnerability in each product inside Oracle Fusion Middleware. We also reported pre-auth RCEs to BestBuy, Starbucks, USAA, NAB Group, Regions Bank, Dell, … via their bug bounty program after the patch was released,” said the researchers’ post.

    Any unauthenticated attacker with network access via HTTP can abuse the vulnerability.

    He declined to give a hard number for total potentially exposed instances but said “we believe it’s huge” as the vulnerability in theory affects Oracle online services, Oracle Cloud Infrastructure and on-prem instances.

    Any product which uses ADF Faces becomes vulnerable to attack, and the researchers were able to use the Oracle exploit to get at least some access to products including Business Intelligence, Enterprise Manager, Identity Management, SOA Suite, WebCentre Portal, Application Testing Suite and Transportation Management.

    But for Oracle Access Manager (OAM), they found two ways to achieve pre-auth RCE: “We want to focus on this because OAM plays an important role on each company infrastructure. Also, many Oracle’s online services / cloud services run OAM as SSO service for users” — detailing the technical attack chain here.

    In a separate post on a different but related Oracle middleware vulnerability, Jang listed users of OAM as including Huawei, VMware and Qualcomm

    By combining the ADF Faces deserialization vulnerability with a flaw in the Oracle Web Services Manager, the researchers were able to gain access to Oracle servers. These included edelivery.oracle.com , businessnetwork.oracle.com – as well as login.oracle.com.

    “Why we hack some Oracle’s sites? Because we want to demonstrate the impact to Oracle and let them know this vulnerability is super dangerous , it affects Oracle system and Oracle’s customers. That’s why we want Oracle take an action ASAP. But as you can see, 6 months for Oracle to patch it, I don’t know why, but we have to accept it and follow Oracle’s policy,” said peterjson in the blog post.

    The reserchers’ blog post contains a very detailed explanation of how they uncovered the Oracle middleware vulnerability, which is worth a read – and given it exists, the time is ripe to patch the Oracle exploit as fast as possible.

    Miracle – One Vulnerability To Rule Them All
    https://peterjson.medium.com/miracle-one-vulnerability-to-rule-them-all-c3aed9edeea2

    # Summary

    Let us name this attack The Miracle Exploit because it affects many products based on Oracle Fusion Middleware and Oracle online systems. Miracle means Middleware Fusion with Oracle

    Firstly, we found many pre-auth RCEs which affect Oracle’s Product in Oracle Middleware Fusion and they also affect Oracle online systems, Oracle Cloud Infrastructure. After a month try to explore as much as we can and end up with multiple pre-auth RCEs in many products inside Oracle Middleware.

    One more thing to note, any website was developed by ADF Faces framework are affected. This means many Oracle’s online systems, Oracle Cloud Infrastructure are also affected!

    Cyberattack Forces Iran Steel Company to Halt Production
    https://www.securityweek.com/cyberattack-forces-iran-steel-company-halt-production

    One of Iran’s major steel companies said Monday it was forced to halt production after being hit by a cyberattack that also targeted two other plants, apparently marking one of the biggest such assaults on the country’s strategic industrial sector in recent memory.

    The Iranian government did not acknowledge the disruption or blame any specific group for the assault on the state-owned Khuzestan Steel Co. and Iran’s two other major steel producers, which constitutes just the latest example of an attack crippling the country’s services in recent months amid heightened tensions in the region.

    An anonymous hacking group claimed responsibility for the attack on social media, saying it targeted Iran’s three biggest steel companies in response to the “aggression of the Islamic Republic.”

    The group, calling itself “Gonjeshke Darande,” shared what purported to be closed-circuit footage from the Khuzestan Steel Co. factory floor that showed a piece of heavy machinery on a steel billet production line malfunction and cause a massive fire.

    “These companies are subject to international sanctions and continue their operations despite the restrictions,” the group said, citing their links to Iran’s paramilitary Revolutionary Guard.

    The LockBit 3.0 ransomware operation was launched recently and it includes a bug bounty program offering up to $1 million for vulnerabilities and various other types of information.

    LockBit has been around since 2019 and the LockBit 2.0 ransomware-as-a-service operation emerged in June 2021. It has been one of the most active ransomware operations, accounting for nearly half of all ransomware attacks in 2022, with more than 800 victims being named on the LockBit 2.0 leak website.

    The cybercriminals are encrypting files on compromised systems and also stealing potentially valuable information that they threaten to make public if the victim refuses to pay up. With the launch of LockBit 3.0, it seems they are reinvesting some of the profit in their own security via a “bug bounty program”.LockBit 3.0

    Similar to how legitimate companies reward researchers to help them improve their security, LockBit operators claim they are prepared to pay out between $1,000 and $1 million to security researchers and ethical or unethical hackers.

    CISA Says ‘PwnKit’ Linux Vulnerability Exploited in Attacks
    https://www.securityweek.com/cisa-says-pwnkit-linux-vulnerability-exploited-attacks

    The US Cybersecurity and Infrastructure Security Agency (CISA) says a Linux vulnerability tracked as CVE-2021-4034 and PwnKit has been exploited in attacks.

    The flaw, which came to light in January, affects Polkit, a component designed for controlling system-wide privileges in Unix-like operating systems. Polkit is developed by Red Hat, but it’s also used by other Linux distributions.

    PwnKit has been described as a memory corruption issue that can be exploited for privilege escalation — it allows any unprivileged local user to elevate permissions to root.

    The vulnerability has been found to impact the products of several major companies. Juniper Networks, Moxa, IBM, VMware, Siemens and others have released advisories to describe the impact of CVE-2021-4034.

    Proof-of-concept (PoC) exploits have been available and exploitation is easy, which is why experts have been warning that the likelihood of malicious exploitation is high.

    CISA on Monday added the vulnerability to its Known Exploited Vulnerabilities Catalog — also known as the agency’s “Must Patch” list — and instructed federal agencies to install patches until July 18.

    Chinese Threat Actor Targets Rare Earth Mining Companies in North America, Australia
    https://www.securityweek.com/chinese-threat-actor-targets-rare-earth-mining-companies-north-america-australia

    Mandiant’s security researchers have been tracking influence campaigns that a Chinese threat actor named Dragonbridge has been conducting against rare earth mining companies in Australia, Canada, and the United States.

    Active since at least 2019, Dragonbridge has been using a network of thousands of inauthentic accounts on social platforms, websites, and forums to promote narratives in support of China’s political interests.

    More recently, the threat actor has started a social media campaign focused on rare earth mining companies, including Lynas Rare Earths Ltd (Australia), Appia Rare Earths & Uranium Corp (Canada), and USA Rare Earth.

    As Mandiant notes, the targeted industry is of strategic significance to China, with the three victim companies challenging the country’s supply chain dominance in the industry. Rare earth metals represent a critical component of consumer and military products, including aircraft engines and missile guidance systems.

    New Database Catalogs Cloud Vulnerabilities, Security Issues
    https://www.securityweek.com/new-database-catalogs-cloud-vulnerabilities-security-issues

    Cloud security company Wiz has announced the launch of a new database whose goal is to keep track of vulnerabilities and other security issues affecting cloud services.

    Cybersecurity researchers often find vulnerabilities in widely used cloud services offered by companies such as AWS, Microsoft and Google. ​​While some cloud vulnerabilities don’t require any action from the user, there are situations where impacted customers do need to take certain steps, such as rotating keys.

    According to Wiz, there are several problems when it comes to the disclosure and handling of cloud vulnerabilities, including that there is no standardized notification channel across service providers and CVE identifiers are in many cases not assigned, which makes it more difficult to track issues. In addition, there is no severity scoring to help users prioritize vulnerabilities, and there is no transparency into the flaws and their detection.

    Wiz has been urging the community to improve the response to cloud security vulnerabilities, including by creating a public and standardized database for reporting and enumerating vulnerabilities.

    The company has now announced the launch of such a database — hosted at cloudvulndb.org — which aims to catalog all known vulnerabilities and other types of security issues affecting cloud services.
