The North Korean hacking group known as Lazarus is exploiting the Log4J remote code execution vulnerability to inject backdoors that fetch information-stealing payloads on VMware Horizon servers. According to a report published by analysts at Ahnlab's ASEC, Lazarus has been targeting vulnerable VMware products via Log4Shell since April 2022.
VMware has released patches for a privately reported critical vulnerability in VMware's Workspace ONE Access, VMware Identity Manager, vRealize Lifecycle Manager, vRealize Automation, and VMware Cloud Foundation products, and is urging administrators to patch or mitigate immediately, because "The ramifications of this vulnerability are serious." Simultaneously, the Cybersecurity and Infrastructure Security Agency has issued an emergency directive for all federal civilian executive branch agencies, which are ordered to enumerate all instances of affected VMware products and either deploy the updates provided by VMware or remove those instances from agency networks by May 23.
Uncle Sam's Cybersecurity and Infrastructure Security Agency has issued two warnings in a single day to VMware users, as it believes the virtualization giant's products can be exploited by miscreants to gain control of systems. The agency rates this threat as sufficiently serious to demand US government agencies pull the plug on their VMware products if patches can't be applied.
VMware has issued patches to contain two security flaws impacting Workspace ONE Access, Identity Manager, and vRealize Automation that could be exploited to backdoor enterprise networks. The first of the two flaws, tracked as CVE-2022-22972, concerns an authentication bypass that could enable an actor with network access to the UI to gain administrative access without prior authentication.
The Department of Homeland Security's cybersecurity unit ordered Federal Civilian Executive Branch agencies today to urgently update or remove VMware products from their networks by Monday due to an increased risk of attacks. In April, VMware patched another set of critical vulnerabilities, a remote code execution bug and a 'root' privilege escalation in VMware Workspace ONE Access and VMware Identity Manager.
VMware warned customers today to immediately patch a critical authentication bypass vulnerability "Affecting local domain users" in multiple products that can be exploited to obtain admin privileges."This critical vulnerability should be patched or mitigated immediately per the instructions in VMSA-2021-0014," VMware warned on Wednesday.
Recently reported VMware bugs are being used by hackers who are focused on using them to deliver Mirai denial-of-service malware and exploit the Log4Shell vulnerability. Security researchers at Barracuda discovered that attempts were made to exploit the recent vulnerabilities CVE-2022-22954 and CVE-2022-22960, both reported last month.
The Cybersecurity and Infrastructure Security Agency has added two more vulnerabilities to its list of actively exploited bugs, a code injection bug in the Spring Cloud Gateway library and a command injection flaw in Zyxel firmware for business firewalls and VPN devices. Threat actors are also abusing a critical Zyxel firmware vulnerability, patched on May 12th and under active exploitation starting the next day, on May 13th. Rapid7 found over 15,000 vulnerable Zyxel products exposed to Internet access, while the Shadowserver Foundation spotted at least 20,000 potentially impacted devices.
A team of Iranian cyber-spies dubbed Rocket Kitten, for one, is likely behind attempts to exploit a critical remote-code execution vulnerability in VMware's identity management software, according to endpoint security firm Morphisec. VMware patched its flawed software on April 6, and attackers were not far behind.
Advanced hackers are actively exploiting a critical remote code execution vulnerability, CVE-2022-22954, that affects in VMware Workspace ONE Access.The issue was addressed in a security update 20 days ago along with two more RCEs - CVE-2022-22957 and CVE-2022-22958 that also affect VMware Identity Manager, VMware vRealize Automation, VMware Cloud Foundation, and vRealize Suite Lifecycle Manager.
