Researchers at Trellix have discovered a critical unauthenticated remote code execution vulnerability impacting 29 models of the DrayTek Vigor series of business routers. The vulnerability is tracked as CVE-2022-32548 and carries a maximum CVSS v3 severity score of 10.0, categorizing it as critical.

The Department of Homeland Security warned that attackers could exploit critical security vulnerabilities in unpatched Emergency Alert System encoder/decoder devices to send fake emergency alerts via TV and radio networks. The warning was issued by DHS' Federal Emergency Management Agency as an advisory delivered through the Integrated Public Alert and Warning System.

Cisco on Wednesday rolled out patches to address eight security vulnerabilities, three of which could be weaponized by an unauthenticated attacker to gain remote code execution or cause a denial-of-service condition on affected devices. The most critical of the flaws impact Cisco Small Business RV160, RV260, RV340, and RV345 Series routers.

Cisco has fixed critical security vulnerabilities affecting Small Business VPN routers and enabling unauthenticated, remote attackers to execute arbitrary code or commands and trigger denial of service conditions on vulnerable devices.Successful exploitation of CVE-2022-20842 with crafted HTTP input could allow attackers "To execute arbitrary code as the root user on the underlying operating system or cause the device to reload, resulting in a DoS condition," the company explains.

VMware and experts alike are urging users to patch multiple products affected by a critical authentication bypass vulnerability that can allow an attacker to gain administrative access to a system as well as exploit other flaws. "Given the prevalence of attacks targeting VMware vulnerabilities and a forthcoming proof-of-concept, organizations need to make patching CVE-2022-31656 a priority," Claire Tillis, senior research engineer with Tenable's Security Response Team, said in an email to Threatpost.

VMware has released fixes for ten vulnerabilities, including CVE-2022-31656, an authentication bypass vulnerability affecting VMware Workspace ONE Access, Identity Manager and vRealize Automation, which the company considers critical and advises to patch or mitigate immediately.CVE-2022-31656 is an authentication bypass vulnerability affecting local domain users on VMware Workspace ONE Access, Identity Manager and vRealize Automation, that may allow an attacker with network access to the UI to obtain administrative access without the need to authenticate first.

VMware has fixed a critical authentication bypass vulnerability that hits 9.8 out of 10 on the CVSS severity scale and is present in multiple products. The critical vulnerability is similar to, or perhaps even a variant or patch bypass of, an earlier critical authentication bypass vulnerability that also rated 9.8 in severity and VMware fixed back in May. Shortly after that update was issued, CISA demanded US government agencies pull the plug on affected VMware products if patches can't be applied.

VMware has warned admins today to patch a critical authentication bypass security flaw affecting local domain users in multiple products and enabling unauthenticated attackers to gain admin privileges. "This critical vulnerability should be patched or mitigated immediately per the instructions in VMSA," VMware warned.

CISA has added a critical Confluence vulnerability tracked as CVE-2022-26138 to its list of bugs abused in the wild, a flaw that can provide remote attackers with hardcoded credentials following successful exploitation. Today, CISA added the CVE-2022-26138 to its catalog of Known Exploited Vulnerabilities based on evidence of active exploitation.

A week after Atlassian rolled out patches to contain a critical flaw in its Questions For Confluence app for Confluence Server and Confluence Data Center, the shortcoming has now come under active exploitation in the wild.The bug in question is CVE-2022-26138, which concerns the use of a hard-coded password in the app that could be exploited by a remote, unauthenticated attacker to gain unrestricted access to all pages in Confluence.
