The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday announced the inclusion of 11 security holes in its Known Exploited Vulnerabilities Catalog.
CISA created the list – which now contains roughly 500 flaws – to help federal agencies prioritize patching within their environments. CISA told SecurityWeek it has evidence of in-the-wild exploitation for all of the security issues on the list.
The most recent of the newly added bugs are two zero-day vulnerabilities in Firefox, for which Mozilla issued an emergency update over the weekend.
Tracked as CVE-2022-26485 and CVE-2022-26486 and rated “critical severity,” the security holes are described as use-after-free issues. This type of flaw usually leads to arbitrary code execution.
Firefox 97.0.2, Firefox ESR 91.6.1, Firefox for Android 97.3.0, and Focus 97.3.0 address the bugs and federal agencies have until March 21 to update to a patched version. By default, Firefox is configured to automatically install updates and manual patching is required only if this default setting is disabled.
On Monday, CISA also added to its ‘Must-Patch’ list a vulnerability in VMware vCenter Server and Cloud Foundation Server. Tracked as CVE-2021-21973 (CVSS score of 5.3), the issue was addressed in February 2021.
The security error is described as “an SSRF (Server Side Request Forgery) vulnerability due to improper validation of URLs in a vCenter Server plugin.” To exploit the issue, an attacker with access to port 443 can send a POST request to the vCenter Server plugin.
While patches for this bug should be installed by March 21, federal agencies have until September 7 to resolve the remaining 8 flaws that were added to the Known Exploited Vulnerabilities Catalog this week.
These vulnerabilities are even older and they affect Pulse Connect Secure, Atlassian Jira, NETGEAR routers, Adobe ColdFusion, and Adobe BlazeDS.
While CISA’s Must-Patch catalog and the accompanying Binding Operational Directive (BOD) 22-01 are aimed at federal agencies, organizations of all types are advised to review the list and address the issues on it as soon as possible.
