CISA urges to fix actively exploited Firefox zero-days by March 21

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added recently disclosed Firefox zero-days to its Known Exploited Vulnerabilities Catalog.

The Cybersecurity and Infrastructure Security Agency (CISA) added two critical security vulnerabilities in Mozilla firefox, tracked as CVE-2022-26485 and CVE-2022-26486, to its Known Exploited Vulnerabilities Catalog. The US agency has ordered federal civilian agencies to address both issues by March 21, 2022.

Yesterday Mozilla has released Firefox 97.0.2, Firefox ESR 91.6.1, Firefox for Android 97.3.0, and Focus 97.3.0 to address the two zero-day vulnerabilities that are actively exploited in attacks.

The two vulnerabilities are “Use-after-free” issues in XSLT parameter processing and in the WebGPU IPC Framework respectively.

Successful exploitation of the flaws can cause a program crash or execute arbitrary commands on the machine.

Below is the description of both flaws included in the advisory published by Mozilla:

CVE-2022-26485: Removing an XSLT parameter during processing could have lead to an exploitable use-after-free. We have had reports of attacks in the wild abusing this flaw.CVE-2022-26486: An unexpected message in the WebGPU IPC framework could lead to a use-after-free and exploitable sandbox escape. 

According to Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities, FCEB agencies have to address the identified vulnerabilities by the due date to protect their networks against attacks exploiting the flaws in the catalog.

Experts recommend also private organizations review the Known Exploited Vulnerabilities Catalog and address the vulnerabilities in their infrastructure.

CISA added nine other vulnerabilities to its Known Exploited Vulnerabilities Catalog that are reported in the following table along with the associated due date.
