Noroxi assessment

Priority: Now (action score 95/100)

  • CISA has confirmed exploitation in the wild (Mar 3, 2022). Remediation deadline for US federal agencies: Mar 24, 2022.
  • A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 99.4% (FIRST EPSS); higher than 99.9% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: flash-plugin (Red Hat:rhel_extras:5::client) 0:10.2.159.1-1.el5; flash-plugin (Red Hat:rhel_extras:6) 0:10.2.159.1-1.el6.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Patch today or shut off access. Upgrade to flash-plugin (Red Hat:rhel_extras:5::client) 0:10.2.159.1-1.el5; flash-plugin (Red Hat:rhel_extras:6) 0:10.2.159.1-1.el6 or later.

Primary sources: NVD · CVE.org · CISA KEV · FIRST EPSS

Adobe Flash Player before 10.2.154.27 on Windows, Mac OS X, Linux, and Solaris and 10.2.156.12 and earlier on Android; Adobe AIR before 2.6.19140; and Authplay.dll (aka AuthPlayLib.bundle) in Adobe Reader 9.x before 9.4.4 and 10.x through 10.0.1 on Windows, Adobe Reader 9.x before 9.4.4 and 10.x before 10.0.3 on Mac OS X, and Adobe Acrobat 9.x before 9.4.4 and 10.x before 10.0.3 on Windows and Mac OS X allow remote attackers to execute arbitrary code or cause a denial of service (application crash) via crafted Flash content; as demonstrated by a Microsoft Office document with an embedded .swf file that has a size inconsistency in a "group of included constants," object type confusion, ActionScript that adds custom functions to prototypes, and Date objects; and as exploited in the wild in April 2011.

Vulnrichment: CISA's decision-tree inputs.

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on Mar 3, 2022. That signals real attacks, not theory.

Remediation deadline for US federal agencies: Mar 24, 2022.
