Noroxi assessment

Priority: This week (action score 68/100)

CISA has confirmed exploitation in the wild (Sep 17, 2024). Remediation deadline for US federal agencies: Oct 8, 2024.
Probability of exploitation in the next 30 days: 10.5% (FIRST EPSS); higher than 95.8% 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::server) 0:11.2.202.273-1.el5; flash-plugin (Red Hat:rhel_extras:6) 0:11.2.202.273-1.el6.

Don’t wait for the next maintenance window. Upgrade to flash-plugin (Red Hat:rhel_extras:5::server) 0:11.2.202.273-1.el5; flash-plugin (Red Hat:rhel_extras:6) 0:11.2.202.273-1.el6 or later.

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

The Firefox sandbox in Adobe Flash Player before 10.3.183.67 and 11.x before 11.6.602.171 on Windows and Mac OS X, and before 10.3.183.67 and 11.x before 11.2.202.273 on Linux, does not properly restrict privileges, which makes it easier for remote attackers to execute arbitrary code via crafted SWF content, as exploited in the wild in February 2013.
