Adobe Flash Player Remote Code Execution

CVE-2015-0311 is a critical-severity vulnerability in Flash Player from Adobe, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 16.0.0.287 as the first without the flaw, so updating Flash Player to that release or later removes the exposure. CISA added it to the Known Exploited Vulnerabilities catalogue on April 13, 2022, which means attacks have been observed in the wild.

Patch now

Attackers are already exploiting this vulnerability, according to CISA.

What to do

  1. Update Flash Player to 16.0.0.287 or a later version.
  2. CISA's required action: The impacted product is end-of-life and should be disconnected if still in use.
  3. Read the advisory on helpx.adobe.com for workarounds and exact fixed builds.
  4. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
