Technical summary

The supplied source corpus identifies CVE-2015-3043 as an Adobe Flash Player memory corruption vulnerability. CISA added it to the KEV catalog on 2022-03-03 and set a due date of 2022-03-24. The KEV record states that the impacted product is end-of-life and should be disconnected if still in use.

Defensive priority

Urgent. CISA lists this as a known exploited vulnerability, and the product is end-of-life, so remediation should focus on removal and disconnection rather than patching.

Recommended defensive actions

  • Inventory all hosts, browsers, plugins, and embedded environments for any remaining Adobe Flash Player presence.
  • Remove or disable Adobe Flash Player wherever it is found; do not keep it enabled for general use.
  • If immediate removal is not possible, disconnect affected systems from networks until Flash is eliminated.
  • Review dependent applications and replace any workflows that still require Flash with supported alternatives.
  • Verify that browser settings, plugins, and endpoint management policies prevent reintroduction of Flash components.
