Who should care

Organizations that still have Adobe Flash Player installed or embedded in legacy workflows, especially endpoint, desktop, application support, and vulnerability management teams. Asset owners should care most if any systems are still allowed to load Flash content or retain Flash Player components.

Technical summary

The vulnerability is described as an Adobe Flash Player incorrect default permissions issue. The supplied sources do not provide exploit mechanics or impact details beyond the title and the fact that it is listed in CISA KEV. The key operational point is that Flash Player is end-of-life, so remediation is not patching in place but eliminating the product from the environment.

Defensive priority

High. CISA has identified this CVE in its Known Exploited Vulnerabilities catalog, which indicates known real-world exploitation and a required remediation deadline in the KEV program. For an end-of-life product, remediation should be treated as urgent removal/containment rather than routine patching.

Recommended defensive actions

  • Inventory endpoints, virtual machines, and legacy applications for any remaining Adobe Flash Player presence.
  • Remove or disable Adobe Flash Player wherever it is still installed or enabled.
  • Replace any workflow that still depends on Flash content with a supported alternative.
  • Block or restrict access to legacy Flash content paths until retirement is complete.
  • Verify that security tools, software distribution, and application allowlists no longer permit Flash Player components.
  • Track remediation against the KEV due date of 2024-10-08 and confirm no residual dependencies remain.

Evidence notes

This debrief is limited to the supplied CISA KEV metadata and official CVE/NVD/CISA links. The source record identifies the issue as 'Adobe Flash Player Incorrect Default Permissions Vulnerability,' marks it as KEV-listed, and states the product is end-of-life/end-of-service with the required action to discontinue use. No CVSS score was provided in the supplied corpus.
