Who should care

Security teams, endpoint and server owners, vulnerability management teams, and asset owners responsible for any systems that may still have Adobe Flash Player installed or enabled.

Technical summary

The official records identify CVE-2015-7645 as an Adobe Flash Player arbitrary code execution vulnerability. CISA has added it to the Known Exploited Vulnerabilities catalog, indicating active exploitation risk, and notes that the impacted product is end-of-life. The supplied KEV metadata also states that the product should be disconnected if still in use and records known ransomware campaign use as "Known."

Defensive priority

High. The vulnerability is known to be exploited, the affected product is end-of-life, and CISA provides explicit disconnect guidance rather than a normal patch path. The KEV record supplied with this data uses a due date of 2022-03-24.

Recommended defensive actions

  • Inventory systems for any remaining Adobe Flash Player installations or dependencies.
  • Remove Flash Player wherever possible; if removal is not immediately feasible, disconnect affected systems from networks as CISA advises.
  • Prioritize isolation of any internet-facing or business-critical hosts that still rely on Flash Player.
  • Validate that compensating controls and application dependencies do not silently reintroduce Flash content or Flash-enabled workflows.
  • Track remediation against the KEV due date and confirm the affected product is no longer in service.
