CISA KEV Advisory
Adobe Flash Player Heap-Based Buffer Overflow Vulnerability
Heap-based buffer overflow vulnerability in Adobe Flash Player allows remote attackers to execute code.
The impacted product is end-of-life and should be disconnected if still in use.
Risk Analysis
A heap-based buffer overflow in Adobe Flash Player allows remote attackers to execute arbitrary code on affected systems. The extremely high EPSS score of 0.92420 indicates a very high likelihood of exploitation. This vulnerability is confirmed to be actively exploited, making it a critical threat.
This vulnerability is actively exploited in the wild and is listed in CISA's Known Exploited Vulnerabilities catalog. Attackers are leveraging this flaw for remote code execution.
Users should uninstall Adobe Flash Player as it is end-of-life and no longer supported. If uninstallation is not immediately possible, ensure all available security updates are applied, though complete removal is the recommended long-term solution.
Technical Analysis
CVE-2015-3113 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2015-3113 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
