Automated analysis

Generated by VULONE's analysis model from the NVD record, CISA KEV and EPSS data on 18 September 2026. Confidence: high.

high priorityRemote code execution with complete impact and confirmed in-the-wild exploitation, though the product is legacy and the record lacks modern KEV listing.

What it is

Adobe Flash Player contains an object confusion vulnerability that lets a crafted file corrupt memory and execute arbitrary code. It affects Flash Player before 10.3.183.19 and 11.x before 11.2.202.235 on Windows, Mac OS X and Linux, plus specific Android builds. The flaw was exploited in the wild in May 2012, making it a serious client-side risk.

Impact

An attacker can execute arbitrary code in the context of the user running Flash Player, giving full control of the affected system. The CVSS 2.0 vector shows complete confidentiality, integrity and availability impact.

Attack surface

Reached remotely by delivering a crafted file that Flash Player processes, typically through a web page or embedded content. No authentication is required, but the CVSS vector indicates medium access complexity and some user interaction is needed to load the malicious content.

Exploitation

The description states the vulnerability was exploited in the wild in May 2012. It is not listed in CISA KEV, but EPSS is very high at 0.85537 (99.71st percentile), indicating strong likelihood of exploitation activity.

What to do

  • Update Flash Player to 10.3.183.19 or later, or 11.2.202.235 or later on Windows, Mac OS X and Linux, and to the fixed Android versions (11.1.111.9 for Android 2.x/3.x, 11.1.115.8 for Android 4.x).
  • Apply vendor and distribution patches referenced in Adobe APSB12-09, Red Hat RHSA-2012-0688 and openSUSE advisories.
  • Disable or remove Flash Player where it is not required, and restrict browser plug-in execution.
  • Block or control untrusted Flash content at the network and email gateway.
  • Monitor for and remove legacy Flash installations that cannot be patched.

Detection

  • Hunt for Flash Player versions below the fixed builds on endpoints and report them.
  • Monitor process creation and memory behavior of Flash Player for signs of exploitation.
  • Review proxy and IDS logs for delivery of crafted SWF or Flash-embedded files.
  • Check for unexpected child processes spawned by browser or Flash Player processes.

This assessment is produced automatically and is not human-reviewed. Verify against the vendor advisory before acting on it.
