CVE-2015-0310Exploited in the wildNVD status: Analyzed

Adobe Flash Player ASLR Bypass

Published Updated By the CyberSecBulletin desk

CVE-2015-0310 is a high-severity exposure of sensitive information to an unauthorized actor vulnerability in Flash Player from Adobe, with a CVSS 2.0 base score of 10.0 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists versions 11.2.202.438, 13.0.0.262, 16.0.0.287 as the first without the flaw, so updating Flash Player to one of those releases or later removes the exposure. CISA added it to the Known Exploited Vulnerabilities catalogue on May 25, 2022, which means attacks have been observed in the wild.

Patch now

Attackers are already exploiting this vulnerability, according to CISA.

What to do

  1. Update Flash Player to 11.2.202.438 or 13.0.0.262 or 16.0.0.287, whichever matches your release line, or a later version.
  2. CISA's required action: The impacted product is end-of-life and should be disconnected if still in use.
  3. Read the advisory on helpx.adobe.com for workarounds and exact fixed builds.
  4. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

Adobe Flash Player before 13.0.0.262 and 14.x through 16.x before 16.0.0.287 on Windows and OS X and before 11.2.202.438 on Linux does not properly restrict discovery of memory addresses, which allows attackers to bypass the ASLR protection mechanism on Windows, and have an unspecified impact on other platforms, via unknown vectors, as exploited in the wild in January 2015.

The underlying weakness: Exposure of Sensitive Information to an Unauthorized Actor

The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.

How developers prevent this class of flaw

  • Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
