Adobe Flash Player Arbitrary Code Execution
CVE-2015-7645 is a high-severity vulnerability in Flash Player from Adobe, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. Affected Flash Player versions: 18.0.0.160 through 18.0.0.252; 19.0.0.185; 19.0.0.207, and others listed below. The record does not name a fixed version, so check the vendor advisory. CISA added it to the Known Exploited Vulnerabilities catalogue on March 3, 2022, which means attacks have been observed in the wild, including in ransomware campaigns.
Attackers are already exploiting this vulnerability, according to CISA.
What to do
- Check which version of Flash Player you run against the affected versions below, and install the vendor's latest release.
- CISA's required action: The impacted product is end-of-life and should be disconnected if still in use.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.
