Oracle Java SE Unspecified

Published Updated By the CyberSecBulletin desk

CVE-2013-2465 is a high-severity protection mechanism failure vulnerability in JRE from Oracle, 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. Affected JRE versions: 1.7.0; 1.6.0; 1.5.0. The record does not name a fixed version, so check the vendor advisory. CISA added it to the Known Exploited Vulnerabilities catalogue on March 28, 2022, which means attacks have been observed in the wild, including in ransomware campaigns.

Patch now

Attackers are already exploiting this vulnerability, according to CISA.

What to do

  1. Check which version of JRE you run against the affected versions below, and install the vendor's latest release.
  2. CISA's required action: Apply updates per vendor instructions.
  3. Read the advisory on oracle.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

Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 21 and earlier, 6 Update 45 and earlier, and 5.0 Update 45 and earlier, and OpenJDK 7, allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to 2D. NOTE: the previous information is from the June 2013 CPU. Oracle has not commented on claims from another vendor that this issue allows remote attackers to bypass the Java sandbox via vectors related to "Incorrect image channel verification" in 2D.
