CVE-2022-34169: Apache Xalan Java XSLT library is vulnerable to an integer truncation issue when processing malicious XSLT stylesheets

Noroxi assessment

Priority: Plan (action score 55/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 81.7% (FIRST EPSS); higher than 99.6% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: java-1.8.0-openjdk (AlmaLinux:8) 1:1.8.0.342.b07-2.el8_6; java-1.8.0-openjdk-accessibility (AlmaLinux:8) 1:1.8.0.342.b07-2.el8_6; java-1.8.0-openjdk-accessibility-fastdebug (AlmaLinux:8) 1:1.8.0.342.b07-2.el8_6.
  • Mentioned 2 times in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Add it to your regular patch cycle. Upgrade to java-1.8.0-openjdk (AlmaLinux:8) 1:1.8.0.342.b07-2.el8_6; java-1.8.0-openjdk-accessibility (AlmaLinux:8) 1:1.8.0.342.b07-2.el8_6; java-1.8.0-openjdk-accessibility-fastdebug (AlmaLinux:8) 1:1.8.0.342.b07-2.el8_6 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The Apache Xalan Java XSLT library is vulnerable to an integer truncation issue when processing malicious XSLT stylesheets. This can be used to corrupt Java class files generated by the internal XSLTC compiler and execute arbitrary Java bytecode. Users are recommended to update to version 2.7.3 or later. Note: Java runtimes (such as OpenJDK) include repackaged copies of Xalan.
