In BIG-IP Versions 16.1.x before 16.1.3, 15.1.x before 15.1.6.1, 14.1.x before 14.1.5, and all versions of 13.1.x, a vulnerability exists in undisclosed pages of the BIG-IP DNS Traffic Management User Interface (TMUI) that allows an authenticated attacker with at least operator role privileges to cause the Tomcat process to restart and perform unauthorized DNS requests and operations through undisclosed requests. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

Weakness

The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

Affected Software

Name Vendor Start Version End Version
Big-ip_domain_name_system F5 13.1.0 (including) 13.1.5 (including)
Big-ip_domain_name_system F5 14.1.0 (including) 14.1.5 (excluding)
Big-ip_domain_name_system F5 15.1.0 (including) 15.1.6.1 (excluding)
Big-ip_domain_name_system F5 16.1.0 (including) 16.1.3 (excluding)

Potential Mitigations

  • Make fields transient to protect them from deserialization.
  • An attempt to serialize and then deserialize a class containing transient fields will result in NULLs where the transient data should be. This is an excellent way to prevent time, environment-based, or sensitive variables from being carried over and used improperly.
