CWEhttps://cwe.mitre.org/data/definitions/502.html

A potential Remote Arbitrary Code Execution vulnerability has been identified in Micro Focus Real User Monitoring software, versions 9.26IP, 9.30, 9.40 and 9.50. The vulnerability could be exploited to execute arbitrary code.

Weakness

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

Affected Software

Name Vendor Start Version End Version
Real_user_monitoring Microfocus 9.26ip (including) 9.26ip (including)
Real_user_monitoring Microfocus 9.30 (including) 9.30 (including)
Real_user_monitoring Microfocus 9.40 (including) 9.40 (including)
Real_user_monitoring Microfocus 9.50 (including) 9.50 (including)

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.
