An issue found in MIM software Inc MIM License Server and MIMpacs services v.6.9 thru v.7.0 fixed in v.7.0.10 allows a remote unauthenticated attacker to execute arbitrary code via the RMI Registry service.

Weakness

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

Affected Software

Name Vendor Start Version End Version
Mim_concurrent_license_server Mimsoftware 6.5.0 (including) 7.0.9 (including)
Mim_local_concurrent_license_server Mimsoftware 6.5.0 (including) 7.0.9 (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.
