IBM Maximo Asset Management 7.6.0 and 7.6.1 could allow a remote authenticated attacker to execute arbitrary code on the system, caused by an unsafe deserialization in Java. By sending specially-crafted request, an attacker could exploit this vulnerability to execute arbitrary code on the system. IBM X-Force ID: 182396.

Weakness

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

Affected Software

Name Vendor Start Version End Version
Maximo_asset_management Ibm 7.6.0 (including) 7.6.0.10 (excluding)
Maximo_asset_management Ibm 7.6.1 (including) 7.6.1.2 (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.
