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

IBM Data Server Driver for JDBC and SQLJ (IBM DB2 for Linux, UNIX and Windows 9.7, 10.1, 10.5, and 11.1) deserializes the contents of /tmp/connlicj.bin which leads to object injection and potentially arbitrary code execution depending on the classpath. IBM X-Force ID: 133999.

Weakness

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

Affected Software

Name Vendor Start Version End Version
Db2 Ibm 9.7 (including) 9.7 (including)
Db2 Ibm 10.1 (including) 10.1 (including)
Db2 Ibm 10.5 (including) 10.5 (including)
Db2 Ibm 11.1 (including) 11.1 (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.
