IBM Sterling B2B Integrator Standard Edition 5.2.0.0 through 5.2.6.5_2, 6.0.0.0 through 6.0.3.2, and 6.1.0.0 could allow a remote attacker to execute arbitrary code on the system, caused by the deserialization of untrusted data. By sending specially crafted request, an attacker could exploit this vulnerability to execute arbitrary code with SYSTEM privileges. IBM X-Force ID: 172452.

Weakness

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

Affected Software

Name Vendor Start Version End Version
Sterling_b2b_integrator Ibm 5.2.0.0 (including) 5.2.6.5_2 (including)
Sterling_b2b_integrator Ibm 6.0.0.0 (including) 6.0.3.2 (including)
Sterling_b2b_integrator Ibm 6.1.0.0 (including) 6.1.0.0 (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.
