A CWE-502: Deserialization of Untrusted Data vulnerability exists which could allow an attacker to execute arbitrary code on the targeted system with SYSTEM privileges when placing a malicious user to be authenticated for this vulnerability to be successfully exploited. Affected Product: Schneider Electric Software Update (SESU) SUT Service component (V2.1.1 to V2.3.0)

Weakness

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

Affected Software

Name Vendor Start Version End Version
Software_update Schneider-electric 2.1.1 (including) 2.3.0 (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.
