CVE-2024-9953

A potential denial-of-service (DoS) vulnerability exists in CERT VINCE software versions prior to 3.0.8. An authenticated administrative user can inject an arbitrary pickle object into a user’s profile, which may lead to a DoS condition when the profile is accessed. While the Django server restricts unpickling to prevent server crashes, this vulnerability could still disrupt operations.

Weakness

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

Affected Software

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.
