CVE-2021-35217

Insecure Deseralization of untrusted data remote code execution vulnerability was discovered in Patch Manager Orion Platform Integration module and reported to us by ZDI. An Authenticated Attacker could exploit it by executing WSAsyncExecuteTasks deserialization of untrusted data.

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.
