CVE-2022-1984

This issue affects: HYPR Windows WFA versions prior to 7.2; Unsafe Deserialization vulnerability in HYPR Workforce Access (WFA) before version 7.2 may allow local authenticated attackers to elevate privileges via a malicious serialized payload.

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.
