A vulnerability, which was classified as critical, has been found in cym1102 nginxWebUI up to 3.9.9. This issue affects the function exec of the file /adminPage/conf/reload. The manipulation of the argument nginxExe leads to deserialization. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The associated identifier of this vulnerability is VDB-260579.

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.
