A vulnerability, which was classified as critical, has been found in PHPEMS up to 1.0. Affected by this issue is the function index of the file app/weixin/controller/index.api.php. The manipulation of the argument picurl leads to deserialization. The exploit has been disclosed to the public and may be used. VDB-253226 is the identifier assigned to this vulnerability.
Weakness
The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.
Affected Software
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| Phpems | Phpems | * | 1.0 (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.
