CVE-2024-4019

A vulnerability classified as critical has been found in Byzoro Smart S80 Management Platform up to 20240411. Affected is an unknown function of the file /importhtml.php. The manipulation of the argument sql leads to deserialization. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. VDB-261666 is the identifier assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.

Weakness

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

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.
