CVE-2023-48952

An issue in the box_deserialize_reusing function in openlink virtuoso-opensource v7.2.11 allows attackers to cause a Denial of Service (DoS) after running a SELECT statement.

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.
