CVE-2024-43383

Deserialization of Untrusted Data vulnerability in Apache Lucene.Net.Replicator.

This issue affects Apache Lucene.NETs Replicator library: from 4.8.0-beta00005 through 4.8.0-beta00016.

An attacker that can intercept traffic between a replication client and server, or control the target replication node URL, can provide a specially-crafted JSON response that is deserialized as an attacker-provided exception type. This can result in remote code execution or other potential unauthorized access.

Users are recommended to upgrade to version 4.8.0-beta00017, which fixes the issue.

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.
