CVE-2024-45772 Apache Lucene Replicator: Security Vulnerability in Lucene Replicator - Deserialization Issue

What is CVE-2024-45772?

CVE-2024-45772 is a medium-severity unsafe deserialization vulnerability in Apache Lucene Replicator, published on 30 Sep 2024. It can only be exploited from the same machine or local network, with no action from the victim.

Official description

Deserialization of Untrusted Data vulnerability in Apache Lucene Replicator.

This issue affects Apache Lucene's replicator module: from 4.4.0 before 9.12.0. The deprecated org.apache.lucene.replicator.http package is affected. The org.apache.lucene.replicator.nrt package is not affected.

Users are recommended to upgrade to version 9.12.0, which fixes the issue.

The deserialization can only be triggered if users actively deploy an network-accessible implementation and a corresponding client using a HTTP library that uses the API (e.g., a custom servlet and HTTPClient). Java serialization filters (such as -Djdk.serialFilter='!*' on the commandline) can mitigate the issue on vulnerable versions without impacting functionality.

Weakness: CWE-502
