Published Sep 30, 2024CWE-502EPSS 0.58%

Overview

CVE-2024-45772 is a medium-severity vulnerability. It was published on September 30, 2024 and has a CVSS 3.1 base score of 5.1 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.1, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
