Description

Deserialization of Untrusted Data vulnerability in Apache Lucene.Net.Replicator. This issue affects Apache Lucene.NET's 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.

Affected products

Apache Software Foundation Apache Lucene.Net: 4.8.0-beta00005, 4.8.0-beta00006, 4.8.0-beta00007, 4.8.0-beta00008, 4.8.0-beta00009, 4.8.0-beta00010 (+6)
