Apache Sling POST Servlets Denial of Service Vulnerability

MEDIUM 5.0CVE-2012-2138 · GHSA-342c-f869-5m44 · Published 09/07/2012 · updated 16/06/2026

Package	Affected versions	Patched versions
org.apache.sling:org.apache.sling.servlets.post Maven	`< 2.1.2`	`2.1.2`
org.apache.sling.servlets.post apache	`≤ 2.1.0`	No fix yet

Description

The @CopyFrom operation in the POST servlet in the org.apache.sling.servlets.post bundle before 2.1.2 in Apache Sling does not prevent attempts to copy an ancestor node to a descendant node, which allows remote attackers to cause a denial of service (infinite loop) via a crafted HTTP request.
