Apache Sling POST Servlets Denial of Service Vulnerability

Published: 5/17/2022Modified: 12/6/2024

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.

Affected packages (1)

Maven/org.apache.sling:org.apache.sling.servlets.postfrom 0, < 2.1.2
