Apache Sling POST Servlets Denial of Service Vulnerability

Moderate severity GitHub Reviewed Published May 17, 2022 to the GitHub Advisory Database • Updated Aug 29, 2023

Package

maven org.apache.sling:org.apache.sling.servlets.post (Maven)

Affected versions

< 2.1.2

Patched versions

2.1.2

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.
