CVE-2012-2138

Name of the Vulnerable Software and Affected Versions Apache Sling versions prior to 2.1.2

Description The issue allows remote attackers to cause a denial of service (infinite loop) via a crafted HTTP request. This is due to the @CopyFrom operation in the POST servlet not preventing attempts to copy an ancestor node to a descendant node.

Recommendations For versions prior to 2.1.2, update to version 2.1.2 or later to resolve the issue. As a temporary workaround, consider restricting access to the POST servlet to minimize the risk of exploitation.
