Denial of Service Vulnerability in Apache Sling POST Servlet

CVE-2012-2138 · MEDIUM Severity

AV:N/AC:L/AU:N/C:N/I:N/A:P

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.
