CVE-2012-2138 – Apache Sling - Denial of Service

https://notcve.org/view.php?id=CVE-2012-2138

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. La operación @CopyFrom en el servlet POST en el conjunto org.apache.sling.servlets.post anteriores a v2.1.2 en Apache Sling no previene intentos de copia sobre un nodo de nivel superior sobre uno de nivel inferior, lo que permite a atacantes remotos provocar una denegación de servicio (bucle infinito) a través de una petición HTTP. The CopyFrom operation of the Sling POST servlet allows for copying a parent node to one of its descendant nodes, creating an infinite loop that ultimately results in denial of service, once memory and/or storage resources are exhausted. • https://www.exploit-db.com/exploits/37487 http://mail-archives.apache.org/mod_mbox/www-announce/201207.mbox/%3CCAEWfVJ=PwoQmwJg0KmbrC17Gw51kgfKRsqgy=4RpMQsdGh0bVg%40mail.gmail.com%3E http://svn.apache.org/viewvc?view=revision&revision=1352865 https://issues.apache.org/jira/browse/SLING-2517 • CWE-264: Permissions, Privileges, and Access Controls •
