What is CVE-2012-2138?

The @CopyFrom operation in the POST servlet of Apache Sling versions prior to 2.1.2 is susceptible to a denial of service vulnerability. This issue arises when the system fails to prevent unauthorized attempts to copy an ancestor node to a descendant node. By sending a specifically crafted HTTP request, an attacker can exploit this vulnerability, triggering an infinite loop within the system that leads to service interruption. It's crucial for users to be aware of this risk and to update to the latest version to mitigate potential attacks.
