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.
Affected configurations
| CPE | Name | Operator | Version |
|---|---|---|---|
| org.apache.sling:org.apache.sling.servlets.post | lt | 2.1.2 |
