Improper Restriction of Operations within the Bounds of a Memory Buffer

CVE-2013-2254

Medium
5/10

Summary

The deepGetOrCreateNode function in impl/operations/AbstractCreateOperation.java in org.apache.sling.servlets.post in Apache Sling up to 2.3.0 does not properly handle a NULL value that returned when the session does not have permissions to the root node, which allows remote attackers to cause a denial of service (infinite loop) via unspecified vectors.

CWE-119 - Buffer Overflow

Buffer overflow attacks involve data transit and operations exceeding the restricted memory buffer, thereby corrupting or overwriting data in adjacent memory locations. Such overflow allows the attacker to run arbitrary code or manipulate the existing code to cause privilege escalation, data breach, denial of service, system crash and even complete system compromise. Given that languages such as C and C++ lack default safeguards against overwriting or accessing data in their memory, applications utilizing these languages are most susceptible to buffer overflows attacks.
