Technical details
Apache Neethi is vulnerable to uncontrolled resource consumption (CWE-400). The vulnerability exists because certain crafted policies can bypass the maximum number of normalized policy alternatives limit introduced in version 3.2.2. An attacker can exploit this by submitting a malicious policy for processing, leading to excessive CPU or memory consumption and a denial-of-service (DoS) condition. The issue is resolved in Apache Neethi version 3.2.3.
Affected products
