A bypass vulnerability in Apache Neethi permits attackers to circumvent policy normalization limits, creating a high risk of denial of service.

This vulnerability involves the bypass of security limits regarding the maximum number of normalized policy alternatives (CWE-400). It allows an unauthenticated remote attacker to trigger excessive resource consumption.

By bypassing normalization limits, an attacker can force the application to consume excessive resources, leading to potential system instability or a complete denial of service. With a CVSS score of 7.5, this vulnerability represents a significant risk to the availability of services dependent on this library.

Immediate Action: Update Apache Neethi to version 3.2.3 or later to ensure that policy normalization limits are properly enforced.

Proactive Monitoring: Review application logs for patterns indicating unauthorized or excessive policy processing requests.

Compensating Controls: Utilize rate limiting or traffic shaping at the network perimeter to mitigate potential high-volume resource consumption attacks.

Public Exploit Available: No (exploit_available: unknown)

The inability to properly enforce policy normalization limits poses a direct threat to system availability. Organizations should move quickly to update the affected Apache Neethi component to version 3.2.3 to ensure these protections are active and effective.
