CVE-2024-32007
Description
An improper input validation vulnerability was found in the p2c parameter in the Apache CXF JOSE. This flaw allows an attacker to perform a denial of service attack by specifying a large value for this parameter in a token.
Statement
The improper input validation vulnerability in the p2c parameter of Apache CXF JOSE is considered a moderate severity issue rather than a important one due to its limited scope and impact. While the flaw allows an attacker to specify a large value for the p2c parameter, leading to potential denial of service (DoS) attacks by causing excessive computational overhead, it does not compromise data integrity, confidentiality, or authentication mechanisms directly. The attack vector primarily affects system availability and exploiting this vulnerability requires the ability to send crafted tokens.
Base EAP (7.4 and 8) and EAP XP (4 and 5) do not ship this affected CXF jaxrs artifact. cxf-rt-rs-security-jose is part of CXF's JAX-RS, and EAP uses RESTEasy, hence it's not-affected.
Mitigation
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Resource Consumption (Other)
When allocating resources without limits, an attacker could prevent other systems, applications, or processes from accessing the same type of resource. It can be easy for an attacker to consume many resources by rapidly making many requests or causing larger resources to be used than is needed.
