CVE-2024-32007 is a high-severity vulnerability found in the Apache CXF framework, specifically in the JOSE code. This vulnerability allows an attacker to perform a denial of service attack by improperly validating the p2c parameter. By specifying a large value for this parameter in a token, attackers can potentially exhaust system resources, leading to service disruptions.
The vulnerability has a CVSS score of 7.5, indicating a high severity level. Its impact is primarily on availability, as it can lead to denial of service, affecting the overall functionality of applications utilizing Apache CXF. With the increasing reliance on web services and APIs, the exploitation of this vulnerability poses a significant risk to organizations.
Currently, there are no known exploits or public proof of concept available, but the potential for exploitation exists. Organizations using affected versions of Apache CXF should prioritize remediation efforts to avoid potential disruptions.
Organizations should prioritize patching immediately. The affected versions include those prior to 4.0.5, 3.6.4, and 3.5.9. Timely updates to the latest versions are crucial in maintaining security.
Vulnerability Details
An improper input validation of the p2c parameter in the Apache CXF JOSE code before 4.0.5, 3.6.4, and 3.5.9 allows an attacker to perform a denial of service attack by specifying a large value for this parameter in a token.
The vulnerability has been classified with a CVSS score of 7.5, indicating high severity. The affected products include Apache CXF versions prior to 4.0.5, 3.6.4, and 3.5.9, with a CWE classification of CWE-20 (Improper Input Validation) and CWE-400 (Uncontrolled Resource Consumption).
Technical Analysis
The root cause of CVE-2024-32007 lies in the improper validation of input parameters, particularly for the p2c parameter. This vulnerability is exploitable via network access, allowing attackers to send crafted requests that could result in resource exhaustion.
The attack complexity is considered low, as no special privileges or user interaction is required to exploit this vulnerability. The attack vector is network-based, making it accessible to external threats. As a result, the availability impact is rated high, indicating that successful exploitation can lead to significant service interruptions.
Risk & Impact Analysis
Risk to organizations includes potential service outages and disruptions caused by denial of service attacks. The blast radius is significant, as many systems relying on Apache CXF could be affected if this vulnerability is exploited. Organizations should address in priority patch cycle to mitigate risks associated with this vulnerability.
Exploitation Status
