CVE-2024-36401 is a critical vulnerability affecting GeoServer and GeoTools, with a CVSS score of 9.8. This vulnerability allows unauthenticated users to execute arbitrary code through specially crafted input, exploiting multiple OGC request parameters due to unsafely evaluating property names as XPath expressions. The risk to organizations includes unauthorized access and potential data breaches.
The vulnerability is present in all versions prior to 2.22.6, 2.23.6, 2.24.4, and 2.25.2. It is classified under CWE-94 and CWE-95, indicating improper neutralization of input and code injection, respectively. Organizations using affected versions are at high risk of exploitation, which could lead to severe consequences.
The urgency for defenders is high, as this vulnerability has been confirmed to be exploitable through various requests including WFS GetFeature and WMS GetMap. Organizations should prioritize patching immediately to mitigate this risk.
No public proof of concept (PoC) is available, but the vulnerability has been analyzed and is included in the Known Exploited Vulnerabilities catalog (KEV). This further emphasizes the need for organizations to take immediate action.
Patch versions are available, and a workaround involves removing the `gt-complex-x.y.jar` file from the GeoServer installation. However, this workaround may disrupt some functionalities, indicating the necessity for a proper patch.
Organizations should also consider implementing additional security measures and monitoring to detect any suspicious activity related to this vulnerability.
Vulnerability Details
GeoServer allows users to share and edit geospatial data. The vulnerability arises when the GeoTools library API evaluates property names for feature types, leading to unsafe execution of XPath expressions. This flaw applies to all GeoServer instances, making it a widespread concern.
The vulnerability is present in versions prior to 2.22.6, 2.23.6, 2.24.4, and 2.25.2. Organizations are encouraged to upgrade to these patched versions to secure their systems.
The vulnerability was published on July 1, 2024, and has been marked as critical due to its potential impact on confidentiality, integrity, and availability.
Technical Analysis
The root cause of CVE-2024-36401 is the improper evaluation of property names as XPath expressions within the GeoTools library. This vulnerability exploits the fact that the evaluation mechanism was designed for complex feature types but was improperly applied to simple feature types.
The attack vector is network-based, allowing remote attackers to exploit the vulnerability without the need for authentication. The complexity of the attack is low, requiring no special privileges or user interaction.
The impact on confidentiality, integrity, and availability is high, as attackers may leverage this vulnerability to execute arbitrary code, compromising the entire server.
Risk & Impact Analysis
The risk to organizations includes unauthorized access, data breaches, and potential for further exploitation within internal networks. The blast radius is significant, as all instances of GeoServer are affected, emphasizing the need for prompt action.
Organizations should address this vulnerability in their priority patch cycle, as the potential for exploitation is high. The vulnerability is included in the KEV catalog, which indicates its increased likelihood of being targeted by attackers.

Affected Versions
Affected versions include all GeoServer versions prior to 2.22.6, 2.23.6, 2.24.4, and 2.25.2. Organizations using these versions should upgrade immediately to mitigate the risk.
Mitigation & Remediation
To remediate CVE-2024-36401, organizations should upgrade to GeoServer versions 2.22.6, 2.23.6, 2.24.4, or 2.25.2. If immediate upgrading is not feasible, a temporary workaround is to remove the `gt-complex-x.y.jar` file from the GeoServer installation. However, this workaround may affect some functionalities.
Organizations should also implement security measures such as network controls to restrict access to the GeoServer and monitor for any suspicious activities. Regular security assessments, including penetration testing, can help identify vulnerabilities and improve the overall security posture.
Detection Guidance
To detect potential exploitation of CVE-2024-36401, organizations should monitor logs for unusual access patterns and failed authentication attempts. Behavioral anomalies in application interactions with GeoServer could indicate attempts to exploit the vulnerability.
Network signatures for WFS and WMS requests should be analyzed to identify any suspicious activity. Any unexpected changes in the system, especially in features that utilize XPath expressions, should trigger further investigation.
