CVE-2024-55637 is a critical vulnerability affecting Drupal Core, classified under CVSS with a score of 9.8. This vulnerability allows deserialization of untrusted data, which could lead to object injection. Specifically, it impacts all versions of Drupal Core from 8.0.0 before 10.2.11, from 10.3.0 before 10.3.9, and from 11.0.0 before 11.0.8. The severity of this issue is underscored by its potential to facilitate remote code execution if exploited alongside another vulnerability.
The exploitation of this vulnerability hinges on a chain of methods within Drupal Core that becomes dangerous when an insecure deserialization vulnerability exists. While the gadget chain itself does not present a direct threat, it serves as a vector for exploitation if untrusted data is deserialized due to other vulnerabilities. As such, the risk to organizations includes unauthorized access and manipulation of sensitive data.
Given the critical nature of this vulnerability, organizations using affected versions of Drupal Core should prioritize patching immediately. The urgency is heightened by the high CVSS score, highlighting the need for swift remediation efforts to protect against potential exploitation.
In terms of exploitation status, there are currently no known public exploits or proofs of concept available. However, the nature of the vulnerability warrants close attention, as attackers may leverage it if combined with other weaknesses in the system.
For organizations running affected versions, the time to act is now. A proactive approach to patching this vulnerability will significantly mitigate risks associated with potential attacks.
Vulnerability Details
The official description of CVE-2024-55637 indicates that it is a deserialization of untrusted data vulnerability within Drupal Core, allowing for object injection. The issue affects multiple versions, including all versions from 8.0.0 before 10.2.11, from 10.3.0 before 10.3.9, and from 11.0.0 before 11.0.8. The vulnerability is classified as CWE-502 (Deserialization of Untrusted Data) and CWE-915 (Improperly Controlled Modification of Object Prototype Attributes).
This vulnerability carries a CVSS score of 9.8, categorized as critical. The attack vector is network-based, with low complexity and no privileges required for exploitation. User interaction is not necessary, and the impacts on confidentiality, integrity, and availability are all rated as high.
Technical Analysis
The root cause of this vulnerability lies in the insecure handling of deserialization processes within Drupal Core. The attack vector is primarily network-based, allowing attackers to exploit this vulnerability remotely. The attack complexity is rated as low, indicating that potential attackers do not require advanced skills to exploit the vulnerability.
Exploitation does not require any privileges, and user interaction is also not necessary, which enhances the potential for exploitation. The impacts of this vulnerability are severe, affecting confidentiality, integrity, and availability, all rated as high. Such characteristics make this vulnerability particularly dangerous to organizations relying on Drupal.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2024-55637 is significant. Organizations that fail to mitigate this vulnerability may face unauthorized access and potential data breaches. The blast radius could be extensive, impacting various components of affected systems and potentially leading to a compromise of sensitive information.
Given the CVSS score of 9.8 and the KEV status indicating it is not currently in the KEV catalog, the urgency for organizations to address this vulnerability is critical. Organizations should prioritize patching to prevent exploitation, as the vulnerability could be leveraged in conjunction with other weaknesses within their systems.
