Vulnerability Details
The official description for CVE-2024-4956 states that it is a path traversal vulnerability in Sonatype Nexus Repository 3, allowing an unauthenticated attacker to read system files. This vulnerability is classified under CWE-22, which pertains to improper limitation of a pathname to a restricted directory.
The CVSS score for this vulnerability is 7.5, indicating a high severity level. The vulnerability can be exploited over the network with low attack complexity and does not require any privileges or user interaction. The impact is classified as high for confidentiality, while integrity and availability impacts are deemed none.
The vulnerability was published on May 16, 2024, and organizations are encouraged to address it promptly to minimize potential risks.
Technical Analysis
The root cause of CVE-2024-4956 stems from improper input validation in file path handling, allowing attackers to traverse directories and access sensitive files outside of the intended directory. The attack vector is network-based, enabling remote exploitation of the vulnerability.
The attack complexity is low, as it does not require any authentication or specific user privileges, allowing any unauthenticated user to exploit the vulnerability. There is no user interaction required for the exploitation process.
The confidentiality impact is high, as sensitive files may be read by attackers, while the integrity and availability impacts are negligible. Organizations must ensure proper validation and sanitization of user inputs to mitigate such risks effectively.
Risk & Impact Analysis
Real-world deployment risks associated with CVE-2024-4956 are significant, as the ability to read system files can lead to unauthorized access to sensitive information. Attackers can potentially exploit this vulnerability to obtain credentials or other critical data that may allow further attacks within the network.
The blast radius of this vulnerability is extensive, especially for organizations that rely on Sonatype Nexus Repository 3 for software distribution and management. The urgency assessment based on the CVSS score and known exploit availability indicates that organizations should address this vulnerability in their priority patch cycle.
Organizations are advised to engage in proactive security measures, including monitoring for any signs of exploitation attempts and ensuring that appropriate security controls are in place to mitigate the impact of potential breaches.
