A vulnerability classified as medium severity has been identified in Sonatype Nexus Repository. This vulnerability allows the use of hard-coded credentials in the code responsible for encrypting sensitive information stored in the Nexus Repository's configuration database, including SMTP or HTTP proxy credentials and user tokens. The affected versions range from 3.0.0 through 3.72.0.
The CVSS score assigned to this vulnerability is 5.9, indicating a medium severity. This score is crucial as it reflects the potential impact and the urgency for organizations to address the issue promptly. Risk to organizations includes exposure of sensitive data due to reliance on a static hard-coded encryption passphrase. Although administrators can define an alternate passphrase, this must occur at first boot and cannot be updated thereafter.
As of the latest update, there are known exploitation vectors for this vulnerability, emphasizing the necessity for organizations to take immediate action to patch their systems. Organizations should prioritize patching immediately to mitigate the risk of unauthorized access.
The vulnerability was published on October 23, 2024, and has been actively analyzed to identify its implications. Given its nature, organizations leveraging Nexus Repository should assess their configurations and consider immediate remediation actions.
Vulnerability Details
The vulnerability allows for the use of hard-coded credentials, which poses a significant security risk. According to the CVE description, the critical issue lies within the encryption mechanisms employed in the Nexus Repository configuration database, specifically in the code responsible for managing sensitive information. This vulnerability falls under the CWE-798 classification, indicating the use of hard-coded credentials.
The CVSS 3.1 score of 6.5 indicates that while the attack complexity is low, high privileges are required, suggesting that a successful attack would necessitate certain access levels. The confidentiality impact is high, while the integrity and availability impacts are minimal, highlighting that exploitation could lead to significant data exposure.
Given the nature of this vulnerability, organizations using Nexus Repository should assess their current versions and configurations to ensure they are not exposed to potential exploitation.
Technical Analysis
The root cause of this vulnerability can be traced back to the static hard-coded encryption passphrase utilized by the affected Nexus Repository versions. This design flaw allows attackers to bypass the intended security mechanisms, particularly if they can gain local access to the repository system.
Attackers may leverage this vulnerability by exploiting the hard-coded passphrase to decrypt sensitive information stored within the configuration database. The attack vector is classified as local, which means that an attacker must have some level of access to the system hosting the Nexus Repository.
The attack complexity is rated as low, implying that it does not require advanced skills or resources. Importantly, this vulnerability does not require user interaction and grants high confidentiality impact, allowing malicious actors to access sensitive credentials without raising alarms.
In terms of confidentiality impact, the vulnerability could expose sensitive data, including user tokens and proxy credentials, while integrity and availability impacts remain negligible.
Risk & Impact Analysis
This vulnerability poses a significant risk to organizations using Nexus Repository, especially those that handle sensitive information or rely on secure configuration. The risk to organizations includes potential exposure of critical data, leading to unauthorized access and data breaches.
The blast radius for this vulnerability could be extensive, depending on the deployment architecture and the sensitivity of the data stored in the Nexus Repository. Organizations should consider the potential implications of exposing sensitive credentials, which could lead to further attacks or data leaks.
Given the CVSS score of 5.9, organizations should address this vulnerability in priority patch cycles. The absence of an active exploitation status in the KEV catalog indicates that while this vulnerability has been analyzed, it has not yet been reported as actively exploited in the wild.
