Description Preview
CVE-2020-10199 affects Sonatype Nexus Repository Manager versions before 3.21.2. The vulnerability allows attackers to execute arbitrary code via JavaEL Injection. This is classified as CWE-917 (Expression Language Injection), which occurs when the software constructs all or part of an expression language (EL) statement using externally-influenced input and does not neutralize special elements that could modify the intended EL statement.
Overview
This vulnerability in Sonatype Nexus Repository Manager allows remote attackers to execute arbitrary code on the affected system by exploiting a JavaEL Injection vulnerability. The issue affects the administrative interface of Nexus Repository Manager and can be exploited by authenticated users with administrative privileges. Successful exploitation could lead to complete system compromise, allowing attackers to execute commands with the same privileges as the application server running Nexus Repository Manager. This is a critical vulnerability that should be addressed immediately in affected deployments.
Remediation
- Update Sonatype Nexus Repository Manager to version 3.21.2 or later, which contains the fix for this vulnerability.
- If immediate updating is not possible, implement the following mitigations:
- Restrict access to the Nexus Repository Manager administrative interface
- Implement network segmentation to limit exposure of the Nexus server
- Monitor logs for suspicious activity that might indicate exploitation attempts
- Review user permissions and ensure that only trusted users have administrative access
- Consider implementing a web application firewall (WAF) to help detect and block exploitation attempts
