AI-suggested
1. Upgrade Nexus Repository to a version beyond 2.15.2 once Sonatype releases a patch addressing CVE-2025-9868. 2. Until a patch is available, disable or restrict access to the Remote Browser Plugin to prevent exploitation. 3. Implement strict network segmentation and firewall rules to limit outbound HTTP requests from the Nexus Repository server, reducing the ability to exfiltrate data. 4. Monitor network traffic for unusual or unauthorized outbound requests originating from Nexus Repository instances. 5. Audit and rotate proxy repository credentials regularly to minimize the impact of potential credential exposure. 6. Employ Web Application Firewalls (WAFs) with rules to detect and block SSRF attack patterns targeting Nexus Repository. 7. Conduct security awareness and incident response drills focusing on supply chain compromise scenarios. 8. Review and harden access controls around artifact repositories and related infrastructure to limit lateral movement opportunities.
Description
Server-Side Request Forgery (SSRF) in the Remote Browser Plugin in Sonatype Nexus Repository 2.x up to and including 2.15.2 allows unauthenticated remote attackers to exfiltrate proxy repository credentials via crafted HTTP requests.
