Path Traversal in Sonatype Nexus Repository 3
CVE-2024-4956 is a path-traversal vulnerability in Sonatype Nexus Repository 3 that permits an unauthenticated attacker to read system files. The issue is fixed in Nexus Repository version 3.68.1.
What it means and what to do now: patch path, interim mitigations, and the assume-compromise checklist.
What an attacker gets, and what they’ve been doing with it.
Successful exploitation exposes system files accessible to the Nexus Repository process, potentially disclosing sensitive configuration, credential, or other host-resident data depending on file permissions and deployment configuration.
If you can’t patch tonight, do this now.
Until the fixed version is deployed, restrict access to Nexus Repository management and HTTP endpoints to trusted networks and authenticated reverse proxies or VPN users. Monitor web access logs for traversal-style requests and investigate unexpected file-read responses. Apply least-privilege filesystem permissions to the Nexus service account to limit the sensitivity of files it can read.
Patch, then assume compromise.
Upgrade Sonatype Nexus Repository 3 to version 3.68.1 or a later version containing the fix.
