Lifecycle Timeline
1DescriptionCVE.org
A flaw has been found in restify node-restify up to 12.0.0. This affects the function serveStatic in the library /lib/plugins/static.js. This manipulation causes path traversal. The attack can be initiated remotely. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
Path traversal in node-restify's serveStatic plugin exposes arbitrary server-side files to unauthenticated remote attackers on all versions up to and including 12.0.0. The serveStatic function in /lib/plugins/static.js fails to adequately sanitize user-controlled path segments, allowing traversal sequences to escape the intended static file root and return files from elsewhere on the filesystem. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the target restify application is at version 12.0.0 or earlier AND is configured to invoke the serveStatic plugin on at least one route - applications that do not use serveStatic are unaffected by this specific flaw. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N) confirms fully unauthenticated, low-complexity remote exploitation with no user interaction required. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch has been identified at time of analysis - the maintainer did not respond to disclosure outreach. … Detailed patch versions, workarounds, and compensating controls in full report. |
Threat intelligence, references, and detailed analysis are available after sign-in.
