Severity by source
AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Network-exposed endpoint requires no authentication; path traversal yields read-only file access, justifying C:H with I:N and A:N.

In DocSys-master V2.02.85, the downloadDocEx interface in src/com/DocSystem/controller/DocController.java has an arbitrary file read vulnerability:
AnalysisAI
Arbitrary file read via path traversal in DocSys-master V2.02.85 exposes the server filesystem to unauthenticated remote attackers through the downloadDocEx endpoint in DocController.java, which fails to sanitize user-supplied path parameters. Publicly available exploit code exists per SSVC poc status and the GitHub reference. …

Vulnerability AssessmentAI
| Exploitation | No authentication is required - the CVSS vector PR:N confirms unauthenticated access. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) characterizes this as unauthenticated, low-complexity, remotely exploitable with high confidentiality impact - a severe attack surface on paper. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An unauthenticated remote attacker sends an HTTP request to the publicly accessible downloadDocEx endpoint with a crafted filename parameter such as '../../../../etc/passwd' or '../../../../WEB-INF/web.xml'. The server, lacking path validation, reads and returns the file contents directly. … |
| Remediation | No vendor-released patch identified at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all DocSys V2.02.85 instances deployed in your environment and apply network-level restrictions via firewall or WAF rules limiting access to the downloadDocEx endpoint to authorized users and networks only. …
