Vulnerability AssessmentAI
| Exploitation | The /manage/resourceUpload/upload.do endpoint must be network-reachable by the attacker. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base score of 6.9 with E:P (proof-of-concept) modifier reflects a network-accessible, unauthenticated, zero-complexity attack with low recorded impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An unauthenticated attacker sends a crafted HTTP POST request to /manage/resourceUpload/upload.do on an internet-exposed or network-reachable e-Face platform, uploading a JSP or other server-side script disguised or simply named with an executable extension. A publicly available POC (documented at the Feishu reference) demonstrates this technique. … |
| Remediation | No vendor-released patch or advisory has been identified at time of analysis; no fix version is confirmed in the available data. … Detailed patch versions, workarounds, and compensating controls in full report. |
