Vulnerability AssessmentAI
| Exploitation | Requires a valid authenticated session on Flowring Agentflow 4.0 (PR:L, low privilege sufficient) and network access to the /WebAgenda/download/uploadFile.jsp endpoint; exploitation is performed by supplying directory-traversal sequences in the 'path' parameter. … 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:L/UI:N/VC:N/VI:H/VA:N, base 7.1) describes a remotely reachable, low-complexity path-traversal that requires an authenticated but low-privilege account (PR:L) and no user interaction. … 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 | Vendor-released patch: update to a Flowring Agentflow 4.0 version released on or after 2023/03/24. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
For Flowring Agentflow 4.0 instances released before March 24, 2023, immediately restrict access to the /WebAgenda/download/uploadFile.jsp endpoint via network controls or WAF rules within 24 hours, and enable detailed logging for file upload activities. …
