Vulnerability AssessmentAI
| Exploitation | The attacker must be able to reach the DocSys web application's file-upload function over the network and upload a server-executable file type (e.g. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The raw signals are severe on paper: the CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N, C:H/I:H/A:H) describes trivial remote exploitation yielding full system compromise, and a public POC write-up lowers the barrier to weaponization. … 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 or fixed version is identified in the available data - the only vendor reference is an open GitHub issue (issues/49), not a tagged release, so upgrade guidance cannot cite a confirmed fixed build; monitor the RainyGao DocSys repository for a patched tag. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Identify and inventory all RainyGao DocSys 2.02.80 instances; immediately implement network-level access restrictions (firewall rules, VPN requirement, or IP whitelist) limiting connectivity to administrative users only. …
