Vulnerability AssessmentAI
| Exploitation | No authentication is required - the PHPRPC Remote Call Interface endpoint is publicly accessible without credentials, confirmed by PR:N in the CVSS 4.0 vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base score of 5.5 (Medium) reflects Low impact across all three pillars (VC:L/VI:L/VA:L) with no subsequent-system scope change. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An unauthenticated external attacker identifies an internet-exposed MetaCRM instance and sends a crafted HTTP request to `/customizemt/xkq/rpc.jsp` with a SQL injection payload embedded in the `phprpc_args` parameter targeting the `RPCService.query` function. The unsanitized argument is interpreted directly by the database engine, allowing the attacker to enumerate schema, extract customer records or credentials, or modify database contents. … |
| Remediation | No vendor-released patch has been identified at time of analysis - the vendor (Metasoft) did not respond to coordinated disclosure, and no fix version exists to cite. … Detailed patch versions, workarounds, and compensating controls in full report. |
