Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires network access to the `/edit_class.php` endpoint and the ability to supply arbitrary values to the `ID` parameter - no authentication, no user interaction, and no special server configuration is needed per the CVSS 4.0 vector (PR:N, UI:N, AC:L, AT:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 6.9 (Medium) reflects an accessible, unauthenticated attack vector (AV:N/AC:L/AT:N/PR:N/UI:N) with low partial impact across confidentiality, integrity, and availability (VC:L/VI:L/VA:L). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An unauthenticated attacker sends a crafted HTTP GET or POST request to `/edit_class.php?id=1 UNION SELECT username,password,3 FROM users--`, injecting a malicious SQL payload via the `ID` parameter and causing the backend database to return sensitive records such as administrator credentials or student data. A public proof-of-concept is available on GitHub (https://github.com/yuanyuandechen/vul/issues/2), reducing the skill barrier to near zero. … |
| Remediation | No vendor-released patch has been identified at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
