Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The /admin/delete_judge.php script must be network-accessible to the attacker. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base score of 5.5 reflects a medium-severity finding with low individual-system impact across confidentiality, integrity, and availability (VC:L/VI:L/VA:L), and no lateral scope change (SC:N/SI:N/SA:N). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with network access to the application - requiring no credentials based on the PR:N CVSS vector - sends a crafted HTTP GET or POST request to /admin/delete_judge.php with a judge_id parameter value containing SQL metacharacters or a UNION-based payload. The unsanitized value is interpolated into the DELETE query, allowing the attacker to extract database contents (e.g., credentials, judge records) or corrupt data. … |
| Remediation | No vendor-released patch has been identified at time of analysis - the available references point to a VulDB report (https://vuldb.com/vuln/365547) and an NVD entry (https://nvd.nist.gov/vuln/detail/CVE-2026-9528), neither of which documents a fixed version. … Detailed patch versions, workarounds, and compensating controls in full report. |
