Summary

CVE-2020-37076 is a high-severity SQL Injection (CWE-89) vulnerability in Victor Cms Project Victor Cms. Its CVSS base score is 8.2 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 32.0th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-11 (Error Handling).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190) and 1 other technique. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly prevents SQL injection in the 'post' parameter of post.php by validating inputs against malicious UNION SELECT payloads and injection techniques.

SI-11 Error Handling partial match

prevent

Mitigates error-based SQL injection exploitation by suppressing database error messages that reveal structure for further attacks.

SI-15 Information Output Filtering partial match

prevent

Filters outputs from post.php to block exfiltration of sensitive database information via successful boolean-based or time-based injections.
