Summary

CVE-2020-37035 is a high-severity SQL Injection (CWE-89) vulnerability. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 28.0th 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 RA-5 (Vulnerability Monitoring and Scanning) and SI-10 (Information Input Validation).

Deeper analysis

CVE-2020-37035 is a SQL injection vulnerability (CWE-89) affecting e-Learning PHP Script version 0.1.0. The issue exists in the search functionality, where the 'search' parameter processes unvalidated user input, enabling attackers to inject malicious SQL code and manipulate database queries. This flaw has a CVSS v3.1 base score of 8.2 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N), indicating high confidentiality impact with low integrity impact and no availability impact.

Remote attackers require no authentication, privileges, or user interaction to exploit the vulnerability. By submitting crafted SQL payloads through the 'search' parameter, they can extract, modify, or access sensitive database information, potentially compromising user data or other stored records.

Affected Assets

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

prevent

SI-10 directly prevents SQL injection by requiring validation of untrusted inputs like the 'search' parameter to ensure they conform to expected formats and reject malicious SQL code.

prevent

SI-2 requires timely identification, reporting, and correction of flaws like this SQL injection vulnerability through patching or secure code updates.

detect

RA-5 mandates vulnerability scanning and monitoring that would detect the SQL injection vulnerability in the search functionality via automated tools.
