Summary

CVE-2020-37033 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 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Deeper analysis

CVE-2020-37033 is a SQL injection vulnerability (CWE-89) in Infor Storefront B2B 1.0. The flaw resides in the 'usr_name' parameter used in login requests, where insufficient input validation allows attackers to inject malicious SQL code and manipulate underlying database queries.

The vulnerability carries 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 it is exploitable remotely with low complexity, no authentication privileges, and no user interaction required. Attackers can submit crafted inputs via the 'usr_name' parameter to extract sensitive database information or perform limited modifications, potentially compromising confidentiality and integrity.

Advisories and related resources include a VulnCheck entry detailing the Infor Storefront B2B 'usr_name' SQL injection, an Exploit-DB proof-of-concept (ID 48674), and an archived Infor Storefront product page. No specific patch or mitigation guidance is detailed in the provided references.

A public exploit is available on Exploit-DB, indicating proof-of-concept exploitation capability. The CVE was published on 2026-01-30.

Affected Assets

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly prevents SQL injection by validating and sanitizing the 'usr_name' parameter to block malicious SQL code in login requests.

SI-9 Information Input Restrictions partial match
prevent

Restricts input types, lengths, and formats for parameters like 'usr_name' to block common SQL injection payloads.

SI-2 Flaw Remediation good match
prevent

Remediates the specific SQL injection flaw in the login functionality through timely identification and correction of the vulnerable code.
