CVE-2020-37141
Published: 07 February 2026
Summary
CVE-2020-37141 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 20.4th 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-2020-37141 is a SQL injection vulnerability (CWE-89) in AMSS++ version 4.31. The flaw exists in the mail module's maildetail.php script, accessible via the /modules/mail/main/maildetail.php endpoint, where the 'id' parameter fails to properly sanitize input. This allows attackers to inject malicious SQL queries, potentially enabling unauthorized access or modification of database contents. 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 high severity due to network accessibility and significant confidentiality impact.
Unauthenticated attackers can exploit this vulnerability remotely over the network with low attack complexity and no user interaction required. By manipulating the 'id' parameter in requests to maildetail.php, they can execute arbitrary SQL queries, achieving high confidentiality impact such as dumping sensitive database information and low integrity impact like altering limited data, while availability remains unaffected.
Advisories and related resources, including a proof-of-concept exploit, are documented at https://www.exploit-db.com/exploits/48109 and https://www.vulncheck.com/advisories/amss-v-id-sql-injection. These references provide further details on exploitation and potential mitigations, such as applying patches if available or implementing input validation and prepared statements in the affected component.

Mitigating Controls (NIST 800-53 r5) AI
Directly mitigates the SQL injection vulnerability by requiring validation and sanitization of the unsanitized 'id' parameter in maildetail.php to block malicious queries.
Addresses the root cause by mandating timely flaw remediation, such as patching the SQL injection in AMSS++ version 4.31 or implementing prepared statements.
Complements input validation by restricting the 'id' parameter to organization-defined allowable formats and values, preventing injection of SQL payloads.
