CVE-2020-37032 is a high-severity OS Command Injection (CWE-78) vulnerability in Wftpserver Wing Ftp Server. Its CVSS base score is 8.6 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 39% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to CM-7 (Least Functionality) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2020-37032 is a remote code execution vulnerability in Wing FTP Server version 6.3.8, specifically within its Lua-based web console. The issue, classified under CWE-78 (OS Command Injection), allows authenticated users to execute arbitrary system commands by sending POST requests with malicious payloads that invoke the os.execute() function, enabling operating system-level code execution.
The vulnerability can be exploited remotely by low-privileged authenticated users (PR:L) with low attack complexity (AC:L) and no user interaction required (UI:N), as indicated by its CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). Successful exploitation provides attackers with high-impact control over confidentiality, integrity, and availability, potentially leading to full server compromise.
Advisories, including those from VulnCheck at https://www.vulncheck.com/advisories/wing-ftp-server-remote-code-execution, document the remote code execution flaw. A public exploit is available at https://www.exploit-db.com/exploits/48676, and the vendor's site is https://www.wftpserver.com/.

Mitigating Controls (NIST 800-53 r5) AI
Requires validation of POST request inputs to the Lua web console, directly preventing OS command injection via malicious payloads invoking os.execute().
Restricts or disables the non-essential Lua-based web console functionality, eliminating the primary attack vector for authenticated remote code execution.
Enforces least privilege to limit web console access to only necessary high-privileged users, mitigating exploitation by low-privileged authenticated attackers.

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.
Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
