Summary

CVE-2026-3692 is a high-severity OS Command Injection (CWE-78) vulnerability in Progress Flowmon. Its CVSS base score is 8.7 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked at the 35th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2026-3692 is a command injection vulnerability (CWE-78) affecting Progress Flowmon versions prior to 12.5.8. It occurs during the report generation process, where an authenticated low-privileged user can craft a malicious request that causes unintended commands to be executed on the server. The vulnerability has a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for complete server compromise.

An attacker with low-privileged authenticated access to the Flowmon system can exploit this vulnerability remotely over the network with low complexity and no user interaction required. By crafting a specially designed request during report generation, the attacker can execute arbitrary commands on the underlying server, potentially leading to high-impact confidentiality, integrity, and availability violations, such as data exfiltration, modification, or denial of service.

The Progress advisory at https://community.progress.com/s/article/CVE-2026-3692-Progress-Flowmon recommends upgrading to Flowmon version 12.5.8 or later to mitigate the vulnerability.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover missing or incorrect command sanitization during development.

Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.

Least privilege reduces the permissions available to any process that could be subverted by injected commands.

Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.

Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06 mostly match

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.

PR.PS-02 partial match

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).
