Summary

CVE-2026-3692 is a high-severity OS Command Injection (CWE-78) vulnerability in Progress Flowmon. 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 40.5th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190) and 2 other techniques. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Directly mitigates the CVE by identifying, reporting, and correcting the command injection flaw through timely patching or upgrading to Flowmon 12.5.8 or later.

SI-10 Information Input Validation good match

prevent

Enforces input validation at the report generation interface to block crafted malicious requests that inject and execute unintended commands.

AC-6 Least Privilege partial match

prevent

Limits the impact of command injection by ensuring low-privileged users and processes have only necessary privileges to execute server commands.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

attack.mitre.org →

T1059 Command and Scripting Interpreter Execution

Adversaries may abuse command and script interpreters to execute commands, scripts, or binaries.

attack.mitre.org →

T1068 Exploitation for Privilege Escalation Privilege Escalation

Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.

attack.mitre.org →

Why these techniques?

Command injection in report generation enables exploitation of public-facing application (T1190) for remote code execution via command interpreter (T1059) and privilege escalation from low-priv to server compromise (T1068).

NVD Description

In Progress Flowmon versions prior to 12.5.8, a vulnerability exists whereby an authenticated low-privileged user may craft a request during the report generation process that results in unintended commands being executed on the server.

Deeper analysisAI

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.
