Threat & Defense Details

Likely Mitigating ControlsAI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

SC-27 Platform-independent Applications

addresses: CWE-78

Platform-independent apps typically execute inside a managed runtime or sandbox that restricts direct OS command execution, reducing the ability to exploit OS command injection.

SI-10 Information Input Validation

addresses: CWE-78

Validates inputs to block special elements that would alter OS command execution.

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 →

T1059.004 Unix Shell Execution

Adversaries may abuse Unix shell commands and scripts for execution.

attack.mitre.org →

Why these techniques?

Command injection in public-facing web management interface directly enables remote exploitation (T1190) and arbitrary Unix shell command execution (T1059.004).

NVD Description

Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. Prior to 8.2.8.2, command injection vulnerability exists in the log viewing functionality that allows authenticated users to execute arbitrary system commands. The vulnerability is in app/modules/roxywi/logs.py line…

87, where the grep parameter is used twice - once sanitized and once raw. This vulnerability is fixed in 8.2.8.2.

Deeper analysisAI

CVE-2026-22265 is a command injection vulnerability in Roxy-WI, a web interface for managing HAProxy, Nginx, Apache, and Keepalived servers. Affecting versions prior to 8.2.8.2, the flaw resides in the log viewing functionality at app/modules/roxywi/logs.py line 87, where the grep parameter is processed twice—once in a sanitized manner and once raw—allowing injection of arbitrary system commands. Classified under CWE-78 with a CVSS v3.1 base score of 7.5 (AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H), it was published on January 15, 2026.

Authenticated users with low privileges (PR:L) can exploit this vulnerability remotely over the network without user interaction. By crafting malicious input for the grep parameter during log viewing, attackers gain the ability to execute arbitrary system commands on the underlying host, potentially leading to high-impact confidentiality, integrity, and availability compromises, such as data exfiltration, modification, or denial of service.

The vulnerability is addressed in Roxy-WI version 8.2.8.2, as detailed in the project's GitHub security advisory (GHSA-mmmf-vh7m-rm47), release notes, and the fixing commit (f040d3338c4ba6f66127487361592e32e0188eee). Security practitioners should upgrade to the patched version and review access controls for authenticated users interacting with log viewing features.
