About Roxy-Wi

CVE-2026-33208 affects Roxy-Wi, a product from Roxy-Wi. Before acting, confirm where Roxy-Wi runs in your estate, who owns it and whether it is reachable from the internet, because exposure decides real risk more than the score alone.

What the flaw is

In plain terms: Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. Prior to version 8.2.6.4, the /config/ < service > /find-in-config endpoint in Roxy-WI fails to sanitize the user-supplied words parameter before embedding it into a shell command string that is subsequently executed on a remote managed server via SSH. An authenticated attacker can inject arbitrary shell metacharacters to break out of the intended grep command context and execute arbitrary OS commands with sudo privileges on the target server, resulting in full Remote Code Execution (RCE). Version 8.2.6.4 patches the issue.

The weakness class is OS Command Injection. Untrusted input is passed to the operating system shell, letting an attacker run commands.

Based on its CVSS vector, the flaw can be reached over the network, needs some level of access, and needs no user interaction. Apply the vendor fix and confirm exposure on internet facing and business critical assets first.

How to detect it

  • Inventory every instance of Roxy-Wi and record the running version against the affected range above.
  • Check external attack surface scans for internet facing instances of the component.
  • Review logs on affected systems for unusual requests, errors or new processes around the vulnerable function.
  • Confirm with an authenticated vulnerability scan once your scanner has a check for this CVE.

How to fix it

  • Apply the fixed version of Roxy-Wi named in the vendor advisory.
  • If patching must wait, restrict network access to the affected service and put it behind authentication or a web application firewall rule.
  • Rescan after the change to prove the exposure is gone, then close the ticket.

CVE-2026-33078
Roxy-Wi

Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. Versions prior to 8.2.6.4 have a SQL injection vulnerability in the haproxy_section_save function in app/routes/config/routes.py. The server_ip parameter, sourced from the URL path, is passed unsanitized through multiple function calls and ultimately interpolated into a SQL query string using Python string formatting, allowing attackers to execute arbitrary SQL commands. Version 8.2.6.4 fixes the issue.

Roxy-Wi

Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. Prior to version 8.2.6.4, the haproxy_section_save interface presents a vulnerability that could lead to remote code execution due to path traversal and writing into scheduled tasks. Version 8.2.6.4 fixes the issue.

CVE-2026-33432
Roxy-Wi

Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. In versions up to and including 8.2.8.2, when LDAP authentication is enabled, Roxy-WI constructs an LDAP search filter by directly concatenating the user-supplied login username into the filter string without escaping LDAP special characters. An unauthenticated attacker can inject LDAP filter metacharacters into the username field to manipulate the search query, cause the directory to return an unintended user entry, and bypass authentication entirely — gaining access to the application without knowing any valid password. As of time of publication, no known patches are available.
