CVE-2026-45550 Details
Description
Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. In versions 8.2.6.4 and prior, PUT /smon/check (app/routes/smon/routes.py:117-138) gates only on roxywi_common.check_user_group_for_flask() — which validates that the caller has some group, not that the target check_id belongs to it. The downstream SQL update functions update_smon, update_smonHttp, update_smonTcp, update_smonPing, update_smonDns (app/modules/db/smon.py:515-562) all execute WHERE smon_id = ? with no user_group filter. The DELETE path is correctly filtered (app/modules/db/smon.py:319-327 does WHERE id = ? AND user_group = ?), demonstrating that the maintainers know the right pattern but did not apply it on UPDATE. Therefore any authenticated user can iterate over smon_id values and silently rewrite any other tenant's HTTP / TCP / Ping / DNS monitoring check. At time of publication, there are no publicly available patches.
An Insecure Direct Object Reference (IDOR) vulnerability has been identified in Roxy-WI versions through 8.2.6.4. The issue arises in the 'PUT /smon/check' endpoint, where the application only verifies that the user belongs to a group, without ensuring that the specified 'check_id' is associated with that group. This flaw allows any authenticated user to manipulate monitoring checks of other tenants by updating their HTTP, TCP, Ping, or DNS checks. The vulnerability exists because the SQL update functions for these checks do not include a user group filter, unlike the corresponding DELETE functions, which are properly secured.
Users are advised to update to the patched version of Roxy-WI, which includes the necessary checks to prevent this vulnerability. At the time of publication, no patched version is available.
