description

Checkmk Setup in-page search mishandles a URL parameter in affected releases. An attacker may cause script execution in an authenticated Setup user's session or send that user to an external site if the user opens an attacker-controlled link and triggers the relevant search action.

mitigation

Upgrade Checkmk to 2.5.0p15, 2.4.0p38, or 2.3.0p51 or later in the corresponding supported branch. Move installations on the end-of-life 2.2.0 line to a supported, patched release.

fixed in 2.5.0p15, 2.4.0p38, 2.3.0p51
