CVE-2026-4591 Details
Description
A weakness has been identified in kalcaddle kodbox 1.64. This affects the function checkBin of the file /workspace/source-code/plugins/fileThumb/app.php of the component fileThumb Endpoint. Executing a manipulation can lead to os command injection. The attack can be executed remotely. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
A command injection vulnerability has been identified in Kalcaddle Kodbox version 1.64, specifically within the FileThumb plugin. The issue arises in the 'checkBin' function of 'app.php', where the application improperly sanitizes input before passing it to 'shell_exec'. This flaw allows authenticated administrators to manipulate configuration values with shell metacharacters, executing arbitrary commands on the server with the web server's privileges.
It is recommended to remove unsafe concatenation of shell commands, implement strict whitelisting of allowed binaries and paths, use non-shell process execution methods with validated arguments, and review and tighten configuration permissions.
