AI-analyzed exploit summary This exploit demonstrates a command injection vulnerability in the 'is-human' WordPress plugin (version 1.4.2 and prior) by manipulating the 'type' parameter in the 'engine.php' file when the 'action' is set to 'log-reset'. The exploit uses the 'passthru' function to execute arbitrary commands.

Description

The WordPress plugin is-human <= v1.4.2 contains an eval injection vulnerability in /is-human/engine.php that can be triggered via the 'type' parameter when the 'action' parameter is set to 'log-reset'. The root cause is unsafe use of eval() on user-controlled input, which can lead to execution of attacker-supplied PHP and OS commands. This may result in arbitrary code execution as the webserver user, site compromise, or data exfiltration. The is-human plugin was made defunct in June 2008 and is no longer available for download. This vulnerability was exploited in the wild in March 2012.
