Detailsinfo

A vulnerability was found in haxtheweb haxcms up to 11.0.2 and classified as critical. Affected by this issue is the function gitImportSite of the component HTTP Request Handler. The manipulation of the argument proc_open with an unknown input leads to a os command injection vulnerability. Using CWE to declare the problem leads to CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. CVE summarizes:

HAX CMS PHP allows users to manage their microsite universe with a PHP backend. Prior to version 11.0.3, the `gitImportSite` functionality obtains a URL string from a POST request and insufficiently validates user input. The `set_remote` function later passes this input into `proc_open`, yielding OS command injection. An authenticated attacker can craft a URL string that bypasses the validation checks employed by the `filter_var` and `strpos` functions in order to execute arbitrary OS commands on the backend server. The attacker can exfiltrate command output via an HTTP request. Version 11.0.3 contains a patch for the issue.

The advisory is shared for download at github.com. This vulnerability is handled as CVE-2025-49141 since 06/02/2025. The exploitation is known to be difficult. The attack may be launched remotely.
