CVE-2013-3082

An attacker can trigger this vulnerability by sending a crafted request to the forgot-password/ endpoint. By injecting malicious web script or HTML into the search parameter, the attacker forces the application to reflect the payload back to the user's browser within an error message. This allows for the execution of arbitrary scripts in the context of the victim's session [CWE-79].

The vulnerability is located in the plugins/jojo_core/forgot_password.php file. Specifically, the issue occurs within the _getContent() function where the $search variable is directly concatenated into an error message string.

The patch modifies plugins/jojo_core/forgot_password.php to wrap the $search variable in the htmlentities() function before it is included in the error message [patch_id=4373310]. This ensures that any special characters provided by the user are converted into their corresponding HTML entities, preventing the browser from interpreting the input as executable code. This effectively neutralizes the cross-site scripting vector by ensuring the input is treated as plain text.

The vulnerability can be reproduced by navigating to the forgot-password/ page and submitting a search query containing HTML or JavaScript payloads, which will then be reflected in the resulting error message.
