Associated Vulnerability

Title:Users enumeration allowed through Rest API in Combodo iTop (CVE-2024-51739)
Description:Combodo iTop is a simple, web based IT Service Management tool. Unauthenticated user can perform users enumeration, which can make it easier to bruteforce a valid account. As a fix the sentence displayed after resetting password no longer shows if the user exists or not. This fix is included in versions 2.7.11, 3.0.5, 3.1.2, and 3.2.0. Users are advised to upgrade. Users unable to upgrade may overload the dictionary entry `"UI:ResetPwd-Error-WrongLogin"` through an extension and replace it with a generic message.

Description

From the webservices/rest.php file, several operations are accessible from an unauthenticated user. One of them is `do_reset_pwd`, allowing to reset a user password. This feature can be abused to perform user enumeration when a non-existent user is provided.
