CVE-2007-3598
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedindex.php in vtiger CRM before 5.0.3 allows remote authenticated users to obtain all users' names and e-mail addresses, and possibly change user settings, via a modified record parameter in a DetailView action to the Users module. NOTE: the vendor disputes the changing of settings, reporting that the attack vector results in a "You are not permitted to execute this Operation" error message in a 5.0.3 demo.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThis is an Insecure Direct Object Reference (IDOR) vulnerability in vtiger CRM's index.php. Authenticated users can access sensitive information (names and email addresses) of other users by manipulating the 'record' parameter in a DetailView action targeting the Users module. The vulnerability exists because the application does not properly validate whether the authenticated user is authorized to access the requested user record.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify vtiger CRM installation versionLocate the version file in the vtiger installation directory. Common paths include includes/version.php or include/version.php. Open the file and look for a version variable or string that indicates the installed version (such as $vtiger_version or $root_version).Affected if The displayed version number is 5.0.2 or lower.
-
Verify the application is operationalConfirm the vtiger CRM web application is running and accessible by accessing its login page via HTTP/HTTPS (typically at /vtigercrm/ or the root path of the installation).Affected if The application responds and displays a login form, indicating an active vtiger CRM installation.
-
Confirm user authentication is possibleAttempt to log in to the vtiger CRM with any valid user credentials. Verify successful authentication by checking for access to the dashboard or main application interface.Affected if Login succeeds with standard user credentials, granting access to the application.
-
Verify the vulnerable DetailView endpoint existsCheck if the index.php file exists in the vtiger CRM web root and includes a module parameter handling for DetailView actions. The vulnerable URL pattern would be: index.php?module=Users&action=DetailView&record=USERID where USERID is a numeric ID.Affected if The application returns a DetailView page for the Users module without proper authorization errors when accessing another user's record ID.
The environment is affected if vtiger CRM version 5.0.2 or lower is installed and the application allows authenticated users to view other user records via the DetailView action in the Users module by manipulating the record parameter.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade to vtiger CRM version 5.0.3 or later. If upgrading is not immediately feasible, implement proper authorization checks to ensure users can only access their own records in the Users module.
