Vtiger · Vtiger Crm · CVE-2016-4834
**Name of the Vulnerable Software and Affected Versions**
Vtiger CRM versions 6.4.0 and earlier
**Description**
The issue concerns the `modules/Users/actions/Save.php` file in Vtiger CRM, which does not properly restrict user-save actions. This allows remote authenticated users to create or modify user accounts via unspecified vectors.
**Recommendations**
For versions 6.4.0 and earlier, consider restricting access to the `Save.php` file in the `modules/Users/actions` directory until a patch is available. As a temporary workaround, limit the ability of remote authenticated users to create or modify user accounts to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
