**Name of the Vulnerable Software and Affected Versions** IBOS OA version 4.5.5 **Description** A critical issue was found in the function `actionExport` of the component Personal Office Address Book, specifically in the file "?r=contact/default/export". This issue leads to SQL injection and can be exploited remotely. **Recommendations** For IBOS OA version 4.5.5, as a temporary workaround, consider disabling the `actionExport` function until a patch is available. Restrict access to the file "?r=contact/default/export" to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this issue.
