poweradmin/poweradmin
source listedECOSYSTEM: introduced 0; fixed 4.2.4
Description: ### Summary Poweradmin v4.4.0 is vulnerable to CSV Injection (Formula Injection) in its log export functionality. User-controlled data — specifically the username field — is written to exported CSV files without sanitizing formula trigger characters (=, +, -, @). When an administrator exports activity logs and opens the resulting CSV in a spreadsheet application (Microsoft Excel, LibreOffice Calc, Google Sheets), any formula stored in a username is executed by the application. This can be used for phishing attacks against administrators or data exfiltration. ### Details The vulnerability exists in all four log export controllers: - `lib/Application/Controller/ListLogUsersController.php` (lines 188, 194) - `lib/Application/Controller/ListLogZonesController.php` - `lib/Application/Controller/ListLogGroupsController.php` - `lib/Application/Controller/ListLogApiController.php` These controllers export database rows via `fputcsv()` without applying any formula injection countermeasures. The `user` column contains the username of the actor who performed the operation, and the `username` column (in user logs) contains the username of the affected account. Both fields ar

A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
