POC and Scanner for CVE-2023-24055

Use at your own risk!

A simple Parser for the KeePass config file running unter Windows. The tool will open the directory %APPDATA%\Roaming\KeePass\KeePass.config.xml and will output all triggers. The triggers

• Execute command line / URL
• Synchronize active database with a file/URL
• Export active database

are marked as dangerous. This is my personal opinion, I am sure you can perform malicious stuff with some other actions, too!

Hint: If you do not recognize some of the triggers, check them carefully!

Proof of Concept code for CVE-2023-24055

The tool will open the directory %APPDATA%\Roaming\KeePass\KeePass.config.xml and will add a trigger to the KeePass config so that the current database gets exportet to c:\Users\%USERNAME%\KeepassExport.csv when it is opened.

The parameter ExportNoKey is set to TRUE so that KeePass will not ask for the master password during export.

• Add feature to config_scanner to read arbitrary config files provides by the commandline
