What to do
AI-suggested
- Immediate mitigation includes educating users to avoid opening CSV files from untrusted or unexpected sources, especially those exported from Koha's affected endpoints.
- Configure spreadsheet applications to disable automatic formula execution or DDE functionality where possible. For example, in Microsoft Excel, disable 'Update Links to other documents' and disable DDE execution via Group Policy or application settings.
- Implement input validation and sanitization on the server side to neutralize any formula injection attempts by escaping or removing leading characters ('=', '+', '-', '@') in CSV export fields.
- Monitor and restrict access to the vulnerable endpoints to trusted personnel only, and audit CSV export logs for unusual activity.
- Apply any forthcoming official patches from Koha promptly once available.
- Consider using alternative export formats (e.g., PDF or sanitized text files) for sensitive data until the vulnerability is resolved.
- Employ endpoint protection solutions capable of detecting and blocking suspicious script execution triggered by spreadsheet applications.
Description
CSV Injection vulnerability in '/members/moremember.pl' and '/admin/aqbudgets.pl' endpoints in Koha Library Management System version 23.05.05 and earlier allows attackers to to inject DDE commands into csv exports via the 'Budget' and 'Patrons Member' components.
