Low risk14th percentile — higher than 14% of all known CVEs
Summary
Poweradmin before versions 4.2.4 and 4.3.3 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 (=, +, -, @).
Risk Assessment
When an administrator opens the exported CSV file in a spreadsheet application (Excel, LibreOffice Calc, Google Sheets), a formula stored in a username may be executed, enabling phishing attacks or data exfiltration.
Recommendation
Update Poweradmin to version 4.2.4 or 4.3.3 immediately, which patch this vulnerability.
Original NVD description (English source)
Poweradmin is a web-based DNS administration tool for PowerDNS server. Versions prior to 4.2.4 and 4.3.3 are 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. Versions 4.2.4 and 4.3.3 patch the issue.
