Detailsinfo

A vulnerability, which was classified as problematic, has been found in Poweradmin up to 4.2.3/4.3.2. Affected by this issue is some unknown processing of the component CSV File Handler. The manipulation of the argument username with an unknown input leads to a csv injection vulnerability. Using CWE to declare the problem leads to CWE-1236. The product saves user-provided information into a Comma-Separated Value (CSV) file, but it does not neutralize or incorrectly neutralizes special elements that could be interpreted as a command when the file is opened by a spreadsheet product. Impacted is confidentiality, integrity, and availability. CVE summarizes:

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.
