Kerentanan Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') pada gnu mailman, debian linux +4 lainnya. Skor CVSS 3.1 6.1 (Medium) menurut NVD.

Deskripsi (NVD)

GNU Mailman 2.x before 2.1.30 uses the .obj extension for scrubbed application/octet-stream MIME parts. This behavior may contribute to XSS attacks against list-archive visitors, because an HTTP reply from an archive web server may lack a MIME type, and a web browser may perform MIME sniffing, conclude that the MIME type should have been text/html, and execute JavaScript code.
