Test ID:1.3.6.1.4.1.25623.1.0.143773
Category:Web application abuses
Title:Mailman 2.x < 2.1.30 XSS Vulnerability
Summary:Mailman is prone to a cross-site scripting (XSS); vulnerability.
Description:Summary:
Mailman is prone to a cross-site scripting (XSS)
vulnerability.

Vulnerability Insight:
GNU Mailman 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.

Affected Software/OS:
GNU Mailman versions 2.0.0 through 2.1.29.

Solution:
Update to version 2.1.30 or later.

CVSS Score:
4.3

CVSS Vector:
AV:N/AC:M/Au:N/C:N/I:P/A:N
