Description

It was discovered that the Mailman administrative web interface did not protect against cross-site request forgery (CSRF) attacks. If an authenticated user were tricked into visiting a malicious website while logged into Mailman, a remote attacker could perform administrative actions. This issue only affected Ubuntu 12.04 LTS. (CVE-2016-7123)

Nishant Agarwala discovered that the Mailman user options page did not protect against cross-site request forgery (CSRF) attacks. If an authenticated user were tricked into visiting a malicious website while logged into Mailman, a remote attacker could modify user options. (CVE-2016-6893).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
