GNU Mailman before 2.1.35 may allow remote Privilege Escalation. A csrf_token value is not specific to a single user account. An attacker can obtain a value within the context of an unprivileged user account, and then use that value in a CSRF attack against an admin (e.g., for account takeover).

According to the versions of the mailman package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Cross-site request forgery (CSRF) vulnerability in the user options page in GNU Mailman 2.1.x before     2.1.23 allows remote attackers to hijack the authentication of arbitrary users for requests that modify an     option, as demonstrated by gaining access to the credentials of a victim's account. (CVE-2016-6893)

  - GNU Mailman before 2.1.35 may allow remote Privilege Escalation. A certain csrf_token value is derived     from the admin password, and may be useful in conducting a brute-force attack against that password.
