Debian LTS Advisory DLA-3049-1 [email protected]
https://www.debian.org/lts/security/ Sylvain Beucler

Package : mailman
Version : 1:2.1.23-1+deb9u8
CVE ID : CVE-2021-43331 CVE-2021-43332 CVE-2021-44227
Debian Bug : 1000367 1001685
Several vulnerabilities were discovered in Mailman, a web-based
mailing list manager. An attacker could impersonate more privileged
accounts through different vectors.
CVE-2021-43331
A crafted URL to the Cgi/options.py user options page can execute
arbitrary JavaScript for XSS. (Closes: #1000367)
CVE-2021-43332
The CSRF token for the Cgi/admindb.py admindb page contains an
encrypted version of the list admin password. This could
potentially be cracked by a moderator via an offline brute-force
attack.
CVE-2021-44227
A list member or moderator can get a CSRF token and craft an admin
request (using that token) to set a new admin password or make
other changes.
For Debian 9 stretch, these problems have been fixed in version
1:2.1.23-1+deb9u8.
We recommend that you upgrade your mailman packages.
