Mark Sapiro reports :

Existing protections against malicious listowners injecting evil scripts into listinfo pages have had a few more checks added.

A few more error messages have had their values HTML escaped.

The hash generated when SUBSCRIBE_FORM_SECRET is set could have been the same as one generated at the same time for a different list and IP address.

The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has mailman packages installed that are affected by multiple vulnerabilities:

  - An issue was discovered in GNU Mailman before 2.1.28. A crafted URL can cause arbitrary text to be     displayed on a web page from a trusted site. (CVE-2018-13796)

  - Cross-site scripting vulnerability in Mailman 2.1.26 and earlier allows remote authenticated attackers to     inject arbitrary web script or HTML via unspecified vectors. (CVE-2018-0618)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote host is affected by the vulnerability described in GLSA-201904-10 (Mailman: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Mailman. Please review       the referenced CVE identifier for details.
  Impact :

    Please review the referenced CVE identifiers for details.
  Workaround :

    There is no known workaround at this time.

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

  - Cross-site scripting vulnerability in Mailman 2.1.26     and earlier allows remote authenticated attackers to     inject arbitrary web script or HTML via unspecified     vectors.(CVE-2018-0618)

  - An issue was discovered in GNU Mailman before 2.1.28. A     crafted URL can cause arbitrary text to be displayed on     a web page from a trusted site.(CVE-2018-13796)

  - /options/mailman in GNU Mailman before 2.1.31 allows     Arbitrary Content Injection.(CVE-2020-12108)

  - 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.(CVE-2020-12137)

  - GNU Mailman before 2.1.33 allows arbitrary content     injection via the Cgi/private.py private archive login     page.(CVE-2020-15011)

The version of mailman installed on the remote host is prior to 2.1.15-30.25. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2020-1395 advisory.

    Cross-site scripting vulnerability in Mailman 2.1.26 and earlier allows remote authenticated attackers to     inject arbitrary web script or HTML via unspecified vectors. (CVE-2018-0618)

This update for mailman to version 2.1.27 fixes the following issues :

This security issue was fixed :

  - CVE-2018-0618: Additional protections against injecting     scripts into listinfo and error messages pages     (bsc#1099510).

These non-security issues were fixed :

  - The hash generated when SUBSCRIBE_FORM_SECRET is set     could have been the same as one generated at the same     time for a different list and IP address.

  - An option has been added to bin/add_members to issue     invitations instead of immediately adding members.

  - A new BLOCK_SPAMHAUS_LISTED_IP_SUBSCRIBE setting has     been added to enable blocking web subscribes from IPv4     addresses listed in Spamhaus SBL, CSS or XBL. It will     work with IPv6 addresses if Python's py2-ipaddress     module is installed. The module can be installed via pip     if not included in your Python.

  - Mailman has a new 'security' log and logs authentication     failures to the various web CGI functions. The logged     data include the remote IP and can be used to automate     blocking of IPs with something like fail2ban. Since     Mailman 2.1.14, these have returned an http 401 status     and the information should be logged by the web server,     but this new log makes that more convenient. Also, the     'mischief' log entries for 'hostile listname' noe     include the remote IP if available.

  - admin notices of (un)subscribes now may give the source     of the action. This consists of a %(whence)s replacement     that has been added to the admin(un)subscribeack.txt     templates. Thanks to Yasuhito FUTATSUKI for updating the     non-English templates and help with internationalizing     the reasons.

  - there is a new BLOCK_SPAMHAUS_LISTED_DBL_SUBSCRIBE     setting to enable blocking web subscribes for addresses     in domains listed in the Spamhaus DBL.

Toshitsugu Yoneyama of Mitsui Bussan Secure Directions, Inc.
discovered that mailman, a web-based mailing list manager, is prone to a cross-site scripting flaw allowing a malicious listowner to inject scripts into the listinfo page, due to not validated input in the host_name field.
