The remote Redhat Enterprise Linux 8 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2021:4916 advisory.

    Mailman is a program used to help manage e-mail discussion lists.

    Security Fix(es):

    * mailman: CSRF token bypass allows to perform CSRF attacks and admin takeover (CVE-2021-44227)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and     other related information, refer to the CVE page(s) listed in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

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

  - In GNU Mailman before 2.1.36, a crafted URL to the Cgi/options.py user options page can execute arbitrary     JavaScript for XSS. (CVE-2021-43331)

  - In GNU Mailman before 2.1.36, 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-2021-43332)

  - In GNU Mailman before 2.1.38, 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. (CVE-2021-44227)

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

The remote SUSE Linux SLES12 / SLES_SAP12 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:1886-1 advisory.

  - 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.
    (CVE-2021-42096)

  - In GNU Mailman before 2.1.36, a crafted URL to the Cgi/options.py user options page can execute arbitrary     JavaScript for XSS. (CVE-2021-43331)

  - In GNU Mailman before 2.1.36, 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-2021-43332)

  - In GNU Mailman before 2.1.38, 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. (CVE-2021-44227)

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

The remote Debian 9 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-3049 advisory.

  - In GNU Mailman before 2.1.36, a crafted URL to the Cgi/options.py user options page can execute arbitrary     JavaScript for XSS. (CVE-2021-43331)

  - In GNU Mailman before 2.1.36, 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-2021-43332)

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

The remote Scientific Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the SLSA-2021:4913-1 advisory.

  - mailman: CSRF token bypass allows to perform CSRF attacks and account takeover (CVE-2021-42097)

  - mailman: CSRF token bypass allows to perform CSRF attacks and admin takeover (CVE-2021-44227)

  - mailman: CSRF protection missing in the user options page (CVE-2016-6893)

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

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.
    (CVE-2021-42096)

  - 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). (CVE-2021-42097)

  - In GNU Mailman before 2.1.38, 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. (CVE-2021-44227)
