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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Oracle Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the ELSA-2020-1054 advisory.

    - Resolves: #1599692 - Sanitize input on listinfo page (CVE-2018-0618)

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)

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.
