Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 23.10 : YARD vulnerabilities (USN-6731-1)

high Nessus Plugin ID 193337

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 23.10 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6731-1 advisory.

 - lib/yard/core_ext/file.rb in the server in YARD before 0.9.11 does not block relative paths with an initial ../ sequence, which allows attackers to conduct directory traversal attacks and read arbitrary files. (CVE-2017-17042)

 - yard before 0.9.20 allows path traversal. (CVE-2019-1020001)

 - YARD is a Ruby Documentation tool. The frames.html file within the Yard Doc's generated documentation is vulnerable to Cross-Site Scripting (XSS) attacks due to inadequate sanitization of user input within the JavaScript segment of the frames.erb template file. This vulnerability is fixed in 0.9.36.
 (CVE-2024-27285)

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

Solution

Update the affected yard package.
