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.

 It was discovered that 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. This issue only affected Ubuntu 16.04 LTS. (CVE-2017-17042)

 It was discovered that yard before 0.9.20 is affected by a path traversal vulnerability, allowing HTTP requests to access arbitrary files under certain conditions. This issue only affected Ubuntu 18.04 LTS.
 (CVE-2019-1020001)

 Aviv Keller discovered that 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. (CVE-2024-27285)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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.
