high Nessus Plugin ID 183127

Language:

Synopsis

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

Description

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 ESM host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5271-1 advisory.

 It was discovered that Adminer did not escape data in the history parameter of the default URI. A remote attacker could possibly use this issue to perform cross-site scripting (XSS) attacks. This issue only affected Ubuntu 20.04 ESM. (CVE-2020-35572)

 Adam Crosser and Brian Sizemore discovered that Adminer incorrectly handled redirection requests to internal servers. An unauthenticated remote attacker could possibly use this to perform a server-side request forgery attack and expose sensitive information. (CVE-2021-21311)

 It was discovered that Adminer was incorrectly escaping data in the doc_link function. A remote attacker could possibly use this issue to perform cross-site scripting (XSS) attacks. This issue only affected Ubuntu 18.04 ESM and Ubuntu 20.04 ESM. (CVE-2021-29625)

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 adminer package.
