Adminer is open-source database management software. A cross-site scripting vulnerability in Adminer versions 4.6.1 to 4.8.0 affects users of MySQL, MariaDB, PgSQL and SQLite. XSS is in most cases prevented by strict CSP in all modern browsers. The only exception is when Adminer is using a `pdo_` extension to communicate with the database (it is used if the native extensions are not enabled). In browsers without CSP, Adminer versions 4.6.1 to 4.8.0 are affected. The vulnerability is patched in version 4.8.1. As workarounds, one can use a browser supporting strict CSP or enable the native PHP extensions (e.g. `mysqli`) or disable displaying PHP errors (`display_errors`).

There are packages installed that are affected by a vulnerability referenced in the following CVE:

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.

The version of Adminer installed on the remote host does not sanitize user input used for the pdo_ extensions leading to a Cross-Site Scripting (XSS) vulnerability.

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