Adminer

Adminer is open-source database management software. Adminer v5.4.1 and earlier has a version check mechanism where adminer.org sends signed version info via JavaScript postMessage, which the browser then POSTs to ?script=version. This endpoint lacks origin validation and accepts POST data from any source. An attacker can POST version[] parameter which PHP converts to an array. On next page load, openssl_verify() receives this array instead of string and throws TypeError, returning HTTP 500 to all users. Upgrade to Adminer 5.4.2.

The file upload plugin in Adminer and AdminerEvo allows an attacker to upload a file with a table name of “..” to the root of the Adminer directory. The attacker can effectively guess the name of the uploaded file and execute it. Adminer is no longer supported, but this issue was fixed in AdminerEvo version 4.8.3.

Adminer and AdminerEvo allow an unauthenticated remote attacker to cause a denial of service by connecting to an attacker-controlled service that responds with HTTP redirects. The denial of service is subject to PHP configuration limits. Adminer is no longer supported, but this issue was fixed in AdminerEvo version 4.8.4.

Adminer and AdminerEvo are vulnerable to SSRF via database connection fields. This could allow an unauthenticated remote attacker to enumerate or access systems the attacker would not otherwise have access to. Adminer is no longer supported, but this issue was fixed in AdminerEvo version 4.8.4.

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`).
