CyberRota Analysis

AI-Generated

Adminer versions prior to 5.4.3 are vulnerable due to the insertion of unsanitized database server version strings into script tags, which can lead to arbitrary code execution when attackers manipulate a rogue MySQL server. This vulnerability allows attackers to bypass Content Security Policy protections, posing a risk to applications relying on Adminer for database management. Organizations using affected versions of Adminer should prioritize patching to mitigate potential exploitation.

Original NVD Description

Adminer before 5.4.3 inserts unsanitized database server version strings into script tags with valid CSP nonces without proper validation. Attackers controlling a rogue MySQL server can return crafted version strings that break out of the JavaScript context and execute arbitrary code, bypassing Content Security Policy protections.
