Technical description

phpMyAdmin 4.0.x before 4.0.10.16, 4.4.x before 4.4.15.7, and 4.6.x before 4.6.3 does not properly choose delimiters to prevent use of the preg_replace e (aka eval) modifier, which might allow remote attackers to execute arbitrary PHP code via a crafted string, as demonstrated by the table search-and-replace implementation.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
