CVE-2020-11441Public exploitNetwork attack vector

Error-page input reflection via unescaped CRLF sequences

Published Mar 31, 2020 · Updated Aug 4, 2024

CRLF injection in phpMyAdmin 5.0.2 allows remote attackers to reflect encoded line breaks through login form fields on an error page. The login error path echoes submitted username, password, or hidden target values without removing URL-encoded CRLF sequences. Reaching the reflection requires crafted login input, and phpMyAdmin disputes that the behavior has any specifically exploitable consequence.
