CVE-2020-5504: In phpMyAdmin 4 before 4.9.4 and 5 before 5.0.1, SQL injection exists in the user accounts page.

In phpMyAdmin 4 before 4.9.4 and 5 before 5.0.1, SQL injection exists in the user accounts page. A malicious user could inject custom SQL in place of their own username when creating queries to this page. An attacker must have a valid MySQL account to access the server.

Security readout for executives and security teams

CVE-2020-5504 is an authenticated SQL injection in phpMyAdmin's user accounts page. A user with a valid MySQL account could manipulate SQL generated by that page using their own username. This is most urgent where phpMyAdmin is exposed to many users or reachable beyond trusted administration networks. Exposure is likely limited to environments running vulnerable phpMyAdmin versions with reachable login access and valid MySQL users. Internet-facing phpMyAdmin, shared hosting, lab systems, and broadly accessible admin portals carry higher concern. Prioritize remediation for internet-facing or multi-user phpMyAdmin systems. The authentication requirement reduces urgency compared with unauthenticated SQL injection, but database administration tooling is high-value and should not remain on known vulnerable versions. Mitigation focus: Upgrade phpMyAdmin 4.x to 4.9.4 or later.; Upgrade phpMyAdmin 5.x to 5.0.1 or later.; Apply Debian or openSUSE security packages where those distributions manage phpMyAdmin..
