Description

An issue was discovered in phpMyAdmin before 4.8.5. When the AllowArbitraryServer configuration setting is set to true, with the use of a rogue MySQL server, an attacker can read any file on the server that the web server's user can access. This is related to the mysql.allow_local_infile PHP configuration, and the inadvertent ignoring of "options(MYSQLI_OPT_LOCAL_INFILE" calls.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for phpmyadmin/phpmyadmin, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update phpmyadmin/phpmyadmin to 4.8.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2019-6799 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
