How to Fix CVE-2019-6799

To remediate this vulnerability, upgrade all affected Phpmyadmin/phpmyadmin dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

phpmyadmin/phpmyadmin fixed: 4.8.5 
Upgrade phpmyadmin/phpmyadmin to 4.8.5
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

How to Check if You Are Affected

To determine whether your application is affected by CVE-2019-6799, inspect your project dependencies for Phpmyadmin/phpmyadmin:

inspect dependencies for phpmyadmin/phpmyadmin

Analyze the terminal output to locate any version of Phpmyadmin/phpmyadmin in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.8.5), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Phpmyadmin/phpmyadmin, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

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.
