How to Fix CVE-2018-12613

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: 4.8.2 
Upgrade phpmyadmin/phpmyadmin to 4.8.2
Verify Direct and Transitive Dependencies

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

inspect dependencies for phpmyadmin/phpmyadmin

How to Check if You Are Affected

To determine whether your application is affected by CVE-2018-12613, 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 4.8.2), 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-287: Improper Authentication, where when an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. 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 4.8.x before 4.8.2, in which an attacker can include (view and potentially execute) files on the server. The vulnerability comes from a portion of code where pages are redirected and loaded within phpMyAdmin, and an improper test for whitelisted pages. An attacker must be authenticated, except in the "$cfg['AllowArbitraryServer'] = true" case (where an attacker can specify any host he/she is already in control of, and execute arbitrary code on phpMyAdmin) and the "$cfg['ServerDefault'] = 0" case (which bypasses the login requirement and runs the vulnerable code without any authentication).
