phpMyAdmin Improper Input Validation

Moderate severity GitHub Reviewed Published May 17, 2022 to the GitHub Advisory Database • Updated Apr 24, 2024

Package

composer phpmyadmin/phpmyadmin (Composer)

Affected versions

>= 4.5, < 4.5.5.1

Patched versions

4.5.5.1

Description

The checkHTTP function in libraries/Config.class.php in phpMyAdmin 4.5.x before 4.5.5.1 does not verify X.509 certificates from api.github.com SSL servers, which allows man-in-the-middle attackers to spoof these servers and obtain sensitive information via a crafted certificate.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
