- Fix
4.0.10.13- Upgrade phpmyadmin/phpmyadmin to this version or later
Description
libraries/common.inc.php in phpMyAdmin 4.0.x before 4.0.10.13, 4.4.x before 4.4.15.3, and 4.5.x before 4.5.4 does not use a constant-time algorithm for comparing CSRF tokens, which makes it easier for remote attackers to bypass intended access restrictions by measuring time differences.
Affected versions
Packagist
| Package | Vulnerable | Fixed in |
|---|---|---|
| phpmyadmin/phpmyadmin | >= 4.0, < 4.0.10.13 |
4.0.10.13 |
| phpmyadmin/phpmyadmin | >= 4.4, < 4.4.15.3 |
4.4.15.3 |
| phpmyadmin/phpmyadmin | >= 4.5, < 4.5.4 |
4.5.4 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

Weakness
CWE-203: Observable Discrepancy
The product behaves differently or sends different responses under different circumstances in a way that is observable to an unauthorized actor.
How to prevent it
- Architecture and Design: Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
- Implementation: Ensure that error messages only contain minimal details that are useful to the intended audience and no one else. The messages need to strike the balance between being too cryptic (which can confuse users) or being too detailed (which may reveal more than intended). The messages should not reveal the methods that were used to determine the error. Attackers can use detailed information to refine or optimize their original attack, thereby increasing their chances of success. If errors must be captured in some detail, record them in log messages, but consider what could occur if the log messages can be viewed by attackers. Highly sensitive information such as passwords should never be saved to log files. Avoid inconsistent messaging that might accidentally tip off an attacker about internal state, such as whether a user account exists or not.
