Summary

Leakage of line count of an arbitrary file.

Description

In the error reporting feature, a parameter specifying the file was not correctly validated, allowing the attacker to derive the line count of an arbitrary file.

Severity

Mitigation factor

This vulnerability can be triggered only by someone who is logged in to phpMyAdmin, as the usual token protection prevents non-logged-in users from accessing the required page.
