Background
phpMyAdmin is a popular open-source tool written in PHP that provides a web-based interface for managing MySQL databases. It allows users to perform various database administration tasks such as creating, modifying, and deleting databases, tables, and records. The vulnerability identified as CVE-2011-2506 affects phpMyAdmin versions 3.x before 3.3.10.2 and 3.4.x before 3.4.3.1.
Vulnerability Detail
The vulnerability in phpMyAdmin arises from the improper restriction of comment closing delimiters in the 'setup/lib/ConfigGenerator.class.php' file. This flaw enables remote attackers to conduct static code injection attacks by exploiting their ability to modify the SESSION superglobal array. By injecting malicious code, an attacker can execute arbitrary commands on the server, potentially leading to unauthorized access, data manipulation, or even complete system compromise.

Specifically, the code responsible for handling the SESSION superglobal array should be reviewed and modified to ensure proper input validation and sanitization. However, applying this workaround is not recommended as it may introduce errors or unintended consequences. It is strongly advised to prioritize upgrading to the latest version instead.
Conclusion
The static code injection vulnerability in phpMyAdmin can have severe consequences if left unaddressed.
