Improper Control of Generation of Code ('Code Injection')
Multiple eval injection vulnerabilities in Php-Stats 0.1.9.2 allow remote authenticated administrators to execute arbitrary code by writing PHP sequences to the php-stats-options record in the _options table, which is used in an eval function call by (1) admin.php, (2) click.php, (3) download.php, and unspecified other files, as demonstrated by modifying _options through a backup restore action in admin.php.
CWE-94 - Code Injection
Code injection is a type of vulnerability that allows an attacker to execute arbitrary code. This vulnerability fully compromises the machine and can cause a wide variety of security issues, such as unauthorized access to sensitive information, manipulation of data, denial of service attacks etc. Code injection is different from command injection in the fact that it is limited by the functionality of the injected language (e.g. PHP), as opposed to command injection, which leverages existing code to execute commands, usually within the context of a shell.
