Improper Control of Generation of Code ('Code Injection')
PHP remote file include vulnerability in index.php for Gallery 1.4 and 1.4-pl1, when running on Windows or in Configuration mode on Unix, allows remote attackers to inject arbitrary PHP code via a URL in the GALLERY_BASEDIR parameter, a different vulnerability than CVE-2002-1412. NOTE: this issue might be exploitable only during installation, or if the administrator has not run a security script after installation.
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.
