Improper Control of Generation of Code ('Code Injection')


Severity Medium
Score 6.8/10


Certain getText methods in the ActionSupport controller in Apache Roller before 5.0.2 allow remote attackers to execute arbitrary OGNL expressions via the first or second parameter, as demonstrated by the pageTitle parameter in the !getPageTitle sub-URL to roller-ui/login.rol, which uses a subclass of UIAction, aka "OGNL Injection."

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.
