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


Severity Medium
Score 4.3/10


Variable overwrite vulnerability in interface/globals.php in OpenEMR 2.8.2 and earlier allows remote attackers to overwrite arbitrary program variables and conduct other unauthorized activities, such as conduct (a) remote file inclusion attacks via the srcdir parameter in custom/import_xml.php or (b) cross-site scripting (XSS) attacks via the rootdir parameter in interface/login/login_frame.php, via vectors associated with extract operations on the (1) POST and (2) GET superglobal arrays. NOTE: this issue was originally disputed before the extract behavior was identified in post-disclosure analysis. Also, the original report identified "Open Conference Systems," but this was an error.

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.
