Executive brief
Pardus Pen, a Turkish security-focused operating environment, contains an argument injection vulnerability that could allow an attacker to inject malicious command arguments during execution. An unauthorized user could potentially manipulate command-line input to bypass intended security controls or execute unintended operations on an affected system.
Technical details
This vulnerability is classified as improper neutralization of argument delimiters in a command (CWE-88, argument injection). The root cause is insufficient validation and sanitization of user-supplied input when constructing or parsing command arguments in Pardus Pen. An attacker with local access or the ability to influence command arguments could inject malicious delimiters to alter the intended command structure. The attack requires an attacker to supply specially crafted arguments to a vulnerable code path. Versions before 4.2.1 are affected, and a patch is available in version 4.2.1 and later.
