⚠️ A sneaky path issue lets user inputs slip through without a proper check! iTerm2 before 3.5.0beta12 mishandles x-man-page URLs that could contain shell metacharacters. 🔥 Think of it like a restaurant that takes orders without asking whether customers want their food spicy or mild—the kitchen will just whip up whatever is requested, sometimes leading to a fiery surprise! An attacker could craft a malicious x-man-page URL that exploits this vulnerability, potentially executing unwanted commands on the system. While there’s no known exploit yet, the risk is still chilling, as it could lead to unauthorized access or actions if misused.
Think of it like a restaurant that takes orders without asking whether customers want their food spicy or mild—the kitchen will just whip up whatever is requested, sometimes leading to a fiery surprise! This vulnerability in iTerm2 arises from the lack of path sanitization in x-man-page URLs, allowing shell metacharacters to be passed unfiltered to the `/usr/bin/man` command line, which could result in unexpected command execution.
An attacker could craft a malicious x-man-page URL that exploits this vulnerability, potentially executing unwanted commands on the system.
