⚠️ Firejail has a sneaky way of mishandling shell metacharacters, turning your innocent commands into potential entry points for attackers! Think of it like a restaurant that doesn’t check your order carefully. If you just scribble some extra instructions on the ticket, the kitchen might whip up something dangerous, like a surprise ingredient that ruins your meal! This flaw could allow an attacker to inject malicious commands directly into the system, running arbitrary code and potentially wreaking havoc. We're talking unauthorized access to sensitive data or control over processes that should remain secure!
Think of it like a restaurant that doesn’t check your order carefully. If you just scribble some extra instructions on the ticket, the kitchen might whip up something dangerous, like a surprise ingredient that ruins your meal! In versions of Firejail up to 0.9.62, mishandling of shell metacharacters during the use of the `--output` or `--output-stderr` options can be exploited for command injection, leading to severe consequences for system security.
This flaw could allow an attacker to inject malicious commands directly into the system, running arbitrary code and potentially wreaking havoc.
