Command Injection via shell=True
High
Location: test_cases/cmd_injection_logic.py (Line 15) Forensic Evidence
subprocess.run(f"ls {user_input}", shell=True)
Description & Analysis

Using shell=True with subprocess allows attackers to execute arbitrary shell commands through user input.

Attack Vector: An attacker can input malicious commands, leading to unintended command execution on the host system.

🛡 Recommended Remediation

Use a list of arguments without shell=True, like subprocess.run(['ls', user_input]).

Command Injection via shell=True
High
Location: test_cases/cmd_injection_logic.py (Line 16) Forensic Evidence
subprocess.check_call("echo " + user_input, shell=True)
Description & Analysis

Using shell=True with subprocess can allow attackers to execute arbitrary commands through the injection of user input.

Attack Vector: An attacker could include shell metacharacters in user_input, resulting in unexpected command execution.

🛡 Recommended Remediation

Avoid shell=True and pass a list of arguments instead, like subprocess.check_call(['echo', user_input]).

Command Injection via os.system
High
Location: test_cases/cmd_injection_logic.py (Line 20) Forensic Evidence
os.system(f"rm -rf {user_input}")
Description & Analysis

Using os.system with user input can lead to arbitrary command execution, causing critical security risks.

Attack Vector: An attacker could provide input that leads to the deletion of critical files or unauthorized data access.

🛡 Recommended Remediation

Use safer alternatives like subprocess.run with a list of arguments, and avoid os.system.

Command Injection via os.popen
High
Location: test_cases/cmd_injection_logic.py (Line 21) Forensic Evidence
os.popen(f"cat {user_input}")
Description & Analysis

Using os.popen with unsanitized user input exposes the application to command injection vulnerabilities.

Attack Vector: An attacker can input malicious data leading to arbitrary command execution on the system.

🛡 Recommended Remediation

Use safer command-execution techniques, ensuring user input is properly sanitized or validated.

Unsafe eval usage
High
Location: test_cases/cmd_injection_logic.py (Line 25) Forensic Evidence
eval(user_input)
Description & Analysis

Using eval with user input can execute arbitrary code, making it one of the most dangerous code execution risks.

Attack Vector: An attacker can input malicious Python code, leading to remote code execution and potentially full system compromise.

🛡 Recommended Remediation

Avoid using eval and exec with user-controlled inputs entirely. Consider alternative approaches to achieve your goal.

Unsafe Eval/Exec Usage
High
Location: test_cases/cmd_injection_logic.py (Line 26) Forensic Evidence
exec("print(" + user_input + ")")
Description & Analysis

The use of eval() and exec() with user input is highly dangerous and can lead to arbitrary code execution. Any malicious code provided by the user will be executed.

Attack Vector: An attacker could input malicious code as 'os.system('ls')' to execute arbitrary system commands or any other harmful operations.

🛡 Recommended Remediation

Avoid using eval() and exec() with untrusted input. Consider using safer alternatives or validating and sanitizing input before executing.
