Security Audit of Shell Script Execution

[BhoomiAgrawal12]

Description

SecureWipe executes several shell scripts and system commands. We need a comprehensive security audit to ensure there are no command injection vulnerabilities or unsafe practices.

Areas to Audit

1. Shell Script Execution

   • scripts/android-wipe.sh
   • scripts/detect-android.sh
   • scripts/attest.sh
   • scripts/verify_attest.sh

2. User Input Handling

   • Device path selection
   • Operator ID input
   • Any user-provided strings used in commands

3. Command Execution in C++ Code

   • Check all instances of system() calls
   • Review exec.cpp for safe execution
   • Ensure proper escaping of arguments

4. Privilege Escalation

   • How root privileges are requested
   • Minimize scope of privileged operations
   • Validate before executing privileged commands

Security Concerns

• Command injection through device paths
• Unsafe string concatenation in shell commands
• Insufficient input validation
• Race conditions in device access
• Temporary file handling

Proposed Actions

1. Replace system() calls with safer alternatives
2. Implement input sanitization and validation
3. Use parameterized command execution
4. Add bounds checking
5. Review and update all shell scripts

Acceptance Criteria

• Complete security audit report
• All identified vulnerabilities patched
• Security testing performed
• Code review by security-focused contributor
• Documentation of security measures
