🛡️ Sentinel: [MEDIUM] Fix CRLF Log Injection in Exception Handler#86ManupaKDU wants to merge 1 commit into
Conversation
🚨 Severity: MEDIUM 💡 Vulnerability: The script's `__main__` block exception handler directly embedded arbitrary user-supplied input (`start_ip` and `end_ip` parsing errors via `str(e)`) into `logging.error()`. An attacker supplying strings containing newline characters (CRLF) could forge or obfuscate log entries. 🎯 Impact: Log Injection (CRLF), allowing attackers to falsify log records, hide malicious activity, or disrupt log parsing systems. 🔧 Fix: Sanitized the exception message by wrapping the string representation in `repr()`, securely escaping control characters. ✅ Verification: Added an isolated unit test using `subprocess.run` to verify that newline payloads in `start_ip` exceptions are safely escaped in `stderr`.
