request_monitor.sh" does not validate IP address input and fails on malformed input Affected File "scripts/request_monitor.sh"

Description

The script accepts the target IP directly from "$1" and passes it to "convert_ip_to_integers()" without validating that it is a valid IPv4 address.

The function then performs arithmetic operations on the parsed values. Malformed input can therefore cause arithmetic parsing errors and prevent the monitoring script from starting.

Reproduction

Run:

./scripts/request_monitor.sh 'invalid'

or provide an incomplete/malformed IPv4 address.

The script produces arithmetic parsing errors instead of displaying a clear validation error and exiting safely.

Impact

A malformed target supplied by a user or automation can cause the monitoring workflow to fail unexpectedly. This is primarily a robustness/input-validation issue rather than a confirmed privilege-escalation vulnerability.

Suggested Fix

Validate the argument before performing arithmetic conversion. For example, require a valid IPv4 address and reject invalid input with a clear error message.

Severity

Low — Input Validation / Reliability

Start with scripts/request_monitor.sh, especially the argument handling and convert_ip_to_integers(). Reproduce the issue with ./scripts/request_monitor.sh 'invalid' and an incomplete IPv4 address. Done means malformed input is rejected with a clear validation error before arithmetic parsing, while valid IPv4 input still starts monitoring.
