port 7510↗

command /bin/echo 1 1 | nc -vv <target>:7510↗

command 1 1 ↗

• → Alert on any inbound TCP connection to port 7510 on POS terminals running Xpient Iris 3.8; the exploit requires no authentication and sends a two-integer payload ('1 1') to trigger the cash drawer. ↗
• → Monitor for repeated TCP connections (up to 4 in quick succession with 1-second sleep intervals) to port 7510 from a single source, matching the PoC loop behavior. ↗
• → Apply host-based firewall rules (e.g. Windows Firewall) on POS terminals to block all inbound traffic to TCP port 7510 as a compensating control. ↗

• · Only Iris 3.8 builds prior to 1548 are vulnerable; build 1548 and higher are patched. Confirm the exact build number on target POS terminals before triaging alerts. ↗
• · The vulnerability requires network-level access to the POS terminal; exploitation is only possible if an attacker (or malware) can reach the POS network segment. ↗
