• → Flag cmd_73730 messages where max_cnt is a large value such as 0x04924925, which triggers the integer overflow resulting in a small heap allocation (18 bytes) and subsequent heap buffer overflow. ↗
• → Detect unauthenticated registration abuse: monitor for CMD_REGISTER (command 2) messages to TCP port 5005 with console type 1 using the static credential string embedded in the packet. ↗

• · Exploitation of CVE-2022-25330 (integer overflow via command 73730) requires the attacker to first authenticate or exploit CVE-2022-25329 (static credential) to register as a client console on TCP port 5005. ↗
• · The attacker must supply a reachable Windows host and valid credentials in the cmd_73730 payload; the overflow is triggered when the server queries the attacker-controlled registry and copies a large number of Normal Server names into the undersized heap buffer. ↗
• · Affected version is Trend Micro ServerProtect for Microsoft Windows/Novell NetWare 5.8 build 1575; the vulnerable binary is EarthAgent.exe version 5.80.0.1575. ↗
