Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: A stack-based buffer overflow in the Core Server HMI Service.β¦
π‘οΈ **Root Cause**: Improper boundary checking. The `Coreservice.exe` component fails to validate the length of input strings received via TCP port 23.β¦
π **Affected**: Scadatec Limited Procyon SCADA Core Server. π¦ **Versions**: Specifically **Procyon SCADA 1.06** and earlier versions (up to but not including 1.14). The vulnerable component is `Coreservice.exe`.
Q4What can hackers do? (Privileges/Data)
π **Attacker Impact**: Remote Code Execution (RCE). By exploiting the overflow, hackers can gain control over the underlying operating system.β¦
β οΈ **Exploitation Threshold**: **LOW**. The vulnerability is triggered via TCP port 23 (Telnet). It requires sending a specific malformed string.β¦
π’ **Public Exploit**: The data lists third-party advisories (Secunia, X-Force, OSVDB, SecurityFocus) but **no direct PoC code** is provided in the `pocs` array.β¦
π **Self-Check**: Scan for **TCP Port 23** open on servers running Scadatec Procyon. Check if the service is `Coreservice.exe`. Look for version numbers **1.06 or lower**.β¦
π§ **No Patch Workaround**: If you cannot upgrade immediately: 1. **Block TCP Port 23** at the firewall/network level. 2. Restrict access to the SCADA network segment. 3.β¦
