Recommendation: Plan a near-term fix — a public PoC already exists.
Terminal Services Manager 3.1 contains a stack-based buffer overflow vulnerability in the computer names field that allows local attackers to execute arbitrary code by triggering structured exception handling. Attackers can craft a malicious input file with shellcode and jump instructions that overwrite the SEH handler pointer to execute calc.exe or other payloads when imported through the add computers wizard.
