CVE-1999-0249 · Severity: high · CVSS 7.2 · Published 1997-01-01

A vulnerability in the Windows NT Remote Shell service (RSHSVC) allows users to execute unauthorized commands on the system. This could lead to a complete compromise of the server, including the theft of sensitive data or the disruption of critical operations. Organizations still running legacy Windows NT systems are at risk of local attackers gaining full administrative control.
