CVE-1999-0755

28
FAUCET Score

CVE-1999-0755 describes a vulnerability in Microsoft Windows NT and 2000 where the Remote Access Service (RAS) and Routing and Remote Access Service (RRAS) clients cache user passwords even when the "Save password" option is not selected. This medium-severity vulnerability (CVSS 5.0) allows an unauthenticated attacker with network access to potentially gain unauthorized access to cached credentials, leading to a compromise of confidentiality. While there is no evidence of active exploitation or Metasploit/Nuclei modules, an ExploitDB entry exists, and the vulnerability has a high FAUCET Risk Score despite minimal community discussion or media coverage.
