CVE-2018-11746

27
FAUCET Score

CVE-2018-11746 is a critical vulnerability affecting Puppet Discovery prior to version 1.2.0, where WinRM connections to Windows hosts can insecurely fall back to basic authentication over unencrypted channels if HTTPS is unavailable. This allows for the exposure of login credentials used by Puppet Discovery. With a CVSS score of 9.8 (Critical), it presents a high-impact risk due to its network-based attack vector, low complexity, and potential for complete compromise of confidentiality, integrity, and availability. While no active exploitation, public exploit code, or significant community discussion has been observed, its high FAUCET Risk Score of 77/100 indicates a substantial inherent risk.
