CVE-2021-43935 is a critical improper authentication vulnerability affecting several Baxter Welch Allyn medical devices when configured for Single Sign-On (SSO). An attacker can gain unauthorized access to these applications by manually entering any provisioned Active Directory account username without a password, thereby assuming all associated privileges. This vulnerability carries a CVSS score of 9.8 (Critical) due to its network-based attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability. Despite its severity, there is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
