CVE-2021-36385Network attack vector

Remote command execution via fullwidth-apostrophe SQL injection

Published Aug 24, 2021 · Updated Aug 4, 2024

SQL injection in Cerner Mobile Care 5.0.0 allows remote attackers to execute arbitrary SQL and system commands through the login form. The default.aspx User ID field fails to neutralize a fullwidth apostrophe (U+FF07) before incorporating the value into a backend SQL statement. No authentication or user interaction is required; an injected query can invoke xp_cmdshell for operating-system command execution.
