Linknat VOS3000 and VOS2009 through version 2.1.2.0 contain an unauthenticated SQL injection vulnerability that allows remote attackers to execute arbitrary SQL commands by manipulating the name parameter in a POST request to the login endpoint. Attackers can inject malicious SQL through the login form and retrieve injected query results from a subsequent session request, enabling extraction of plaintext credentials and other database content with DBA-level privileges.
