CVE-2016-20096 (GCVE-0-2016-20096)

Vulnerability from cvelistv5 – Published: 2026-07-21 18:59 – Updated: 2026-07-22 19:06

Title

Linknat VOS3000/VOS2009 2.1.2.0 SQL Injection via login.jsp

Summary

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.
