Citrix SD-WAN and NetScaler SD-WAN - SQL Injection

Citrix SD-WAN 10.2.x before 10.2.3 and NetScaler SD-WAN 10.0.x before 10.0.8 contain an SQL injection vulnerability. An unauthenticated attacker can exploit improper validation of input in specific components, which could allow for execution of arbitrary SQL queries against the backend database. This could result in information disclosure, manipulation of data, or complete compromise of affected systems.
