Detailsinfo

A vulnerability was found in Kunshi Network VOS2009 and VOS3000 up to 2.1.1.5/2.1.1.8/2.1.2.0. It has been classified as critical. This affects an unknown code of the component login endpoint. The manipulation of the argument name with an unknown input leads to a sql injection vulnerability. CWE is classifying the issue as CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.
