SQL injection vulnerability in the authentication module in Convivance StandVoice 4.5 through 6.2 allows remote attackers to execute arbitrary code via the GEST_LOGIN parameter.
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. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
