An exploitable SQL injection vulnerability exists in the administrator web portal function of coTURN prior to version 4.5.0.9. A login message with a specially crafted username can cause an SQL injection, resulting in authentication bypass, which could give access to the TURN server administrator web portal. An attacker can log in via the external interface of the TURN server to trigger this vulnerability.
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.
