LoginUnauthenticated SQL Injection Leading to Remote Code Execution in Switchvox SMB
An unauthenticated SQL injection vulnerability exists in Sangoma Switchvox SMB Edition 8.3 (104997). The /pa endpoint processes XML content beginning with <PolycomIPPhone> and directly concatenates the user-controlled PhoneIP value into PostgreSQL queries without sanitization or parameterization. An unauthenticated remote attacker can execute arbitrary SQL statements against the backend PostgreSQL database using a single crafted request, including database operations and remote code execution.

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.
