A flaw in Sangoma Switchvox SMB allows anyone on the internet to inject malicious SQL commands through a public endpoint, potentially letting attackers steal data or take control of the system without needing a password.
An unauthenticated SQL injection vulnerability in the /pa endpoint of Switchvox SMB 8.3 (104997) occurs when user-controlled PhoneIP values from XML requests are directly concatenated into PostgreSQL queries without parameterization. Remote attackers can execute arbitrary SQL statements and achieve remote code execution on the backend database server via a single crafted request.
