In short

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.

Technical detail

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.

Summary generated and translated by AI from the official description.
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.
