Vulnerability Title

Unauthenticated SQL Injection Leading to Remote Code Execution in Switchvox SMB

Source: CVE Program / CVE List V5

Vulnerability 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.

II. Public POCs for CVE-2026-9586

#	POC Description	Source Link	Shenlong Link
1	Sangoma Switchvox before version 8.4.0.2 contains an unauthenticated SQL injection vulnerability in the /pa endpoint (PhoneAppsHandler.pm). The PhoneIP field extracted from an XML POST body is concatenated directly into an unparameterized PostgreSQL query that runs as a database superuser. An attacker can break out of the single-quoted SQL string context and leverage PostgreSQL COPY TO PROGRAM to execute arbitrary operating system commands without authentication.	https://github.com/projectdiscovery/nuclei-templates/blob/main/http/cves/2026/CVE-2026-9586.yaml	POC Details
