Unauthenticated SQL Injection Leading to Remote Code Execution in Switchvox SMB

CVSS 4.0 Critical 9.3Known exploited (CISA KEV)

CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N

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.
