Unauthenticated SQL Injection Leading to Remote Code Execution in Switchvox SMB
Affects Sangoma Switchvox SMB from 8.3 (104997) before 8.4.0.2, through the /pa endpoint's handling of Polycom phone XML. Fixed in 8.4.0.2.

Summary
Sangoma Switchvox SMB Edition, a business phone system platform, is affected by a flaw that lets an unauthenticated remote attacker inject SQL commands through a crafted request and run them against its backend PostgreSQL database. This can allow attackers to manipulate or access database data and potentially execute code remotely on the affected system.
Summarized by anthropic/claude-haiku-5.5. Verify details against the original sources.
Read the original 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.

Questions about CVE-2026-9586
What does this mean?
The /pa endpoint takes the user-controlled PhoneIP value from XML content beginning with <PolycomIPPhone> and concatenates it directly into PostgreSQL queries without sanitization or parameterization. This allows arbitrary SQL statements to run against the backend database, including database operations and remote code execution.Source: labs.sra.io
Am I affected, and how do I check?
Sangoma Switchvox SMB from 8.3 (104997) before 8.4.0.2 is affected. The issue involves the /pa endpoint processing XML that begins with <PolycomIPPhone>, so the installed version is the first thing to check against this range.Source: labs.sra.io
What should I do about it?
Update Sangoma Switchvox SMB to 8.4.0.2 or later. The sources do not list a workaround.Source: labs.sra.io
Is it being exploited?
Yes. CISA added it to its Known Exploited Vulnerabilities catalog on 2026-09-02, which means it has evidence of attacks. No public exploit code is tracked.Source: cisa.gov, cve.now feed data
