HDX - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Vulnerability Summary

The Poly HDX is susceptible to a SQL injection vulnerability via a maliciously crafted call setup message that could lead to remote code execution. Poly made changes to the HDX software starting with the commercial software build to prevent this vulnerability. Input validation was improved so that these special characters are no longer allowed in systems names and are also no longer processed as instructions.

Poly recommends customers upgrade to firmware build or later.



For customers who cannot upgrade to a fixed version, Poly recommends that customers evaluate network access control lists, firewalls, and other network protection to ensure that they have been deployed in a manner that is consistent with security best practices. The risk presented by this potential vulnerability to Poly products, as well as other networked devices, may be mitigated by these controls. Customers should also ensure that Poly products have been configured as recommended by Poly implementation guides.


Any customer using an affected system who is concerned about this vulnerability within their deployment should contact Poly Technical Support(888) 248-4143, (916) 928-7561, or visit the Poly Support Site.



Poly would like to thank Moritz Jodeit & Mr. Jodeit of n.runs for reporting security vulnerabilities to us and for their coordinated disclosure.
