As part of Mitel’s ongoing commitment to customers and product excellence, Mitel maintains a dedicated product security incident response program to handle the discovery of potential vulnerabilities and security flaws in products.
Public notices regarding moderate and high-risk product security vulnerabilities are published at Security Advisories.
Mitel uses the industry-recognized Common Vulnerability Scoring System (CVSS) as part of its process to evaluate the risk introduced by potential vulnerabilities in Mitel products.
The use of CVSS version 2.0* is intended as a general guideline; it is recommended that Mitel customers should evaluate the risk themselves, with consideration given to their specific use of the product and environment.
Response to vulnerabilities is prioritized based on the level of risk associated with the security vulnerability when exposure is confirmed in Mitel products. The following table identifies Mitel internal response guidelines as mapped to CVSS 2.0 scoring:
|CVSS v2 Score Range|
|High||8.0 to 10.0|
|Medium||6.0 to 7.9|
*The use of CVSS version 3.0 scoring is being evaluated and will be introduced at a later date.
The Mitel Product Security Incident Response Team (PSIRT) will investigate and disclose vulnerabilities for actively supported products. Once a security vulnerability has been confirmed, Mitel will provide solutions commensurate of the risk identified.
Low Risk Vulnerabilities will be corrected as part of the standard product release cycle. For additional information, contact Support.
Mitel’s first and foremost concern is our customers. To this end, Mitel will not publicly publish any details that could potentially be used to comprise products until mitigation is available to reduce or eliminate risk. Critical information will be circulated directly to channel partners and distributors or customers in a timely manner as required, commensurate of the risk.
Mitel respects the security considerations of all customers and will not provide advanced details outside of established channels.
Product security vulnerabilities are communicated via a monthly cadence published to Security Advisories. Monthly updates are posted within four business days following the end of the reporting period.
Advisories and bulletins will be published outside of the monthly schedule for high-risk and high-profile security vulnerabilities.
The Mitel Product Security Incident Response Team provides direct support for potential vulnerabilities identified in Mitel products. Mitel will work with customers and recognized security organizations to resolve detected security vulnerabilities.
