A vulnerability in the conferencing component of Mitel MiVoice Connect through 19.3 SP2 and 20.x, 21.x, and 22.x through 22.24.1500.0 could allow an unauthenticated attacker to conduct a reflected cross-site scripting (XSS) attack due to insufficient validation for the home.php page. A successful exploit could allow an attacker to execute arbitrary scripts.

A vulnerability in the web conferencing component of Mitel MiCollab through 9.6.2.9 could allow an unauthenticated attacker to download a shared file via a crafted request - including the exact path and filename - due to improper authentication control. A successful exploit could allow access to sensitive information.

The ccmweb component of Mitel MiContact Center Business server 9.2.2.0 through 9.4.1.0 could allow an unauthenticated attacker to download arbitrary files, due to insufficient restriction of URL parameters. A successful exploit could allow access to sensitive information.

The web conferencing component of Mitel MiCollab through 9.6.0.13 could allow an unauthenticated attacker to upload arbitrary scripts due to improper authorization controls. A successful exploit could allow remote code execution within the context of the application.

A vulnerability in the web conferencing component of Mitel MiCollab through 9.5.0.101 could allow an unauthenticated attacker to upload malicious files. A successful exploit could allow an attacker to execute arbitrary code within the context of the application.

A vulnerability in the MiCollab Client server component of Mitel MiCollab through 9.5.0.101 could allow an authenticated attacker to conduct a Server-Side Request Forgery (SSRF) attack due to insufficient restriction of URL parameters. A successful exploit could allow an attacker to leverage connections and permissions available to the host server.

A vulnerability in the MiCollab Client API of Mitel MiCollab 9.1.3 through 9.5.0.101 could allow an authenticated attacker to modify their profile parameters due to improper authorization controls. A successful exploit could allow the authenticated attacker to control another extension number.

A vulnerability in the MiCollab Client API of Mitel MiCollab through 9.5.0.101 could allow an authenticated attacker to modify their profile parameters due to improper authorization controls. A successful exploit could allow the authenticated attacker to impersonate another user's name.

A vulnerability in the management interface of MiVoice Business through 9.3 PR1 and MiVoice Business Express through 8.0 SP3 PR3 could allow an unauthenticated attacker (that has network access to the management interface) to conduct a buffer overflow attack due to insufficient validation of URL parameters. A successful exploit could allow arbitrary code execution.

A vulnerability in Mitel 6900 Series IP (MiNet) phones excluding 6970, versions 1.8 (1.8.0.12) and earlier, could allow a unauthenticated attacker with physical access to the phone to gain root access due to insufficient access control for test functionality during system startup. A successful exploit could allow access to sensitive information and code execution.
