Horizon Alert
Summary of the vulnerability and why it matters
A vulnerability exists in Mitel SIP phones, including the 6800, 6900, and 6900w series. This flaw allows an authenticated attacker with administrative access to inject arguments into the system during its boot process. Successful exploitation could enable an attacker to execute arbitrary commands on the affected system.
- Mitel SIP phones
- Insufficient parameter sanitization
- Arbitrary command execution
Attack Path
How an attacker could exploit the issue
This vulnerability allows an authenticated attacker with administrative access to execute arbitrary commands on affected Mitel SIP phones. The attack exploits insufficient sanitization of parameters during the device's boot process. Successful exploitation can lead to a compromise of the system's context, enabling the attacker to run unauthorized commands.
- Exposure condition: Administrative access required.
- Attacker starting point: Network access.
- Trigger and result: Argument injection, command execution.The vulnerability in Mitel SIP phones allows an authenticated attacker with administrative privileges to execute arbitrary commands. This occurs due to insufficient sanitization of parameters during the boot process. A successful exploit could grant the attacker control within the system's context, potentially impacting confidentiality, integrity, and availability.
- Requires administrative access.
- Attacker exploits boot process.
- Leads to command execution.
