Affected: mitel 6940_sip_firmware, mitel 6905_sip_firmware, mitel 6910_sip_firmware, mitel 6915_sip_firmware, mitel 6920_sip_firmware, mitel 6920w_sip_firmware, mitel 6930w_sip_firmware, mitel 6940w_sip_firmware, mitel 6970_conference_firmware

A vulnerability in the Mitel 6800 Series, 6900 Series, and 6900w Series SIP Phones, including the 6970 Conference Unit, through R6.4.0.HF1 (R6.4.0.136) could allow an authenticated attacker with administrative privilege to conduct an argument injection attack, due to insufficient parameter sanitization during the boot process. A successful exploit could allow an attacker to execute arbitrary commands within the context of the system.
