Command Injection in Mitel 6800/6900/6900w Series SIP Phones

IdentifiersCVE-2024-41710CWE-78

CVE-2024-41710 is a command/argument injection vulnerability affecting Mitel 6800 Series, 6900 Series, and 6900w Series SIP Phones, including the 6970 Conference Unit, through firmware R6.4.0.HF1 (R6.4.0.136). The issue is caused by insufficient parameter sanitization during the boot process, allowing an authenticated attacker with administrative privileges to inject crafted arguments that are interpreted by the underlying system. Public reporting and observed exploitation indicate the flaw can be abused via device configuration handling, including the 8021xsupport.html endpoint, to introduce malicious content that is later processed during boot. Successful exploitation results in arbitrary command execution in the system context; supporting reporting indicates this can lead to root-level access on affected devices.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows arbitrary command execution on the affected SIP phone. Based on the supporting reporting, exploitation can yield root access on the device, enabling full compromise of the phone, execution of malware, modification of configuration, persistence, and use of the device as a botnet node. In observed in-the-wild activity, attackers used the flaw to fetch and execute shell scripts that installed Mirai-derived malware for DDoS operations.

Mitigation

If you can’t patch tonight, do this now.

Restrict administrative access to trusted management networks only, disable or tightly control remote administration, and limit exposure of phone management interfaces and provisioning paths from untrusted networks. Enforce strong unique administrator credentials, monitor for unexpected access to configuration-related endpoints such as 8021xsupport.html, and inspect outbound connections for suspicious payload retrieval or C2 traffic. Where immediate patching is not possible, isolate vulnerable phones with network segmentation and egress filtering to reduce the likelihood of exploitation and post-compromise malware download.

Remediation

Patch, then assume compromise.

Upgrade affected Mitel 6800 Series, 6900 Series, and 6900w Series SIP Phones, including the 6970 Conference Unit, to a fixed firmware release newer than R6.4.0.HF1 (R6.4.0.136), in accordance with Mitel vendor guidance. Review device configurations for unauthorized changes, inspect for indicators of compromise, and reimage or factory-reset and reprovision devices if compromise is suspected, since successful exploitation may provide root-level execution and persistence.
