CVE-2024-41710
CVE-2024-41710 is a security flaw in Mitel SIP Phones. Someone who already has a way in can use Mitel SIP Phones to run their own code. The US Cybersecurity and Infrastructure Security Agency (CISA) added it to its catalog of flaws known to be used in attacks on 12 Feb 2025.[1]
Mitel SIP Phones is business software or equipment. Most families won’t have it, but attackers break into it to get inside companies, and from there to what those companies hold about their customers, patients and staff. Mitel has published a fix or advice.
Description
CISA calls it an argument injection in Mitel SIP Phones. In its words: “Mitel 6800 Series, 6900 Series, and 6900w Series SIP Phones, including the 6970 Conference Unit, contain an argument injection vulnerability due to insufficient parameter sanitization during the boot process. Successful exploitation may allow an attacker to execute arbitrary commands within the context of the system.”[1]
The CVE record adds: “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.”[2]
The underlying weakness is CWE-88, in MITRE’s list of common software weaknesses.
It scores 7.2 out of 10 on the Common Vulnerability Scoring System, which rates it high, scored by NVD using CVSS 3.1.[2]
Affected versions
NVD’s record doesn’t list version ranges for it; Mitel’s advisory has them[3]. CISA names the product as Mitel SIP Phones.
Most families won’t have Mitel SIP Phones; it’s for whoever looks after IT at work.
Exploitation
CISA added it to its catalog of known exploited vulnerabilities on 12 Feb 2025, 184 days after it was made public. CISA lists a flaw only when it has reliable evidence of it being exploited, and gave US federal agencies until 5 Mar 2025 to fix it.[1]
FIRST’s Exploit Prediction Scoring System, which estimates how likely a flaw is to be used in attacks in the next 30 days from what it sees across the internet, puts it at 42%. That’s in the top 2% of the flaws it scores.[4]
CISA assesses it as not automatable: each attack takes some work.
CISA doesn’t say who was attacked, or how.
Fix
Mitel has published a fix or advice.[3] CISA’s required action: “Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.”[1]
- Check whether you use it.Mitel SIP Phones is business software or equipment, so most families won’t have it. If you run a business, or work from home on company equipment, ask whoever looks after your IT.
- Send this page to your IT person.Ask them to confirm it’s fixed, or not in use. CISA gave US government agencies until 5 Mar 2025 to fix it.
- If it can’t be fixed, take it offline.CISA’s advice when there’s no fix is to stop using the product, or take it off the internet, until there is one.
You can’t fix someone else’s server, but you can watch for what follows a break-in like this: a breach notice, a password reset you didn’t ask for, or a scam message that knows things it shouldn’t. HARD watches for those for you and your family.
