CVE-2024-47575
CVE-2024-47575 is a security flaw in Fortinet FortiManager, Fortinet’s business security equipment. Attackers can run their own code on Fortinet FortiManager from anywhere, without logging in. The US Cybersecurity and Infrastructure Security Agency (CISA) added it to its catalog of flaws known to be used in attacks on 23 Oct 2024.[1]
Fortinet FortiManager 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. Fortinet has published a fix or advice.
Description
CISA calls it a missing authentication in Fortinet FortiManager. In its words: “Fortinet FortiManager contains a missing authentication vulnerability in the fgfmd daemon that allows a remote, unauthenticated attacker to execute arbitrary code or commands via specially crafted requests.”[1]
The CVE record adds: “A missing authentication for critical function in FortiManager 7.6.0, FortiManager 7.4.0 through 7.4.4, FortiManager 7.2.0 through 7.2.7, FortiManager 7.0.0 through 7.0.12, FortiManager 6.4.0 through 6.4.14, FortiManager 6.2.0 through 6.2.12, Fortinet FortiManager Cloud 7.4.1 through 7.4.4, FortiManager Cloud 7.2.1 through 7.2.7, FortiManager Cloud 7.0.1 through 7.0.12, FortiManager Cloud 6.4.1 through 6.4.7 allows attacker to execute arbitrary code or commands via specially crafted requests.”[2]
The underlying weakness is missing authentication (CWE-306), in MITRE’s list of common software weaknesses.
It scores 9.8 out of 10 on the Common Vulnerability Scoring System, which rates it critical, scored by NVD using CVSS 3.1.[2]
Affected versions
NVD’s record doesn’t list version ranges for it; Fortinet’s advisory has them[3]. CISA names the product as Fortinet FortiManager.
Most families won’t have Fortinet FortiManager; it’s for whoever looks after IT at work.
Exploitation
CISA added it to its catalog of known exploited vulnerabilities on 23 Oct 2024, within a day of it being made public. CISA lists a flaw only when it has reliable evidence of it being exploited, and gave US federal agencies until 13 Nov 2024 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 95%. That’s in the top 1% 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
Fortinet 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.Fortinet FortiManager 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 13 Nov 2024 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.
