From Exploited flaws, HARD’s guide to the flaws being used in attacks · Checked
This article is about a flaw in AMI MegaRAC SPx. For every flaw being used in attacks, see Exploited flaws.

CVE-2024-54085 is a security flaw in AMI MegaRAC SPx. Attackers can get into AMI MegaRAC SPx without a valid password. The US Cybersecurity and Infrastructure Security Agency (CISA) added it to its catalog of flaws known to be used in attacks on 25 Jun 2025.[1]

AMI MegaRAC SPx 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. Fixed in version 12.7 and 13.5 of MegaRAC-SPx.

Description

CISA calls it an authentication bypass by spoofing in AMI MegaRAC SPx. In its words: “AMI MegaRAC SPx contains an authentication bypass by spoofing vulnerability in the Redfish Host Interface. A successful exploitation of this vulnerability may lead to a loss of confidentiality, integrity, and/or availability.”[1]

The underlying weakness is authentication bypass by spoofing (CWE-290), in MITRE’s list of common software weaknesses.[2]

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]

Most families won’t have AMI MegaRAC SPx; it’s for whoever looks after IT at work.

Exploitation

CISA added it to its catalog of known exploited vulnerabilities on 25 Jun 2025, 106 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 16 Jul 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 61%. That’s in the top 1% of the flaws it scores.[4]

CISA assesses it as automatable: attackers can run it against many targets at once.

CISA doesn’t say who was attacked, or how.

Fix

AMI has published a fix or advice.[3] CISA’s required action: “Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.”[1]

  1. Check whether you use it.AMI MegaRAC SPx 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.
  2. Send this page to your IT person.Ask them to confirm it’s fixed (fixed in version 12.7 and 13.5 of MegaRAC-SPx), or not in use. CISA gave US government agencies until 16 Jul 2025 to fix it.
  3. 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.
