CVE-2024-3777 is a critical severity vulnerability (CVSS 9.8) in Ai3 QbiBot. The password reset feature lacks access control, so unauthenticated remote attackers can reset any user's password. The record cites a TWCERT notice. Below you will find the affected versions, how to check your exposure, and a short list of steps to take now.
What's affected
- Ai3 QbiBot. The record's product data shows no specific version, so assume all versions until the vendor says otherwise.
Severity in the record: Critical, CVSS 9.8, vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H. In plain terms: over the network, no privileges required, no user interaction. Weakness class: CWE-306, missing authentication for a critical function.
Fixed version: The record cites a TWCERT notice. Check it for the fixed release.
The record's KEV flag is false, so this CVE is not in the CISA Known Exploited Vulnerabilities catalog, and no source reviewed here reports exploitation in the wild.
How to check if you're exposed
- Inventory where Ai3 QbiBot is deployed, including test and forgotten servers.
- Search your servers and container images for the product name and compare the version against the affected list above.
- If you cannot confirm the version, treat the installation as exposed until the vendor says otherwise.
What to do now
- Apply the vendor patch or updated version.
- Until then, restrict network access to the service.
- Force a credential reset and review sign in activity for accounts that may have been touched.
- Record the decision in your tracker with the CVE id and the date, so the next audit can see what you did about CVE-2024-3777.
Why it matters
Some operations, such as resetting a password, must only run for a caller who has proven who they are or holds a valid reset token. When the function is reachable without that proof, any visitor can use it. The fix is to require an authenticated session or a single use, time limited token tied to the account owner.
An account takeover through the reset flow is among the worst outcomes in an application, because it hands the attacker the real user's identity. With a score of 9.8 the record rates it Critical. Review logs for reset requests that you cannot explain, and consider forcing resets for administrator accounts.
Look up the entry on Gold to see how it connects to other advisories, and use reachability analysis to separate the components that actually call vulnerable code from the ones that merely sit in your inventory.
Quick check
What should I do about accounts that may have been taken over?
Force a password reset for accounts, starting with administrators, and review recent sign ins and changes for actions the owners did not make.
Is CVE-2024-3777 in the CISA KEV catalog?
No. The record's KEV flag is false.
