What it is
A function that should require sign-in can be called by anyone.
How it is reached
An attacker can exploit it by someone who can already run code or sign in on the machine, with an ordinary user account, and nobody has to click anything.
What an attacker gains
A successful attack can change data or behaviour. In practice, this kind of flaw lets an attacker act as a signed-in user, or an administrator, without valid credentials.
Is it being exploited?
There is no public report of exploitation yet.
What to do
- Apply the update for your edition of Microsoft Windows 10. Fixed builds: Windows 10 Version 1607: 10.0.14393.9688; Windows 10 Version 1809: 10.0.17763.9487; Windows 10 Version 21H2: 10.0.19044.7846; Windows 10 Version 22H2: 10.0.19045.7846. Other affected products have their own fixed versions on this page.
- Limit who can run code or sign in on the hosts that run it.
Description from NVD
Missing authentication for critical function in Microsoft Account allows an authorized attacker to perform tampering locally.
What this means for your architecture.
A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.
Components it touches
- Sign-in, session and token handling. The flaw sits between anonymous callers and authenticated sessions.
- Identity providers and SSO. The flaw sits between anonymous callers and authenticated sessions.
Trust boundaries in play
- Host boundary. The attacker needs a foothold on the machine first; the flaw turns a small foothold into a bigger one.
- Between anonymous callers and authenticated sessions. An attacker who crosses it can act as a signed-in user, or an administrator, without valid credentials.
Questions to answer about your own systems
- Where does Microsoft Windows 10 run in your systems, and at which version?
- Which of those hosts also run code or users you do not fully trust?
- What can it reach once compromised: which data stores, secrets and services?
