What it is
Credentials are built into the product, so anyone who knows them can sign in to every install.
How it is reached
An attacker can exploit it over the network, without an account, and nobody has to click anything.
What an attacker gains
A successful attack can read the data it protects. In practice, this kind of flaw lets an attacker sign in with credentials the vendor shipped or stored unprotected.
Is it being exploited?
There is no public report of exploitation yet.
What to do
- No fixed version is listed yet. Find every place tongcheng-security-team NextScan runs, watch the references for a fix, and plan a replacement if it is no longer supported.
- While there is no fix, keep it off the internet or behind a VPN, allowlist or authenticating proxy.
Description from NVD
NextScan 1.1.0 through 1.2.0 contains hardcoded HTTP Basic Auth credentials in ns-admin's AuthAgent and AuthExternal routers that allow unauthenticated attackers to access protected APIs. Attackers can call /agent/config to obtain Redis passwords, etcd details and the server token, and impersonate scan nodes via registration, heartbeat and logging endpoints.
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
- Credentials kept in code, configuration, images or firmware. The flaw sits between a stored secret and anyone who can read where it is kept.
Trust boundaries in play
- Internet-facing entry points. No account is needed. Any instance reachable from outside your perimeter, through a load balancer, gateway, VPN or exposed admin port, is in scope.
- Between a stored secret and anyone who can read where it is kept. An attacker who crosses it can sign in with credentials the vendor shipped or stored unprotected.
Questions to answer about your own systems
- Where does tongcheng-security-team NextScan run in your systems, and at which version?
- Which of those instances can be reached from the internet or partner networks?
- What can it reach once compromised: which data stores, secrets and services?
