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
- Services that build database or directory queries. The flaw sits between the application and its data store.
- Databases. The flaw sits between the application and its data store.
- Application servers and the hosts they run on. The flaw sits between untrusted input and code or command execution.
- Template engines. The flaw sits between untrusted input and code or command execution.
Trust boundaries in play
- Authenticated network access. An account is needed, so exposure follows who can sign in: customers, partners or staff.
- Between the application and its data store. An attacker who crosses it can read or change records in the data store behind the application.
- Between untrusted input and code or command execution. An attacker who crosses it can run commands or code with the privileges of the affected service.
