What it is
The record does not classify the weakness yet; the description below says what the reporter found.
How it is reached
An attacker can exploit it with physical access to the device, without an account, and nobody has to click anything.
What an attacker gains
A successful attack can read the data it protects and change data or behaviour.
Is it being exploited?
There is no public report of exploitation yet. EPSS estimates a 0.14% chance of exploitation activity in the next 30 days, higher than 4% of scored CVEs.
What to do
- Upgrade Yealink UVC40 E2 to 319.410.0.71 or later.
Description from NVD
On Yealink UVC40 E2 devices before 319.410.0.71, an attacker with short-term physical access can steal Wi‑Fi credentials via the USB interface. Sensitive data within the firmware configuration can be abused to gain root privileges on the device. Within Wi‑Fi coverage, the attacker may perform audio and video eavesdropping with no LED alert from the device.
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
- Yealink UVC40 E2. Start from where it runs and what it is connected to.
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.
Questions to answer about your own systems
- Where does Yealink UVC40 E2 run in your systems, and at which version?
- Which of those devices sit where outsiders can touch them?
- What can it reach once compromised: which data stores, secrets and services?
