Why this priority: Medium severity, with no exploitation signal.
Published · Updated · NVD status: Deferred
What it is
Sensitive data crosses the network unencrypted.
How it is reached
An attacker can exploit it from the same local network segment, without an account, but someone has to act first, such as opening a file or following a link.
What an attacker gains
The direct impact is limited: partial access to data or a partial outage. In practice, this kind of flaw lets an attacker read or tamper with traffic, or pass a forged message as genuine.
Is it being exploited?
CISA's SSVC assessment notes a public proof of concept. EPSS estimates a 0.11% chance of exploitation activity in the next 30 days, higher than 1% of scored CVEs.
What to do
- Upgrade Shenzhen Shine Industrial Co., Ltd. VitaFit to 2.8.1.0 or later.
- Segment the networks that can reach it.
- Warn the people who use it, and filter files and links on the way in.
Description from NVD
VitaFit Android application (com.vt.vitafit) before 2.8.1.0 contains a cleartext traffic vulnerability that allows network-based attackers to intercept or modify unencrypted HTTP communications due to the absence of an Android network security configuration. Attackers on an untrusted network can manipulate support content displayed to the user by tampering with unencrypted HTTP traffic between the app and server.
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
- TLS termination and service-to-service channels. The flaw sits on the network path between clients and services.
- Signature checks. The flaw sits on the network path between clients and services.
Trust boundaries in play
- Local network segment. The attacker must share a network segment with the target.
- People who open files and links. Mail, chat and browsers are the delivery path.
- On the network path between clients and services. An attacker who crosses it can read or tamper with traffic, or pass a forged message as genuine.
Questions to answer about your own systems
- Where does Shenzhen Shine Industrial Co., Ltd. VitaFit run in your systems, and at which version?
- Which network segments can reach them?
- What can it reach once compromised: which data stores, secrets and services?
