A template injection vulnerability was discovered in the Dashboards functionality due to improper validation of an input parameter
What this means
This is rated medium severity (5.3 out of 10). There is no confirmed exploitation of it yet.
Full vendor description
An improper certificate/host key validation vulnerability was discovered in the Smart Polling functionality, which established encrypted connections to target devices without validating the remote host's identity, and no option was provided to enable it. A man-in-the-middle attacker positioned between a sensor and a polled device can, during a polling session, impersonate the device and intercept the communication, including the credentials used to access it. The captured credentials can then be replayed to authenticate against the device itself or against other devices sharing the same credentials, allowing the attacker to access and tamper with the device's data and to disrupt its operations.
Scoring and exploitation
Exploitable over the network without any account, under specific conditions, but only if a user takes an action, such as opening a file or link. High impact on subsequent confidentiality; low on subsequent integrity and subsequent availability.
