Vulnerability from csaf_siemens - Published: 2026-10-13 00:00 - Updated: 2026-10-13 00:00A template injection vulnerability was discovered in the Dashboards functionality due to improper validation of an input parameter. An authenticated user with the required privileges can define a dashboard containing a malicious payload, or a victim can be socially engineered into importing a malicious dashboard. When the victim views or imports the dashboard, the payload executes in their browser context, allowing the attacker to modify application data or disrupt application availability.

An access control vulnerability was discovered in the Credentials Manager functionality due to insufficient validation of user privileges. A remote authenticated user with limited privileges can view a limited subset of the available entries in the Credentials Manager. The actual credential values are not directly visible, but the user can delete entries or edit their properties. An attacker who deletes or edits an entry can disrupt authentication for dependent devices, and one who manipulates an entry's configuration may be able to indirectly obtain the credentials.
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.
An access control vulnerability was discovered in the Smart Polling configuration functionality due to insufficient validation of user privileges. An authenticated user with limited privileges can remotely bypass the intended access control of the web management interface and modify the Smart Polling discovery configuration. This allows the attacker to disrupt the visibility of assets in the monitored network.
A cross-site request forgery vulnerability was discovered in the login functionality (both standard and SAML) due to missing validation of the anti-CSRF token. An attacker with a valid account can trick a victim into unknowingly authenticating with the attacker's credentials. Any operation performed by the victim in this state is attributed to the attacker's account, compromising the integrity of the audit trail.
