Monitor7.8ICS-CERT ICSA-21-350-16Dec 16, 2021
Attack VectorLocal
Auth RequiredNone
ComplexityLow
User InteractionRequired
Summary
Syngo fastView contains buffer overflow and array indexing vulnerabilities (CWE-787, CWE-123) that could result in application crash or arbitrary code execution. The vulnerabilities are triggered when a user opens a malicious file within the application. These are not remotely exploitable and require local user interaction. No known public exploits currently exist. Siemens Healthineers has not released a patch for any version of the product.
What this means
What could happen
An attacker with local access could cause the application to crash or run arbitrary code on a system running syngo fastView, potentially disrupting diagnostic imaging workflows and compromising the integrity of medical image data.
Who's at risk
Healthcare IT staff and imaging technicians at facilities using Siemens syngo fastView for diagnostic image processing and review. Affected systems include workstations and servers running all versions of the application. This impacts clinical operations that depend on reliable image viewing and data integrity.
How it could be exploited
An attacker must trick a user into opening a malicious file (such as a crafted image or document) in syngo fastView on a system where the application is installed. The buffer overflow or logic flaw in the file parser would then execute the attacker's code or crash the application with elevated privileges.
Prerequisites
- Local access to a system with syngo fastView installed
- User interaction required to open a malicious file
- File must be opened within syngo fastView application
