Description

A vulnerability has been identified in SIMATIC WinCC OA V3.15 (All versions), SIMATIC WinCC OA V3.16 (All versions < V3.16 P035), SIMATIC WinCC OA V3.17 (All versions < V3.17 P024), SIMATIC WinCC OA V3.18 (All versions < V3.18 P014). The affected component allows to inject custom arguments to the Ultralight Client backend application under certain circumstances. This could allow an authenticated remote attacker to inject arbitrary parameters when starting the client via the web interface (e.g., open attacker chosen panels with the attacker's credentials or start a Ctrl script).

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
