A vulnerability has been identified in SINEMA Remote Connect Server (All versions < V3.1). The system images for installation or update of the affected application contain unit test scripts with sensitive information. An attacker could gain information about testing architecture and also tamper with test configuration.

Weakness

The product uses physical debug or test interfaces with support for multiple access levels, but it assigns the wrong debug access level to an internal asset, providing unintended access to the asset from untrusted debug agents.

Affected Software

Name Vendor Start Version End Version
Sinema_remote_connect_server Siemens * 3.1 (excluding)

Extended Description

Debug authorization can have multiple levels of access, defined such that different system internal assets are accessible based on the current authorized debug level. Other than debugger authentication (e.g., using passwords or challenges), the authorization can also be based on the system state or boot stage. For example, full system debug access might only be allowed early in boot after a system reset to ensure that previous session data is not accessible to the authenticated debugger. If this protection mechanism does not ensure that internal assets have the correct debug access level during each boot stage or change in system state, an attacker could obtain sensitive information from the internal asset using a debugger.

Potential Mitigations

  • For security-sensitive assets accessible over debug/test interfaces, only allow trusted agents.
