CVE-2015-1595 in SPCanywhere
Summary
by MITRE
The Siemens SPCanywhere application for Android and iOS does not use encryption during lookups of system ID to IP address mappings, which allows man-in-the-middle attackers to discover alarm IP addresses and spoof servers by intercepting the client-server data stream.

The Siemens SPCanywhere mobile application for android and ios platforms contains a critical security flaw that compromises the confidentiality and integrity of network communications. This vulnerability specifically affects the application's handling of system identification and address resolution processes, creating a significant attack surface for malicious actors who can exploit the lack of proper encryption mechanisms. The flaw resides in the application's lookup functionality that maps system identifiers to ip addresses without implementing adequate cryptographic protection during data transmission.
The technical implementation of this vulnerability stems from the application's failure to employ encryption protocols when performing system id to ip address mapping operations. This creates an unencrypted communication channel that exposes sensitive network information to interception and manipulation. Attackers can leverage this weakness through man-in-the-middle attacks to capture and analyze the client-server data stream, thereby gaining access to critical alarm system ip addresses that would normally remain protected. The absence of encryption during these lookup operations violates fundamental security principles for mobile application development and network communication.
The operational impact of this vulnerability extends beyond simple information disclosure to encompass potential system compromise and unauthorized access to industrial control systems. When attackers successfully intercept the unencrypted data streams, they can discover the ip addresses of alarm systems and use this information to spoof servers, potentially gaining unauthorized access to critical infrastructure. This vulnerability directly undermines the security posture of organizations relying on Siemens SPCanywhere for monitoring and managing their industrial environments. The exposure of alarm system ip addresses creates opportunities for attackers to target specific network components and potentially disrupt operations.
The security implications of this vulnerability align with several common weakness enumerations including CWE-319, which addresses the exposure of sensitive information through improper encryption of network communications. Additionally, this flaw corresponds to ATT&CK technique T1046, which covers network service scanning, and T1566, which involves credential harvesting through phishing or network interception. Organizations using this application face increased risk of lateral movement within their networks and potential compromise of industrial control systems. The vulnerability also demonstrates poor adherence to security best practices for mobile application development, particularly regarding the protection of sensitive data in transit.
Mitigation strategies for this vulnerability should include immediate implementation of encryption protocols for all network communications within the application, particularly during system identification and address resolution processes. Organizations should consider implementing network segmentation and monitoring to detect anomalous traffic patterns that may indicate exploitation attempts. The application should be updated to enforce secure communication channels using industry-standard encryption protocols such as tls 1.2 or higher. Additionally, network administrators should implement intrusion detection systems to monitor for suspicious activity related to the discovered ip addresses and consider temporary network restrictions until proper encryption is implemented. Regular security assessments should be conducted to ensure that similar vulnerabilities are not present in other applications within the industrial control system environment.
