CVE-2024-31854 in SICAM TOOLBOX II
Summary
by MITRE • 07/08/2025
A vulnerability has been identified in SICAM TOOLBOX II (All versions < V07.11). During establishment of a https connection to the TLS server of a managed device, the affected application doesn't check device's certificate common name against an expected value. This could allow an attacker to execute an on-path network (MitM) attack.

The vulnerability identified as CVE-2024-31854 affects SICAM TOOLBOX II software across all versions prior to V07.11, representing a critical security flaw in the cryptographic communication protocol implementation. This issue manifests during the establishment of HTTPS connections to TLS servers of managed devices, where the application fails to validate the certificate's common name against expected values. The absence of proper certificate validation creates a significant security gap that undermines the integrity of the communication channel between the management application and target devices. This flaw directly impacts the authentication mechanism that should ensure the legitimacy of the server being connected to, effectively removing a crucial layer of security that protects against unauthorized access and data interception.
The technical nature of this vulnerability aligns with CWE-295, which specifically addresses "Improper Certificate Validation," and represents a failure in the certificate validation process that should occur during TLS handshake operations. The flaw enables attackers to perform man-in-the-middle attacks by exploiting the lack of certificate common name verification, allowing them to intercept and potentially modify communications between the SICAM TOOLBOX II application and managed devices. This vulnerability operates at the transport layer security level where the application should validate that the certificate presented by the server matches the expected hostname or domain name, but instead accepts any valid certificate regardless of its intended target. The implementation bypasses standard security protocols that ensure the authenticity of network endpoints through proper certificate chain validation.
The operational impact of this vulnerability extends beyond simple network interception, as it provides attackers with potential access to sensitive operational data and control functions within managed devices. An attacker positioned in the network path between the SICAM TOOLBOX II application and target devices could present a fraudulent certificate that appears valid to the application, thereby gaining unauthorized access to device management interfaces, configuration data, and potentially executing commands on the managed devices. This risk is particularly concerning in industrial control environments where SICAM TOOLBOX II is likely deployed, as it could enable attackers to compromise critical infrastructure operations, manipulate device settings, or gain persistent access to industrial systems. The vulnerability essentially removes the cryptographic assurance that communications are occurring with the intended device, creating an attack surface that could be exploited for lateral movement within network segments.
Mitigation strategies for CVE-2024-31854 should prioritize immediate upgrade to SICAM TOOLBOX II version V07.11 or later, which presumably contains the necessary certificate validation fixes. Organizations should also implement additional network security controls such as network segmentation, intrusion detection systems, and monitoring for suspicious certificate usage patterns. The implementation of certificate pinning mechanisms and enhanced network visibility tools can provide additional layers of protection against this specific attack vector. Security teams should conduct comprehensive network assessments to identify any devices or systems that may be vulnerable to this attack and establish monitoring procedures to detect potential man-in-the-middle activities. From an ATT&CK framework perspective, this vulnerability maps to techniques involving credential access and defense evasion, as attackers could use this flaw to establish persistent access to industrial control systems while avoiding detection through normal security monitoring procedures. Organizations should also consider implementing zero-trust network architectures that validate all communications regardless of their source or destination, reducing the impact of such certificate validation failures.
