CVE-2022-45092: CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in Siemens SINEC INS
A vulnerability has been identified in SINEC INS (All versions < V1.0 SP2 Update 1). An authenticated remote attacker with access to the Web Based Management (443/tcp) of the affected product, could potentially read and write arbitrary files from and to the device's file system. An attacker might leverage this to trigger remote code execution on the affected component.
AI Analysis
Technical Summary
CVE-2022-45092 is a critical path traversal vulnerability (CWE-22) affecting Siemens SINEC INS versions prior to V1.0 SP2 Update 1. The vulnerability exists in the web-based management interface accessible over TCP port 443, which requires authentication. An attacker with valid credentials can exploit improper limitation of pathname inputs to read and write arbitrary files on the device's file system. This can lead to remote code execution (RCE) on the affected component, allowing the attacker to execute arbitrary commands with the privileges of the application. The vulnerability arises because the software does not properly sanitize or restrict pathname inputs, enabling traversal outside intended directories. The CVSS v3.1 score is 9.9 (critical), reflecting the network attack vector, low attack complexity, required privileges, no user interaction, and high impact on confidentiality, integrity, and availability. Although no known exploits are reported in the wild yet, the potential for severe impact is significant due to the ability to execute code remotely and manipulate system files. Siemens SINEC INS is an industrial network management product used in critical infrastructure and industrial environments, increasing the risk profile of this vulnerability.
Potential Impact
For European organizations, especially those in industrial sectors such as manufacturing, energy, utilities, and critical infrastructure, this vulnerability poses a severe risk. Exploitation could lead to unauthorized disclosure of sensitive configuration files, manipulation or deletion of critical system files, and full system compromise via remote code execution. This could disrupt industrial control systems, cause operational downtime, safety hazards, and potentially lead to cascading failures in critical infrastructure. Given the reliance on Siemens products in European industrial environments, the impact could extend to national critical infrastructure, affecting energy grids, transportation systems, and manufacturing plants. The confidentiality, integrity, and availability of these systems are at high risk, potentially resulting in financial losses, regulatory penalties, and damage to reputation.
Mitigation Recommendations
1. Immediate upgrade to Siemens SINEC INS version V1.0 SP2 Update 1 or later, where the vulnerability is patched. 2. Restrict access to the web-based management interface (port 443) using network segmentation, firewall rules, and VPNs to limit exposure to trusted administrators only. 3. Implement strong authentication mechanisms and monitor for unusual login activity to detect potential misuse of credentials. 4. Employ file integrity monitoring on affected devices to detect unauthorized file changes. 5. Regularly audit and review user accounts with access to the management interface to ensure least privilege principles. 6. If patching is not immediately possible, consider disabling the web management interface or restricting it to isolated management networks. 7. Conduct penetration testing and vulnerability scanning focused on path traversal and file manipulation vulnerabilities in industrial network devices. 8. Maintain up-to-date incident response plans tailored to industrial control system environments to quickly contain and remediate any exploitation attempts.
