CVE-2026-25605 in SICAM SIAPP SDK
Summary
by MITRE • 03/10/2026
A vulnerability has been identified in SICAM SIAPP SDK (All versions < V2.1.7). The affected application performs file deletion without properly validating the file path or target. An attacker could delete files or sockets that the affected process has permission to remove, potentially resulting in denial of service or service disruption.

The vulnerability identified in the SICAM SIAPP SDK affects all versions prior to V2.1.7 and represents a critical path traversal and file deletion flaw that undermines the application's security posture. This vulnerability stems from inadequate input validation mechanisms within the file deletion functionality, allowing malicious actors to manipulate file paths and execute unauthorized deletion operations. The affected system operates under the assumption that file operations are safe when they should be rigorously validated against potential attack vectors. This weakness creates a direct pathway for privilege escalation and system disruption through carefully crafted file deletion requests.
The technical implementation of this vulnerability resides in the application's failure to properly sanitize and validate file paths before executing deletion operations. When the SDK processes file deletion requests, it does not adequately verify that the target file path falls within the expected directory boundaries or that the operation is authorized for the requesting entity. This lack of proper validation creates a path traversal condition that enables attackers to specify arbitrary file paths that may point to system-critical files or sockets. The vulnerability specifically manifests when the application accepts user-controllable input without proper sanitization, leading to potential deletion of files that the process has sufficient permissions to remove. This flaw directly maps to CWE-22 Path Traversal and CWE-77 Path Traversal, both of which are fundamental security weaknesses that have been extensively documented in the cybersecurity community.
The operational impact of this vulnerability extends beyond simple denial of service scenarios to encompass potential system compromise and service disruption across industrial control systems that rely on SICAM SIAPP SDK. An attacker who successfully exploits this vulnerability could delete critical system files, configuration data, or socket connections that would result in complete service outages or system instability. The disruption could manifest as application crashes, loss of operational data, or complete system unavailability, particularly in environments where industrial automation systems depend on continuous operation. This vulnerability is particularly concerning in industrial settings where the SICAM SIAPP SDK may be used in critical infrastructure applications, as the impact of service disruption could extend to physical safety and operational continuity. The ATT&CK framework categorizes this vulnerability under T1489, which covers "Service Stop" and T1070, which addresses "Indicator Removal on Host," highlighting the potential for both immediate disruption and post-exploitation cleanup activities.
Mitigation strategies for this vulnerability should prioritize immediate software updates to version 2.1.7 or later, which contain the necessary patches to address the file validation flaws. Organizations should implement comprehensive input validation measures that enforce strict path validation and ensure that all file operations are performed within controlled directories. Additional protective measures include implementing proper access controls and privilege separation, ensuring that applications operate with the minimal necessary permissions to perform their functions. Network segmentation and monitoring should be deployed to detect unusual file deletion patterns that may indicate exploitation attempts. Security teams should also conduct thorough code reviews of any custom implementations that interact with the SDK to identify potential similar vulnerabilities in application logic. Regular vulnerability assessments and penetration testing should be performed to ensure that the mitigation measures remain effective against evolving threat landscapes. The implementation of file integrity monitoring systems can provide additional detection capabilities for unauthorized file modifications that may result from exploitation of this vulnerability.
