CVE-2025-14577 in NCP
Summary
by MITRE • 02/24/2026
Slican NCP/IPL/IPM/IPU devices are vulnerable to PHP Function Injection. An unauthenticated remote attacker is able to execute arbitrary PHP commands by sending specially crafted requests to /webcti/session_ajax.php endpoint.
This issue was fixed in version 1.24.0190 (Slican NCP) and 6.61.0010 (Slican IPL/IPM/IPU).

The vulnerability identified as CVE-2025-14577 affects Slican Network Control Panel and Integrated Processing Layer devices, specifically targeting the webcti/session_ajax.php endpoint. This represents a critical security flaw that allows unauthenticated remote code execution through PHP function injection techniques. The affected devices include various Slican product lines such as NCP, IPL, IPM, and IPU systems, which are commonly deployed in industrial and network control environments where security is paramount.
The technical flaw stems from improper input validation and sanitization within the webcti/session_ajax.php script, which processes user-supplied data without adequate security measures. Attackers can exploit this weakness by crafting malicious HTTP requests that inject PHP functions directly into the application's execution context. This type of vulnerability falls under CWE-94, which describes "Improper Control of Generation of Code" and is classified as a code injection attack vector. The vulnerability allows remote attackers to execute arbitrary PHP commands with the privileges of the web server process, potentially leading to complete system compromise.
The operational impact of this vulnerability is severe and far-reaching for organizations using Slican devices in their infrastructure. An unauthenticated attacker can gain full control over affected systems, enabling them to execute malicious code, access sensitive data, modify system configurations, and potentially use the compromised devices as launch points for further attacks within the network. The vulnerability's remote exploitability means that attackers do not require physical access or valid credentials to leverage this weakness, making it particularly dangerous in industrial control environments where network segmentation may be limited. This vulnerability directly maps to ATT&CK technique T1059.007, which covers "Command and Scripting Interpreter: PHP," and represents a significant risk to operational technology environments.
Organizations should immediately implement mitigation strategies including updating to the patched versions 1.24.0190 for Slican NCP and 6.61.0010 for Slican IPL/IPM/IPU devices. Network administrators should also consider implementing firewall rules to restrict access to the vulnerable endpoint, particularly in environments where the web interface is exposed to untrusted networks. Additional protective measures include monitoring network traffic for suspicious requests to the session_ajax.php endpoint and implementing web application firewalls to detect and block malicious payloads. The vulnerability demonstrates the critical importance of keeping industrial control systems updated and highlights the need for robust input validation practices in web applications. Organizations should conduct comprehensive security assessments of their Slican device deployments and consider implementing network segmentation to limit the potential impact of successful exploitation attempts.
