CERT Polska disclosed CVE-2025-14577, a critical PHP function injection vulnerability affecting Slican NCP, IPL, IPM, and IPU devices. The vulnerability allows unauthenticated remote attackers to execute arbitrary PHP commands by sending specially crafted requests to the /webcti/session_ajax.php endpoint. No authentication is required to exploit this flaw, making it a high-severity pre-authentication remote code execution vector.
The vulnerability was responsibly disclosed by researcher Dariusz Gońda and coordinated through CERT Polska's disclosure process. Slican has released patches addressing the issue: version 1.24.0190 for NCP devices and version 6.61.0010 for IPL/IPM/IPU devices. Organizations using affected Slican telecommunications equipment should prioritize patching immediately given the unauthenticated nature of the exploit.
This vulnerability represents a significant risk to telecommunications infrastructure, as successful exploitation would grant attackers full control over affected devices, potentially enabling network compromise, traffic interception, or use as a pivot point for further attacks.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,433 reports from 149 sources, 661 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
