Cisco has disclosed multiple vulnerabilities affecting its security product portfolio, including Secure Firewall Management Center, Firepower devices, ASA Software, Firewall Threat Defense, Identity Services Engine, and IOS/IOS XE platforms. The most severe vulnerability (CVE-2025-20265) allows unauthenticated remote attackers to inject arbitrary shell commands into Cisco Secure Firewall Management Center through the RADIUS subsystem, potentially leading to full system compromise.
The advisory encompasses over 30 vulnerabilities ranging from denial-of-service conditions to authentication bypasses and privilege escalation issues. Many affect the web-based management interfaces and VPN services across Cisco's firewall and threat defense products. Multiple IKEv2 implementation flaws could enable DoS attacks against IOS, IOS XE, ASA, and FTD platforms. Additional vulnerabilities involve packet inspection engines, certificate processing, NAT DNS inspection, and TLS 1.3 implementation weaknesses.
Cisco has not observed active exploitation of these vulnerabilities in the wild. The affected systems span multiple product versions, with exploitation dependent on specific configuration criteria rather than version numbers alone. Organizations are strongly advised to review Cisco's configuration guidance to determine exposure and apply available patches immediately after testing. The vulnerabilities primarily impact enterprise networks, government agencies, and critical infrastructure sectors relying on Cisco security infrastructure.

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 16,445 reports from 149 sources, 666 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.
