+This week highlights multiple critical Cisco vulnerabilities (CVE-2025-20363, CVE-2025-20333, CVE-2025-20362). This flaw stems from improper input validation in HTTP(S) requests. An authenticated VPN user could send crafted requests to execute code as root, potentially compromising the device.
+The initial two were made available on September 28, with a third rule added today, October 7, for more robust protection. 
+
+* Cisco (CVE-2025-20333, CVE-2025-20362, CVE-2025-20363): Multiple vulnerabilities that could allow attackers to exploit unsafe deserialization and input validation flaws. Successful exploitation may result in arbitrary code execution, privilege escalation, or command injection on affected systems.

+Cisco (CVE-2025-20333, CVE-2025-20362, CVE-2025-20363): Exploitation enables attackers to escalate privileges or achieve remote code execution via command injection.
