SNMP has always been one of the quiet but crucial components of network management. It helps administrators monitor devices, automate configurations, and keep operations running smoothly. On Sept. 24, 2025, Cisco disclosed a high-severity vulnerability, identified as CVE-2025-20352, affecting the SNMP implementation in its IOS and IOS XE software. This issue allows attackers with valid SNMP credentials to cause a denial of service or execute arbitrary code on the affected devices.

Welcome to The researcher’s desk – a content series where the Detectify security research team conducts a technical autopsy on vulnerabilities that are particularly interesting, complex, or persistent. For this issue, we look at CVE-2025-64446, a critical authentication bypass that has been actively exploited in the wild, targeting Fortinet’s Web Application Firewall (WAF) product, FortiWeb.

LevelBlue Labs is tracking a severe vulnerability in Windows Server Update Services (WSUS), CVE-2025-59287, that allows attackers to remotely execute code without authentication and is being exploited by threat actors to compromise vulnerable Windows Server users.

Welcome to The researcher’s desk – a content series where the Detectify security research team conducts a technical autopsy on vulnerabilities that are particularly interesting, complex, or persistent. The goal here is not to report the latest research (for which you can refer to the Detectify release log); it is to take a closer look at certain vulnerabilities, regardless of their disclosure date, that still offer critical lessons.

A critical zero-day, CVE-2025-64446, path-traversal vulnerability in Fortinet FortiWeb, the company’s Web Application Firewall (WAF), is being actively exploited in the wild to create unauthorized administrator accounts on exposed systems. This flaw allows unauthenticated attackers to gain complete administrator access to affected devices.

On November 13, 2025, open source reporting began detailing active exploitation of a silently patched Fortinet FortiWeb vulnerability. The flaw is a path traversal issue in the FortiWeb web application firewall (WAF) that allows an unauthenticated threat actor to create new administrative users on exposed devices. The following day, November 14, Fortinet officially addressed the vulnerability in an advisory, tracking it as CVE‑2025‑64446.

AI has collapsed the vulnerability exploit lifecycle. Adversaries now discover, weaponize, and exploit exposures across hybrid environments in minutes — chaining together misconfigurations, unpatched systems, and stolen credentials to gain rapid access and move laterally across environments. For defenders, the speed of the adversary changes everything.
