Apache Tomcat continues to play a central role in hosting Java-based web applications across enterprises, cloud services, and government systems. Its reliability and lightweight architecture make it a go-to choice for developers, but its ubiquity also means that a single vulnerability can have widespread security implications. CVE-2025-55752, disclosed in late 2025, highlights how a subtle processing regression can evolve into a high-impact vulnerability under the right conditions.

The best part about my job is that I sometimes get to make some controversial statements. Well, as controversial as things can be in a niche area of cybersecurity like “what is a reasonable measure of vulnerability risk?” Along with my colleague Sander Vinberg we got to explore this question earlier this year at the second Annual VulnCon conference in Raleigh. Even though it’s only been held twice, it is quickly becoming one of my favorite conferences.

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.
