CVE-2025-64095 is a critical unauthenticated file-upload vulnerability affecting DNN (DotNetNuke) versions prior to 10.1.1. The flaw exists in the platform’s default HTML editor provider, where upload validation and authorization checks were insufficient. Attackers can upload files and overwrite existing content without credentials, enabling page defacement, malicious script injection, and in some environments stored cross-site scripting (XSS).

CVE-2025-55752 is a path traversal vulnerability in Apache Tomcat. It comes from a regression introduced during a past bug fix. Because of this flaw, Tomcat normalizes URLs before decoding them, which lets attackers craft requests that bypass access controls and reach restricted directories like /WEB-INF/ and /META-INF/. In deployments where HTTP PUT is enabled, an attacker could upload files through this path and potentially gain remote code execution (RCE).

Welcome to The researcher’s desk – a content series where the Detectify security research team will conduct 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.

In October 2025, Microsoft disclosed a critical remote code execution vulnerability (CVE-2025-59287) in Windows Server Update Services (WSUS), which enables unauthenticated attackers to gain full control over affected servers. WSUS is a central patch management tool in Windows environments, responsible for approving, distributing, and monitoring updates across corporate networks.

Security teams don’t struggle to find exposures – they struggle to fix them. The new Seemplicity AI Agents change that. Integrated into the Exposure Action Platform, they combine intelligence and automation to help teams move faster, stay aligned, and reduce risk. From clear findings and ownership mapping to guided fixes and executive insights, Seemplicity’s AI Agents make exposure management truly action-driven.

The Common Vulnerability Scoring System (CVSS) has been the industry’s go-to framework for assessing vulnerability severity for nearly two decades. It provides a standardized way to measure and communicate the technical impact of a vulnerability. As threat landscapes evolve and organizations mature in their vulnerability management practices, questions about its relevance and limitations persist. That even led to our co-founder, Scott Kuffer, writing a defense of the algorithm earlier this year.
