Which versions of Esselink.nu Esselink.nu Settings are affected by CVE-2025-52793?

A Cross-Site Request Forgery (CSRF) vulnerability affecting Esselink.nu Settings versions through 2.94 allows attackers to perform unauthorized actions on behalf of authenticated users.

How to fix or mitigate CVE-2025-52793?

Within 24 hours: Inventory all Esselink.nu Settings deployments and document current version numbers; notify affected teams to avoid clicking suspicious links while authenticated. Within 7 days: Implement Web Application Firewall (WAF) rules to detect and block CSRF attacks (validate referrer headers, implement SameSite cookie policies); review and harden session management controls. Within 30 days: Monitor vendor communications for patch availability; conduct security awareness training on CSRF attacks; consider disabling the affected Settings feature if business operations permit until patching is available.

DescriptionCVE.org

Cross-Site Request Forgery (CSRF) vulnerability in Esselink.nu Esselink.nu Settings allows Reflected XSS. This issue affects Esselink.nu Settings: from n/a through 2.94.

AnalysisAI

CVE-2025-52793 is a Cross-Site Request Forgery (CSRF) vulnerability in Esselink.nu Settings that enables reflected Cross-Site Scripting (XSS) attacks. The vulnerability affects Esselink.nu Settings versions up to and including 2.94, allowing unauthenticated remote attackers to perform actions on behalf of users and inject malicious scripts with minimal user interaction. With a CVSS score of 7.1 and network-based attack vector, this vulnerability poses a moderate-to-significant risk to affected installations, particularly if actively exploited or if public proof-of-concept code becomes available.

Technical ContextAI

This vulnerability combines two distinct vulnerability classes: CSRF (CWE-352) and reflected XSS. The root cause stems from inadequate CSRF token validation and insufficient input sanitization in Esselink.nu Settings web application parameters. Reflected XSS occurs when user-supplied input is echoed back in HTTP responses without proper HTML encoding or output escaping. The vulnerability likely exists in settings pages or administrative interfaces where configuration parameters are processed. The CVSS vector (AV:N/AC:L/PR:N/UI:R) indicates the attack requires network access, low complexity, no privileges, and user interaction (clicking a malicious link). The combination enables attackers to craft URLs containing both CSRF payloads and XSS injections that execute in the victim's browser context when visited.

RemediationAI

Upgrade Esselink.nu Settings to a version beyond 2.94 immediately (vendor should release patched version 2.95 or later). 2. If immediate patching is not possible, implement Web Application Firewall (WAF) rules to block requests containing common XSS payloads and CSRF attack patterns. 3. Enforce Content Security Policy (CSP) headers to prevent reflected XSS execution. 4. Implement SameSite cookie attributes (SameSite=Strict or SameSite=Lax) to mitigate CSRF attacks. 5. Validate and sanitize all user inputs server-side using allowlists. 6. Ensure all state-changing operations implement anti-CSRF tokens (synchronizer tokens or double-submit cookies) with proper validation. 7. Monitor access logs for suspicious patterns targeting settings pages. Contact Esselink.nu vendor support for specific patch availability and timeline.
