CVE-2025-1074: Webkul QloApps CSRF Vulnerability

CVE-2025-1074 Overview

CVE-2025-1074 is a cross-site request forgery (CSRF) vulnerability affecting Webkul QloApps version 1.6.1. The flaw resides in the logout function reachable through the /en/?mylogout URL handler. Attackers can craft a malicious page that, when visited by an authenticated user, forces the browser to submit a logout request without user consent. The exploit has been publicly disclosed and can be launched remotely over the network. Webkul was notified prior to disclosure and is working on a fix. The vulnerability is tracked under CWE-352: Cross-Site Request Forgery.

Critical Impact
Remote attackers can forcibly log out authenticated QloApps users by luring them to a malicious page, disrupting availability of the hotel reservation platform session.

Technical Details for CVE-2025-1074

Vulnerability Analysis

QloApps is an open-source hotel booking and reservation management platform developed by Webkul. Version 1.6.1 exposes a logout endpoint at /en/?mylogout that terminates the active session upon receipt of a GET request. The endpoint does not require a synchronizer token, referer validation, or any other anti-CSRF control. Any cross-origin request that reaches the endpoint while a user holds a valid session cookie will succeed in destroying that session.

While the impact is limited to session termination rather than data modification, forced logouts can disrupt reservation workflows, back-office administration, and customer-facing operations. Repeated exploitation against staff accounts can create a targeted denial-of-service condition against the booking system.

Root Cause

The root cause is missing CSRF protection on a state-changing endpoint. Session termination is a state change that must be authorized through an unpredictable token bound to the user's session. QloApps 1.6.1 accepts the logout action based solely on the presence of an authentication cookie, which browsers attach automatically to any cross-site request.

Attack Vector

An attacker hosts a page containing an embedded resource, such as an <img> tag or hidden iframe, that points to https://<victim-qloapps-host>/en/?mylogout. When an authenticated QloApps user visits the attacker-controlled page, the browser issues the request with the session cookie attached. The QloApps server processes the request and terminates the session. No user interaction beyond visiting the malicious page is required, and the attack works across origins because the endpoint accepts simple GET requests.

A public proof-of-concept is available in the GitHub PoC repository and further technical detail is catalogued in VulDB #294834.

Detection Methods for CVE-2025-1074

Indicators of Compromise

Unusually high volume of requests to /en/?mylogout from mixed or external referers
Logout events immediately preceded by navigation from untrusted external domains in web server logs
User reports of unexpected session termination while browsing unrelated sites
Repeated logout entries for the same user within short time windows

Detection Strategies

Parse web server access logs for GET requests to /en/?mylogout and correlate the Referer header against the QloApps origin
Alert on any request to the logout endpoint whose referer is empty, cross-origin, or absent from an allowlist
Compare session termination events against normal user activity patterns to identify forced logouts

Monitoring Recommendations

Enable verbose HTTP request logging on the QloApps web server, including referer and origin headers
Forward web and application logs to a centralized analytics platform for correlation across users and time
Track logout-to-login ratios per account and alert on anomalies

How to Mitigate CVE-2025-1074

Immediate Actions Required

Restrict access to the QloApps administrative interface to trusted IP ranges or VPN networks until a vendor patch is released
Deploy a web application firewall rule that blocks requests to /en/?mylogout lacking a same-origin Referer or Origin header
Instruct administrators to log out of QloApps sessions before browsing other sites and to use isolated browser profiles for administrative work
Monitor the Webkul QloApps GitHub repository for the security patch

Patch Information

At the time of publication no vendor patch is available. Webkul has acknowledged the report and is working on a resolution. Administrators should track the vendor advisory channels and apply the update to QloApps as soon as it is released.

Workarounds

Configure the session cookie with the SameSite=Strict or SameSite=Lax attribute to prevent the browser from sending it on cross-site requests
Add a reverse-proxy rule that requires a matching Origin header on requests to logout endpoints
Enforce short session timeouts to reduce the window of exploitability

bash

# Example nginx rule blocking cross-origin logout requests
location ~ ^/en/\?mylogout {
    if ($http_origin !~* ^https?://qloapps\.example\.com$) {
        return 403;
    }
    proxy_pass http://qloapps_backend;
}
