CVE-2025-7133: Movie Ticket Booking System CSRF Flaw

CVE-2025-7133 Overview

CVE-2025-7133 is a cross-site request forgery (CSRF) vulnerability affecting CodeAstro Online Movie Ticket Booking System version 1.0. The flaw resides in an unspecified component of the application and can be triggered remotely without prior authentication. An attacker can craft a malicious web page that, when visited by an authenticated user, performs unwanted state-changing actions on the vulnerable application. The exploit has been publicly disclosed, increasing the risk of opportunistic abuse against exposed deployments. The weakness is tracked under CWE-352.

Critical Impact
Remote attackers can trick authenticated users into submitting attacker-controlled requests, resulting in unauthorized modifications to booking data or account state within the application.

Technical Details for CVE-2025-7133

Vulnerability Analysis

The application fails to validate the origin or authenticity of state-changing HTTP requests. Because sensitive actions rely solely on session cookies for authorization, browsers automatically attach those cookies to any request the user's browser is induced to send. An attacker who lures an authenticated user to a hostile page can therefore issue booking, profile, or administrative requests on the victim's behalf. User interaction is required, but no credentials or elevated privileges are needed on the attacker side. The public disclosure of exploitation details lowers the barrier for reuse across unpatched instances.

Root Cause

The root cause is missing anti-CSRF protection on sensitive endpoints, categorized as [CWE-352]. The application does not implement synchronizer tokens, double-submit cookies, SameSite cookie enforcement, or origin/referer validation. Any authenticated session is therefore treated as sufficient proof of user intent for state-changing operations.

Attack Vector

The attack vector is network-based and requires the victim to interact with attacker-controlled content, such as a link, image, or embedded form. The attacker hosts a page that auto-submits a request to the vulnerable application. When the authenticated victim loads the page, the browser forwards session cookies, and the server processes the forged action as legitimate. The vulnerability requires a valid user session on the target but no additional privileges.

No verified proof-of-concept code is published in the referenced advisories. See the VulDB entry and the GitHub project documentation for additional technical context.

Detection Methods for CVE-2025-7133

Indicators of Compromise

Booking, profile, or administrative changes performed by authenticated users without corresponding navigation events in access logs
HTTP requests to state-changing endpoints carrying Referer or Origin headers from untrusted third-party domains
Bursts of identical POST requests from multiple user sessions within a short time window

Detection Strategies

Inspect web server logs for POST or GET requests to sensitive endpoints where the Referer header does not match the application's own origin
Correlate session activity to flag actions that occur without prior legitimate page views in the same session
Deploy web application firewall (WAF) rules that require presence and validity of anti-CSRF tokens on POST endpoints

Monitoring Recommendations

Alert on authenticated requests missing an Origin or Referer header on sensitive routes
Track anomalous volumes of state-changing operations per user account
Retain HTTP request logs with full headers to enable retrospective CSRF investigations

How to Mitigate CVE-2025-7133

Immediate Actions Required

Restrict access to the application to trusted networks until anti-CSRF controls are added
Set application session cookies with SameSite=Strict or SameSite=Lax and the Secure flag
Require re-authentication for high-impact actions such as account changes or bulk bookings
Warn users against clicking untrusted links while logged into the application

Patch Information

No vendor patch has been published in the referenced advisories at the time of writing. Consult the CodeAstro project site and the VulDB CTI report for updates. Operators of forked or self-hosted deployments should add CSRF tokens to all state-changing forms and validate them server-side before release.

Workarounds

Implement per-session, per-form anti-CSRF tokens on all POST, PUT, and DELETE endpoints and validate them on the server
Enforce strict Origin and Referer header checks on state-changing requests
Configure SameSite=Strict cookies to prevent cross-origin session cookie transmission
Place the application behind a WAF configured with signatures for CSRF and cross-origin request abuse

bash

# Example Flask configuration hardening session cookies against CSRF
app.config.update(
    SESSION_COOKIE_SECURE=True,
    SESSION_COOKIE_HTTPONLY=True,
    SESSION_COOKIE_SAMESITE='Strict',
    WTF_CSRF_ENABLED=True,
    WTF_CSRF_TIME_LIMIT=3600,
)
