CVE-2025-2420: 猫宁i Morning CSRF Vulnerability

CVE-2025-2420 Overview

A Cross-Site Request Forgery (CSRF) vulnerability has been identified in the Morning (猫宁i Morning) application up to commit bc782730c74ff080494f145cc363a0b4f43f7d3e. This vulnerability affects an unknown functionality within the application, allowing attackers to trick authenticated users into performing unintended actions. The attack can be launched remotely, and exploit details have been publicly disclosed.

Critical Impact

Attackers can exploit this CSRF vulnerability to perform unauthorized actions on behalf of authenticated users, potentially leading to data manipulation, unauthorized state changes, or privilege abuse within the Morning application.

Technical Details for CVE-2025-2420

Vulnerability Analysis

This vulnerability stems from insufficient CSRF protection mechanisms within the Morning application. Cross-Site Request Forgery occurs when web applications fail to properly validate that requests originate from legitimate, trusted sources. In this case, the affected functionality lacks proper anti-CSRF tokens or other request validation mechanisms, enabling attackers to craft malicious requests that execute in the context of an authenticated user's session.

The Morning application follows a rolling release model for continuous delivery, which means traditional version-based tracking is not available. The vulnerability was tracked to commit hash bc782730c74ff080494f145cc363a0b4f43f7d3e and earlier iterations of the codebase.

Root Cause

The root cause of CVE-2025-2420 is classified under CWE-352 (Cross-Site Request Forgery). This weakness occurs when the web application does not, or cannot, sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request. The application fails to implement proper anti-forgery mechanisms such as:

• Synchronizer token patterns (CSRF tokens)
• Same-site cookie attributes
• Origin header validation
• Custom request headers for state-changing operations

Attack Vector

The attack requires user interaction through a network-based vector. An attacker must craft a malicious web page, email, or other content that causes a victim's browser to submit a forged HTTP request to the vulnerable Morning application. When an authenticated user visits the attacker-controlled content, their browser automatically includes valid session credentials, allowing the forged request to execute with the victim's privileges.

The attack scenario typically involves:

1. Attacker identifies a state-changing endpoint lacking CSRF protection
2. Attacker crafts a malicious HTML page containing a forged request
3. Victim with an active session visits the malicious page
4. Victim's browser submits the forged request with valid session cookies
5. The Morning application processes the request as legitimate

Detection Methods for CVE-2025-2420

Indicators of Compromise

• Unexpected state changes or data modifications in the Morning application without corresponding user activity
• Web server logs showing state-changing requests with external or suspicious Referer headers
• Anomalous patterns of POST requests from authenticated sessions originating from external domains

Detection Strategies

• Monitor web application logs for requests to state-changing endpoints with mismatched or missing Origin/Referer headers
• Implement Content Security Policy (CSP) reporting to detect potential CSRF attack attempts
• Deploy web application firewall (WAF) rules to detect and block suspicious cross-origin request patterns
• Review application audit logs for bulk or automated operations that don't match normal user behavior

Monitoring Recommendations

• Enable detailed request logging including Origin and Referer headers for forensic analysis
• Configure alerts for unusual request patterns targeting sensitive endpoints
• Monitor for signs of session abuse such as rapid sequential requests or geographically impossible session usage
• Implement browser-based telemetry to detect client-side attack indicators

How to Mitigate CVE-2025-2420

Immediate Actions Required

• Update the Morning application to the latest rolling release that includes CSRF protection fixes
• Implement anti-CSRF tokens for all state-changing operations
• Configure SameSite cookie attributes to Strict or Lax for session cookies
• Review and audit all application endpoints for proper CSRF protection

Patch Information

The Morning application uses a rolling release model, meaning specific version numbers are not available. Users should pull the latest commit from the official repository to obtain the security fix. The vulnerability was identified at commit bc782730c74ff080494f145cc363a0b4f43f7d3e and earlier. For patch details and current status, refer to the Gitee Issue Report.

Workarounds

• Implement a web application firewall (WAF) with CSRF detection rules as a temporary protective measure
• Configure the SameSite attribute on session cookies to prevent cross-origin request inclusion
• Deploy browser-based security controls such as Content Security Policy headers
• Educate users to log out of the Morning application when not actively using it to reduce the attack window

# Configuration example - Apache httpd SameSite cookie enforcement
# Add to httpd.conf or .htaccess
Header always edit Set-Cookie ^(.*)$ "$1; SameSite=Strict"

# Nginx equivalent configuration
# Add to server block
proxy_cookie_path / "/; SameSite=Strict";
