CVE-2025-7015: QR Menu Session Fixation Vulnerability

CVE-2025-7015 Overview

A Session Fixation vulnerability has been identified in Akın Software Computer Import Export Industry and Trade Ltd. QR Menu application. This vulnerability allows attackers to perform session fixation attacks, potentially enabling unauthorized access to user sessions. The flaw affects QR Menu versions prior to s1.05.12.

Critical Impact

Attackers can exploit this session fixation vulnerability to hijack user sessions, potentially gaining unauthorized access to sensitive user data and functionality within the QR Menu application.

Affected Products

• Akın Software QR Menu versions before s1.05.12

Technical Details for CVE-2025-7015

Vulnerability Analysis

This vulnerability is classified as Session Fixation (CWE-384), a type of authentication and authorization flaw that occurs when an application does not properly regenerate session identifiers after authentication. In the context of the QR Menu application, the system fails to invalidate or regenerate session tokens when users authenticate, allowing an attacker to set or predict a session identifier that will later be associated with a victim's authenticated session.

The attack requires network access and some level of authenticated privileges within the system. User interaction is required for successful exploitation, as the victim must be tricked into using a session identifier controlled by the attacker. The primary impact is on confidentiality, where successful exploitation could expose sensitive user information.

Root Cause

The root cause of this vulnerability lies in improper session management within the QR Menu application. The application fails to implement secure session handling practices, specifically:

1. Session identifiers are not regenerated upon successful user authentication
2. Pre-authentication session tokens remain valid after login
3. The application accepts externally supplied session identifiers without validation

This allows attackers to establish a session, obtain its identifier, and then trick a victim into authenticating with that same session, effectively hijacking the authenticated session.

Attack Vector

The attack follows a typical session fixation pattern:

1. The attacker initiates a session with the QR Menu application and obtains a valid session identifier
2. The attacker crafts a malicious link or delivery mechanism containing this session identifier
3. The victim is tricked into accessing the application using the attacker's session identifier
4. The victim authenticates, but the session identifier remains the same
5. The attacker now has access to the victim's authenticated session, gaining access to their data

The vulnerability is exploitable over the network, though it requires user interaction (the victim must click a malicious link or be otherwise directed to use the attacker's session). The attacker needs low-level privileges initially to establish the session that will be fixed.

Detection Methods for CVE-2025-7015

Indicators of Compromise

• Multiple authentication events associated with a single session identifier from different IP addresses or user agents
• Session identifiers in URL parameters being used during authentication flows
• Unusual patterns of session reuse across different users or geographic locations

Detection Strategies

• Monitor authentication logs for sessions that do not generate new session identifiers upon successful login
• Implement logging to track session identifier changes (or lack thereof) during authentication events
• Alert on sessions that show activity from multiple distinct IP addresses or dramatically different user agents

Monitoring Recommendations

• Enable detailed session management logging in the QR Menu application
• Implement real-time monitoring for session anomalies in authentication workflows
• Review access logs regularly for signs of session fixation attempts

How to Mitigate CVE-2025-7015

Immediate Actions Required

• Upgrade Akın Software QR Menu to version s1.05.12 or later immediately
• Review active sessions and invalidate any suspicious or long-lived sessions
• Implement additional session validation controls if immediate patching is not possible
• Educate users about the risks of clicking untrusted links

Patch Information

Akın Software has addressed this vulnerability in QR Menu version s1.05.12. Organizations should update to this version or later to remediate the session fixation vulnerability. For additional details, refer to the USOM Security Notification TR-26-0006.

Workarounds

• Implement session regeneration at the web server or proxy level if application patching is delayed
• Configure shorter session timeout values to limit the window of opportunity for attackers
• Deploy additional authentication factors (MFA) to reduce the impact of session compromise
• Consider implementing IP-binding for sessions where feasible to detect session sharing across different networks
