Understanding CVE-2025-9902 Vulnerability

Cybersecurity has become a top priority in today’s rapidly evolving digital world. Recently, the vulnerability CVE-2025-9902, linked to the software QRMenu developed by AKIN Software, has drawn significant attention from security experts. Classified as a critical flaw, this vulnerability exploits an authorization bypass through a user-controlled key. Let’s break down this issue, its implications, and explore how to address it effectively.

What is CVE-2025-9902?

CVE-2025-9902 is a security flaw identified within QRMenu, a product under AKIN Software Computer Import Export Industry and Trade Co. Ltd. This vulnerability impacts versions of QRMenu from 1.05.12 to earlier releases prior to September 5, 2025. The issue arises due to improper handling of user-controlled keys, which can result in privilege abuse.

Why is This Vulnerability Critical?

With a CVSS score of 7.5, this vulnerability is deemed highly critical. It allows exploitation via a remote network vector, requiring no prior user interaction or privileged access. Essentially, malicious actors could leverage this flaw to access protected and sensitive areas within the QRMenu software without proper authentication.

Potential Consequences

Exploitation of this vulnerability could lead to:

• Unauthorized access to sensitive data.
• Malicious alterations of internal records.
• Exfiltration of critical information.

This poses a significant danger to organizations relying on QRMenu as a point-of-sale (POS) system, order management platform, or remote management interface.

Who is Most at Risk?

Organizations that expose their QRMenu software directly to the internet or operate networks with minimal security protocols are the most vulnerable. Additionally, management interfaces and connected terminals, such as kiosks, may further exacerbate the risks of exploitation.

How to Detect Potential Exploitation

To identify attacks exploiting this vulnerability, consider the following:

• Monitor logs for unauthorized access attempts to restricted APIs by unauthenticated users.
• Trace unusual access patterns involving elevated privileges.
• Set up alerts for actions that bypass normal authentication protocols.

Mitigation Strategies

To reduce the exposure to this vulnerability, implement these measures:

• Apply the patches provided by the vendor to update your software to the fixed version.
• Incorporate server-side validation of user-controlled keys to prevent manipulation.
• Restrict access to QRMenu endpoints using firewall rules or VPNs.
• Enhance privilege monitoring and apply the principle of least privilege.

AKIN Software has released an update to address this concern as of September 5, 2025. If you’re currently using QRMenu, ensure you install this update immediately to safeguard your systems.
