Summary
by MITRE • 10/13/2026
A vulnerability has been found in AdithyaYelloju Restaurant-Management-System up to 7f0e7e84255e8fcfd488e83f8f91451bbbff6b9c. This vulnerability affects unknown code of the file User/login.php of the component Login Form. Such manipulation of the argument email/passwd leads to improper authentication. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. This product takes the approach of rolling releases to provide continious delivery. Therefore, version details for affected and updated releases are not available. The project was informed of the problem early through an issue report but has not responded yet.

Analysis

The AdithyaYelloju Restaurant-Management-System contains a critical authentication bypass vulnerability within its login functionality, specifically located in the User/login.php file. This flaw stems from improper handling of user-supplied input for the email and password arguments during the authentication process. The root cause is identified as CWE-287, which denotes Improper Authentication, where the system fails to correctly verify the identity of a user before granting access. In this specific instance, the manipulation of these form fields allows an attacker to bypass standard credential validation mechanisms entirely. This type of vulnerability typically arises from weak logic in backend verification routines, such as SQL injection-based authentication bypasses or flawed conditional checks that allow empty strings or specially crafted payloads to satisfy login conditions without valid credentials.
The operational impact of this vulnerability is severe, as it enables remote attackers to gain unauthorized access to the application's administrative or user interfaces without possessing legitimate account details. Since the system manages restaurant operations, compromising these accounts could lead to significant data breaches involving customer personal information, payment records, and internal business metrics. The ability to launch attacks remotely means that threat actors do not need physical proximity or prior network access, significantly lowering the barrier for exploitation. This aligns with MITRE ATT&CK technique T1078, Valid Accounts, where adversaries use legitimate credentials obtained through bypass techniques to maintain persistence and move laterally within the target environment. The lack of proper session management following this bypass further exacerbates the risk, allowing persistent unauthorized access until sessions are manually terminated or expired by flawed server-side logic.
The exploit for this vulnerability has been publicly disclosed, which increases the likelihood of automated scanning tools and opportunistic attackers targeting instances of this software currently in use. Because the project utilizes a rolling release model to provide continuous delivery, specific version numbers affected by this flaw cannot be definitively isolated using traditional patch-based mitigation strategies. This dynamic update structure complicates vulnerability management for administrators who rely on static version checks to determine remediation status. The fact that the project maintainers have not yet responded to early issue reports suggests a potential gap in security maintenance practices, leaving deployed systems exposed until an official fix is released and propagated through their continuous delivery pipeline.
To mitigate this risk immediately, organizations running affected versions should implement compensating controls at the network or application layer if possible. Deploying Web Application Firewalls with rulesets designed to detect common authentication bypass patterns can help block exploitation attempts in real-time. Additionally, enforcing multi-factor authentication adds a secondary verification step that may remain secure even if the primary password check is compromised. Administrators should also monitor login logs for anomalous activity, such as multiple failed attempts followed by successful logins from unusual IP addresses or user agents. Until an official patch is available and verified against the rolling release stream, restricting public access to the login endpoint via IP whitelisting or VPN requirements can significantly reduce the attack surface. Regular audits of authentication logic in custom-built systems are essential to prevent such improper authentication flaws from persisting in production environments.
