Summary
by MITRE • 09/30/2026
A vulnerability was found in AdithyaYelloju Restaurant-Management-System up to 7f0e7e84255e8fcfd488e83f8f91451bbbff6b9c. This issue affects the function mysqli_query of the file admin/delete1.php of the component Unauthenticated Action Script. Performing a manipulation of the argument ID results in sql injection. The attack can be initiated remotely. The exploit has been made public and could be used. Continious delivery with rolling releases is used by this product. Therefore, no version details of affected nor updated releases are 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 security flaw within its administrative interface that allows for remote code execution via database manipulation. Specifically, the vulnerability resides in the admin/delete1.php script, which handles unauthenticated actions related to data deletion operations. The core technical issue is an SQL injection weakness located within the mysqli_query function call. This function processes user-supplied input without adequate sanitization or parameterization, creating a direct pathway for attackers to inject malicious SQL commands into the backend database engine.
The vulnerability stems from improper handling of the ID argument passed during deletion requests. When this identifier is manipulated by an external actor, it bypasses expected validation checks and gets concatenated directly into SQL queries executed against the MySQL server. This lack of input validation means that any string provided in place of a valid numeric or alphanumeric ID can be interpreted as executable code rather than data. Consequently, attackers can craft payloads to extract sensitive information from other tables, modify existing records, delete critical system data, or potentially escalate privileges depending on the database user permissions assigned to the web application process.
From an operational perspective, this flaw poses a severe risk to the confidentiality and integrity of restaurant management data. Since the affected component is labeled as an unauthenticated action script, the attack does not require valid credentials for administrative access. This significantly lowers the barrier to entry for malicious actors, allowing anyone with network connectivity to exploit the vulnerability remotely. The impact includes potential exposure of customer personal information, financial records, inventory details, and employee data stored within the system's database. Furthermore, because continuous delivery with rolling releases is employed by this product, there are no specific version numbers available to identify affected or patched instances. This lack of clear versioning complicates vulnerability management efforts for organizations relying on this software, as they cannot easily determine if their deployment falls within the vulnerable range based solely on version strings.
The exploit code for this SQL injection has been made public, which increases the likelihood of automated scanning and exploitation by threat actors using widely available tools. Despite being informed early through an issue report, the project maintainers have not yet responded or provided a fix. This delay leaves users exposed to ongoing risks without official mitigation guidance from the vendor. In such scenarios, organizations must rely on defensive measures rather than waiting for upstream patches.
To mitigate this vulnerability in the absence of an official update, administrators should implement strict input validation and use prepared statements with parameterized queries instead of direct string concatenation when interacting with the database. Additionally, deploying a Web Application Firewall can help filter out malicious SQL patterns before they reach the application logic. Network-level controls such as restricting access to administrative endpoints like delete1.php via IP whitelisting or multi-factor authentication can also reduce the attack surface. Regular security audits and code reviews focusing on data handling practices are essential for preventing similar flaws in future development cycles. The vulnerability aligns with CWE-89, which describes Improper Neutralization of Special Elements used in an SQL Command, and maps to ATT&CK technique T1059, specifically command scripting or database query injection vectors depending on the specific payload executed by the attacker.
