CVE-2026-95868 in Restaurant-Management-System
Summary
by MITRE • 09/23/2026
A weakness has been identified in AdithyaYelloju Restaurant-Management-System up to 7f0e7e84255e8fcfd488e83f8f91451bbbff6b9c. Affected by this issue is the function mysqli_query of the file admin/display_menu.php of the component Search Form. This manipulation of the argument s1 causes sql injection. The attack can be initiated remotely. The exploit has been made available to the public and could be used for attacks. 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 SQL injection vulnerability within its administrative interface, specifically located in the search functionality implemented in the file admin/display_menu.php. This flaw stems from improper input validation and sanitization practices when handling user-supplied data passed to the mysqli_query function via the argument s1. The system fails to properly escape special characters or utilize parameterized queries before incorporating this input into SQL statements, allowing an attacker to manipulate the structure of database commands executed by the backend server. This type of weakness is classically categorized under CWE-89, which defines Improper Neutralization of Special Elements used in an SQL Command, commonly known as SQL Injection. The vulnerability exists because the application directly concatenates or interpolates user input into a query string without adequate safeguards against malicious syntax injection.
The operational impact of this vulnerability is severe due to its remote exploitability and the nature of the affected component. Since the search form is part of the administrative module, it likely requires authentication; however, if credentials are compromised through other means or if the system exposes admin endpoints publicly, an attacker can leverage this flaw to execute arbitrary SQL commands against the underlying database. This capability enables a range of malicious activities including unauthorized data exfiltration, modification of critical restaurant management records such as menu items and orders, deletion of data, and potentially gaining control over the server through stacked queries if the database configuration permits it. The presence of public exploit code significantly lowers the barrier to entry for attackers, increasing the likelihood of automated scanning and exploitation attempts against systems running this software version or earlier commits up to 7f0e7e84255e8fcfd488e83f8f91451bbbff6b9c.
From a threat intelligence perspective, this vulnerability aligns with the MITRE ATT&CK technique T1059, Command and Scripting Interpreter, specifically when SQL injection is used to execute commands or extract data that facilitates further lateral movement or persistence within an organization's network infrastructure. The continuous delivery model employed by the project complicates remediation efforts for end-users since rolling releases mean there are no discrete version numbers to track updates against. This lack of clear versioning makes it difficult for administrators to determine whether their deployment includes a fix, especially given that the project maintainers have not yet responded to early issue reports regarding this security flaw. Consequently, organizations relying on this system face prolonged exposure risk until an official patch is released and clearly documented.
Mitigation strategies must focus on immediate code-level remediation and defensive configuration changes since waiting for upstream fixes may leave systems vulnerable indefinitely. Developers should refactor the affected PHP code in admin/display_menu.php to use prepared statements with bound parameters via the mysqli extension, ensuring that user input from s1 is treated strictly as data rather than executable SQL syntax. Additionally implementing strict input validation using allowlists for expected character sets can provide an extra layer of defense against injection attempts. For system administrators unable to immediately patch the source code, deploying a Web Application Firewall with rules specifically targeting SQL injection patterns in search parameters can help block exploitation attempts at the network perimeter while monitoring logs for signs of successful attacks such as unusual database query volumes or error messages indicating syntax failures.
