CVE-2026-105170 in food-waste-management-system
Summary
by MITRE • 10/05/2026
A weakness has been identified in kishor-23 food-waste-management-system 411989e3ecb82895e53dca7865f72145f03d7d93/b3a70b2c492dc9904de5be1ad9389bd79b87f82c. Affected is an unknown function of the file admin/signup.php of the component Admin Signup. This manipulation of the argument sign causes missing authentication. 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 identified vulnerability resides within the kishor-23 food-waste-management-system, specifically affecting the admin signup functionality implemented in the file admin/signup.php. This security flaw is classified as a missing authentication weakness, which fundamentally undermines the integrity of access control mechanisms for administrative accounts. The core technical issue stems from improper validation or handling of the sign argument during the account creation process. Instead of enforcing strict identity verification and credential management protocols before granting elevated privileges, the system allows an attacker to manipulate this input parameter to bypass standard registration checks. This misconfiguration effectively permits unauthorized entities to create administrator-level accounts without providing valid credentials or undergoing proper authentication procedures. Such a flaw is critical because it grants attackers immediate administrative access to the application backend, potentially leading to complete compromise of the system's confidentiality, integrity, and availability.
From an operational perspective, this vulnerability poses severe risks due to its remote exploitability. Attackers can initiate exploitation over a network connection without requiring prior authentication or physical proximity to the target infrastructure. The existence of public exploits significantly lowers the barrier for entry, enabling less sophisticated threat actors to leverage known techniques against vulnerable instances. Given that the project utilizes continuous delivery with rolling releases, determining specific affected versions is challenging as updates are deployed incrementally rather than through discrete version numbers. This dynamic release model complicates vulnerability management efforts for administrators who rely on static version checks to identify patch status. Consequently, organizations running this software must assume all recent builds may be vulnerable until explicit confirmation of a fix is provided by the vendor or community maintainers.
The lack of response from the project team since the initial issue report exacerbates the risk landscape. Without an official patch or workaround documented by the developers, defenders are left to implement compensating controls independently. This situation highlights common challenges in open-source projects where maintenance resources may be limited or communication channels inactive during critical security events. The absence of vendor guidance means that mitigation strategies must rely on general best practices for securing web applications and managing administrative interfaces rather than specific remediation steps provided by the author.
To mitigate this vulnerability, immediate defensive measures should focus on network-level restrictions and input validation enhancements. Administrators should restrict access to the admin signup endpoint using firewall rules or reverse proxy configurations that limit connections to trusted IP addresses only. Implementing Web Application Firewall (WAF) signatures can help detect and block malicious payloads targeting the sign parameter before they reach the application logic. Additionally, enforcing multi-factor authentication on all administrative accounts adds a critical layer of defense even if an attacker successfully creates an account through this flaw. Code-level remediation requires reviewing the signup.php script to ensure that user registration processes strictly validate inputs against expected formats and enforce unique credential requirements without allowing bypasses via parameter manipulation.
This vulnerability aligns with Common Weakness Enumeration (CWE) ID 287, which describes Improper Authentication, specifically relating to missing authentication for critical functionality. It also maps to MITRE ATT&CK technique T1078, Valid Accounts, as the attacker gains legitimate administrative credentials through exploitation rather than brute force or credential theft. By addressing these weaknesses through both technical controls and procedural updates, organizations can reduce their exposure to unauthorized access and potential data breaches associated with this food waste management system.
