Missing Authentication in Admin Signup Parameter Handling

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.

Casky was already ahead

This CVE exploits attack patterns that Casky's 283matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

CVE-2026-105170 represents a critical authentication bypass vulnerability in the kishor-23 food-waste-management-system's admin signup functionality. By manipulating the 'sign' argument in admin/signup.php, attackers can bypass authentication controls entirely, gaining unauthorized administrative access without valid credentials. This vulnerability carries a CVSS score of 7.3 (high) and exploits weaknesses in both authentication mechanisms (CWE-287) and missing access controls (CWE-306). The attack is remotely exploitable with no user interaction required, making it particularly dangerous for organizations relying on this system. With public exploit code already available, threat actors have lowered the technical barrier for exploitation, creating immediate risk for any deployed instances.

Casky's 754 mapped security skills detect the attack patterns underlying this CVE through Claude AI's extended reasoning capabilities against MITRE ATT&CK techniques TA0004 (Privilege Escalation) and TA0006 (Credential Access). Practitioners using Casky would identify 283 matching skills flagging suspicious patterns including: unauthenticated requests to admin endpoints, parameter tampering on signup functions, and direct administrative access without credential validation. The platform's detection would surface anomalous auth flow behaviors—such as signup requests bypassing normal validation logic or admin privileges granted via URL manipulation—mapping these indicators to both initial access and privilege escalation techniques. This enables security teams to spot exploitation attempts in real-time and correlate them with known post-compromise behaviors, significantly reducing dwell time between attack initiation and detection.
