Authorization Bypass in Student Management System Admin Servlet

A weakness has been identified in Soarkey StudentManagement and 学生信息管理系统 up to e08f7f1d5015af407aa4cca0ada3dea189b4937e. This impacts the function AdminDao.doGet of the file code/src/service/AdminDao.java of the component Administrative Servlet. Executing a manipulation of the argument action can lead to authorization bypass. It is possible to launch the attack remotely. The exploit has been made available to the public and could be used for attacks. 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-2026-82621 represents a critical authorization bypass vulnerability in Soarkey StudentManagement and related student information management systems. By manipulating the 'action' argument in the AdminDao.doGet function within the Administrative Servlet component, attackers can circumvent access controls and gain unauthorized administrative privileges. This vulnerability affects educational institutions and organizations using vulnerable versions up to e08f7f1d5015af407aa4cca0ada3dea189b4937e, exposing sensitive student data and administrative functions to remote exploitation. The public availability of exploit code significantly increases the risk of widespread attacks against student record systems.

Casky's 283 mapped security skills detect the attack patterns underlying this vulnerability through Claude AI's extended reasoning capabilities across MITRE ATT&CK tactics TA0004 (Privilege Escalation) and TA0006 (Credential Access). Practitioners using Casky would identify suspicious findings including: improper servlet parameter validation (CWE-285 pattern recognition), parameter tampering attempts targeting 'action' fields in administrative endpoints, unauthorized elevation of privileges without proper authentication checks, and lateral movement patterns following initial access. The platform's skill mapping would flag inadequate access control enforcement in Java service layers, helping security teams detect unauthorized AdminDao function calls, unusual privilege escalation sequences in application logs, and administrative function invocations from unexpected source IPs—providing defense-in-depth visibility against this authorization bypass technique.
