This repository details an IDOR vulnerability in AbsysNet 2.3.1, which allows a remote attacker to brute-force session IDs via the /cgi-bin/ocap/ endpoint. Successful exploitation can compromise active user sessions, exposing authentication tokens in HTML. The attack is limited to active sessions and is terminated if the user logs out.
This tool is designed to help identify and exploit whether an application is vulnerable to this specific CVE-2024-11318. It is intended for use by cybersecurity professionals, researchers, and penetration testers to assess security in environments where they have explicit authorization.
If the vulnerability is confirmed, exploitation should only occur if you have proper authorization from the application or system owner.
Unauthorized use of this tool against systems or networks you do not own or have explicit permission to test is illegal and unethical. The author takes no responsibility for misuse or damage caused by this tool.
By using this tool, you agree to comply with all relevant laws and ethical standards. Always ensure you have explicit permission before conducting tests or exploiting vulnerabilities.
This vulnerability affects AbsysNet version 2.3.1 and allows a remote attacker to compromise an active user's session. The attack involves exploiting an IDOR (Insecure Direct Object Reference) vulnerability in the /cgi-bin/ocap/ endpoint, where the session identifier is susceptible to brute-forcing.
Upon successfully matching a session ID associated with an authenticated user, the authentication token is exposed in the HTML code. However, the attack is limited to active sessions, and if the affected user logs out, the attacker’s access is immediately terminated, restricting the persistence of the compromise.
With this vulerability is only posible to hijack user sessions that are currenltly logged in and if the current user loggeds off the attacker loses the conection.
