Vulnerability from github – Published: 2025-12-02 00:37 – Updated: 2025-12-02 00:37Exposure of Password Hashes Leading to privilege escalation
Severity Rating: Medium
Vector: Privilege Escalation
CVE: XXX
CWE: 200 - Exposure of Sensitive Information
CVSS Score: 6.2
CVSS Vector: CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:L
Analysis
It was observed that if a users is given read access on the user account management section of the admin panel can view the password hashes of all users, including the admin user. This exposure can potentially lead to privilege escalation if an attacker can crack these password hashes.
An attacker with read access can: * View and potentially crack the password hashes. * Gain administrative access by cracking the admin password hash. * Escalate privileges and compromise the entire admin panel.
Proof of Concept
1) Give read access to user accounts to a random user as shown in the following figures:
2) Log in to the admin panel with an account that has read access to user accounts and navigate to the user account management section.
3) Go to the admin profile http://127.0.0.1/admin/accounts/users/admin; The password is not display. Try inspecting the page source code as shown in the following figures:
You can see that it match the hash that is in the admin.yaml file :
4) Crack the hash as shown in the following figure, the algorithm use here is bcrypt:
