CVE-2025-15398: Uatech Badaso Auth Bypass Vulnerability

CVE-2025-15398 Overview

CVE-2025-15398 affects Uasoft Badaso through version 2.9.7. The flaw resides in the forgetPassword function within src/Controllers/BadasoAuthController.php, part of the Token Handler component. Manipulation of this function leads to a weak password recovery mechanism [CWE-640] that attackers can abuse over the network.

The exploit has been publicly disclosed. The vendor was contacted prior to disclosure but did not respond. Successful exploitation enables an attacker to compromise the password reset workflow against a target account, although the attack requires high complexity to execute.

Critical Impact
A remote, unauthenticated attacker can abuse the password recovery flow in Badaso to gain unauthorized access to victim accounts.

Affected Products

Uasoft Badaso versions up to and including 2.9.7
Component: Token Handler (BadasoAuthController.php)
Function: forgetPassword

Technical Details for CVE-2025-15398

Vulnerability Analysis

The vulnerability is a weak password recovery issue [CWE-640] in the Badaso authentication controller. Badaso is an open source content management system built on Laravel and Vue.js. The forgetPassword handler issues password reset tokens that an attacker can predict, replay, or otherwise manipulate to take control of arbitrary user accounts.

Because the affected logic sits in the password reset path, exploitation does not require valid credentials or user interaction. However, the attack is rated as high complexity, indicating that successful exploitation depends on specific conditions in the token generation or validation flow.

The EPSS probability for this CVE is 0.055%, reflecting limited observed exploitation activity. Public technical write-ups documenting the reset abuse chain are available through HXLab and VulDB entry 339207.

Root Cause

The root cause lies in how forgetPassword in src/Controllers/BadasoAuthController.php generates and validates password reset tokens. Insufficient entropy, missing binding between the token and the requesting session, or weak verification of the token allows an attacker to forge or guess a valid reset artifact and submit a new password for the victim account.

Attack Vector

The attack vector is network-based. An unauthenticated attacker triggers a password reset for a victim account, then leverages the weakness in the token handler to complete the reset and authenticate as the victim. Refer to the HXLab Password Reset Guide for the disclosed exploitation steps.

Detection Methods for CVE-2025-15398

Indicators of Compromise

Multiple password reset requests targeting the same account from one or more source IPs in a short window
Successful password reset confirmations not preceded by the user's interactive request
Authentications from new IP addresses or user agents immediately following a reset event

Detection Strategies

Inspect Badaso application logs for high-volume calls to the forgetPassword endpoint and corresponding token submission requests.
Correlate password reset events with subsequent login activity to surface accounts where reset and login originate from different clients.
Alert when reset tokens are submitted with timing or sequencing patterns inconsistent with normal user behavior.

Monitoring Recommendations

Forward Laravel and web server logs covering BadasoAuthController to a centralized SIEM for correlation.
Track per-account and per-IP rate metrics for password reset triggers and completions.
Monitor administrative accounts in Badaso installations with priority, since takeover of an admin user enables full CMS compromise.

How to Mitigate CVE-2025-15398

Immediate Actions Required

Restrict network exposure of Badaso administrative endpoints to trusted networks or VPN until a fix is available.
Force password resets and review session activity for any account showing anomalous reset events.
Enable multi-factor authentication on all Badaso accounts where the deployment supports it, to limit the value of a stolen password.

Patch Information

No vendor patch has been published. According to the disclosure, Uasoft did not respond to early notification. Track the VulDB entry #339207 for updates and apply any community or vendor fix as soon as it becomes available.

Workarounds

Disable or rate-limit the forgetPassword endpoint at the reverse proxy or web application firewall layer.
Require administrator-mediated password resets while the vulnerability remains unpatched.
Rotate any application secrets used in token generation and shorten reset token validity windows in configuration where supported.

bash

# Example nginx rate limit for the password reset endpoint
limit_req_zone $binary_remote_addr zone=badaso_reset:10m rate=5r/m;

location /api/v1/auth/forgetPassword {
    limit_req zone=badaso_reset burst=5 nodelay;
    proxy_pass http://badaso_backend;
