CVE-2025-7630: Wispotter Auth Bypass Vulnerability

CVE-2025-7630 Overview

CVE-2025-7630 is an authentication vulnerability affecting Doruk Communication and Automation Industry and Trade Inc. Wispotter software. The vulnerability involves improper restriction of excessive authentication attempts combined with improper authentication mechanisms, enabling attackers to perform password brute forcing attacks against the system.

Critical Impact

Attackers can exploit this vulnerability to perform brute force attacks against authentication mechanisms, potentially gaining unauthorized access to Wispotter systems through password guessing.

Affected Products

• Doruk Wispotter versions from 1.0 before v2025.10.08.1

Technical Details for CVE-2025-7630

Vulnerability Analysis

This vulnerability falls under CWE-287 (Improper Authentication), which encompasses a broad category of authentication-related weaknesses. The Wispotter application fails to implement adequate controls to limit the number of authentication attempts, making it susceptible to brute force attacks.

The network-accessible nature of this vulnerability means attackers can attempt authentication remotely without requiring any prior privileges or user interaction. While the immediate impact is limited to confidentiality concerns with potential unauthorized information disclosure, successful exploitation could lead to complete account compromise.

Root Cause

The root cause stems from two interrelated authentication weaknesses:

1. Improper Restriction of Excessive Authentication Attempts - The application lacks rate limiting, account lockout mechanisms, or CAPTCHA verification after multiple failed login attempts
2. Improper Authentication - Underlying authentication implementation weaknesses that make brute force attacks more effective

These deficiencies allow automated tools to submit unlimited authentication requests without triggering defensive countermeasures.

Attack Vector

The attack is conducted over the network without requiring authentication or user interaction. Attackers can leverage automated password guessing tools to enumerate valid credentials through repeated authentication attempts against the Wispotter login interface.

The attack flow typically involves:

1. Identifying the Wispotter authentication endpoint
2. Using wordlists or credential databases to attempt numerous password combinations
3. Exploiting the lack of rate limiting to accelerate attack speed
4. Successfully authenticating once valid credentials are discovered

Due to the absence of verified code examples, organizations should refer to the USOM Notification TR-26-0070 for additional technical details regarding this vulnerability.

Detection Methods for CVE-2025-7630

Indicators of Compromise

• Unusually high volume of failed authentication attempts from single IP addresses
• Rapid succession of login attempts against user accounts
• Authentication logs showing multiple credential combinations being tested
• Distributed authentication attempts across multiple accounts from suspicious IP ranges

Detection Strategies

• Implement authentication monitoring to detect abnormal login patterns and failed attempt thresholds
• Deploy web application firewalls (WAF) configured to detect and block brute force attack signatures
• Configure intrusion detection systems (IDS) with rules for authentication-based attacks
• Enable verbose logging on authentication endpoints to capture detailed request information

Monitoring Recommendations

• Set up alerts for failed authentication attempts exceeding defined thresholds (e.g., 5+ failures per minute)
• Monitor for geographic anomalies in authentication traffic
• Track authentication attempt velocity and implement baseline deviation alerts
• Review access logs regularly for patterns consistent with credential stuffing or brute force campaigns

How to Mitigate CVE-2025-7630

Immediate Actions Required

• Upgrade Doruk Wispotter to version v2025.10.08.1 or later immediately
• Implement additional network-level access controls to restrict authentication endpoint exposure
• Enable multi-factor authentication (MFA) if supported
• Review authentication logs for evidence of prior exploitation attempts

Patch Information

Doruk Communication and Automation Industry and Trade Inc. has addressed this vulnerability in Wispotter version v2025.10.08.1. Organizations should upgrade from any version between 1.0 and v2025.10.08.1 to the patched release. Refer to the USOM Notification TR-26-0070 for official vendor guidance.

Workarounds

• Implement IP-based rate limiting at the network or application level to restrict authentication attempts
• Deploy a reverse proxy with brute force protection capabilities in front of the Wispotter application
• Configure account lockout policies that temporarily disable accounts after repeated failed attempts
• Restrict access to authentication endpoints to trusted IP ranges or VPN connections only

# Example rate limiting configuration (generic web server)
# Consult your specific infrastructure documentation for implementation
# Limit authentication endpoint to 5 requests per minute per IP
# iptables -A INPUT -p tcp --dport 443 -m recent --name AUTH --update --seconds 60 --hitcount 5 -j DROP
