CVE-2026-2669: Rongzhitong Auth Bypass Vulnerability

CVE-2026-2669 Overview

A vulnerability has been identified in Rongzhitong Visual Integrated Command and Dispatch Platform up to version 20260206. This security flaw impacts the User Handler component, specifically affecting the /dm/dispatch/user/delete endpoint. The vulnerability allows attackers to manipulate the ID argument to bypass access controls, enabling unauthorized user deletion operations. Remote exploitation is possible, and the exploit has been publicly disclosed.

Critical Impact

Unauthorized attackers can remotely delete user accounts through improper access control in the User Handler component, potentially disrupting system operations and compromising user management integrity.

Affected Products

• Rongzhitong Visual Integrated Command and Dispatch Platform up to version 20260206
• User Handler component (/dm/dispatch/user/delete endpoint)

Technical Details for CVE-2026-2669

Vulnerability Analysis

This vulnerability is classified as Improper Access Controls (CWE-266: Incorrect Privilege Assignment). The affected component fails to properly verify user authorization before processing deletion requests to the /dm/dispatch/user/delete endpoint. When a request is made to this endpoint with an ID parameter, the system does not adequately validate whether the requesting user has appropriate privileges to perform the deletion operation.

The flaw enables unauthenticated or low-privileged remote attackers to craft malicious requests targeting arbitrary user accounts for deletion. This represents a significant broken access control vulnerability that could be leveraged to disrupt operations, remove administrator accounts, or cause denial of service conditions within the platform.

The vendor was contacted regarding this disclosure but did not respond, leaving users without an official patch or guidance.

Root Cause

The root cause of this vulnerability stems from CWE-266 (Incorrect Privilege Assignment), where the User Handler component fails to implement proper authorization checks before executing user deletion operations. The /dm/dispatch/user/delete endpoint accepts an ID argument without validating that the requesting entity has the necessary privileges to delete the specified user account.

Attack Vector

The attack can be executed remotely over the network without requiring user interaction. An attacker can craft HTTP requests to the vulnerable endpoint /dm/dispatch/user/delete while manipulating the ID parameter to target specific user accounts. Since the system lacks proper access control validation, these requests are processed regardless of the attacker's authorization level.

The vulnerability mechanism involves sending crafted requests to the User Handler endpoint. Technical details and proof-of-concept information have been documented in the GitHub PoC Repository. Additional vulnerability intelligence is available through VulDB #346466.

Detection Methods for CVE-2026-2669

Indicators of Compromise

• Unusual or unauthorized requests to /dm/dispatch/user/delete endpoint from unexpected source IPs
• Unexpected user account deletions in system audit logs
• Multiple rapid deletion requests targeting different user IDs
• Access attempts to the User Handler component from unauthenticated sessions

Detection Strategies

• Implement web application firewall (WAF) rules to monitor and alert on requests to /dm/dispatch/user/delete
• Configure intrusion detection systems (IDS) to flag suspicious patterns involving the User Handler endpoint
• Deploy endpoint detection and response (EDR) solutions to monitor for exploitation attempts
• Review access logs for requests containing manipulated ID parameters from unauthorized sources

Monitoring Recommendations

• Enable detailed logging for all authentication and authorization events within the platform
• Set up real-time alerting for user account modifications and deletions
• Implement anomaly detection for unusual patterns in User Handler component access
• Monitor network traffic for reconnaissance activity targeting the dispatch platform endpoints

How to Mitigate CVE-2026-2669

Immediate Actions Required

• Restrict network access to the Rongzhitong Visual Integrated Command and Dispatch Platform to trusted IP ranges only
• Implement additional authentication and authorization layers at the network or application perimeter
• Deploy web application firewall rules to block unauthorized access to /dm/dispatch/user/delete
• Review and audit all user accounts for potential unauthorized modifications
• Consider taking the affected endpoint offline until proper access controls can be implemented

Patch Information

No official patch is currently available from the vendor. The vendor was contacted early about this disclosure but did not respond in any way. Organizations should implement compensating controls and monitor for vendor updates through official channels.

For additional technical details, refer to the VulDB CTI entry and the VulDB submission.

Workarounds

• Implement network segmentation to isolate the affected platform from untrusted networks
• Add custom authentication middleware or reverse proxy rules to enforce authorization before requests reach the vulnerable endpoint
• Disable or remove the /dm/dispatch/user/delete endpoint if the functionality is not critical
• Deploy rate limiting on the User Handler component to slow potential exploitation attempts
• Implement IP allowlisting to restrict access to administrative functions

# Example: Block access to vulnerable endpoint using iptables (adjust IP ranges as needed)
# Allow only trusted management network
iptables -A INPUT -p tcp --dport 80 -s 10.0.0.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -s 10.0.0.0/24 -j ACCEPT
# Drop all other traffic to the platform
iptables -A INPUT -p tcp --dport 80 -j DROP
iptables -A INPUT -p tcp --dport 443 -j DROP
