CVE-2026-1196: MineAdmin Information Disclosure Flaw

CVE-2026-1196 Overview

A security vulnerability has been detected in MineAdmin 1.x/2.x that allows information disclosure through improper handling of the ID argument in the /system/getFileInfoById endpoint. This vulnerability enables remote attackers to potentially access sensitive file information by manipulating request parameters sent to the affected function.

Critical Impact

Remote attackers can exploit this information disclosure vulnerability to gain unauthorized access to file metadata and potentially sensitive system information, though the attack requires high complexity and authenticated access.

Affected Products

• MineAdmin 1.x
• MineAdmin 2.x

Technical Details for CVE-2026-1196

Vulnerability Analysis

This vulnerability is classified as CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor). The flaw exists in an unknown function within the /system/getFileInfoById file of MineAdmin, where improper handling of the ID argument allows attackers to extract information that should not be accessible to them. While the attack is remotely exploitable, it requires authentication (low privileges) and involves high complexity, making successful exploitation difficult but not impossible for a determined attacker.

The exploit has been publicly disclosed, increasing the risk of active exploitation attempts. The vendor was contacted about this disclosure but did not respond, leaving users without official guidance or patches.

Root Cause

The root cause of this vulnerability stems from insufficient input validation and access control on the /system/getFileInfoById endpoint. The application fails to properly verify that the requesting user has appropriate permissions to access the file information associated with the provided ID parameter. This allows authenticated users to potentially enumerate and access file metadata for resources they should not have visibility into.

Attack Vector

The attack is conducted remotely over the network. An authenticated attacker can manipulate the ID parameter in requests to the /system/getFileInfoById endpoint to retrieve information about files they are not authorized to access. While the attack requires authentication and high complexity due to the conditions needed for exploitation, the publicly available exploit code lowers the barrier for technically capable attackers.

The vulnerability mechanism involves improper validation of the ID argument in the /system/getFileInfoById endpoint. Technical details and proof-of-concept information can be found in the GitHub Issue on MineAdmin Vulnerability.

Detection Methods for CVE-2026-1196

Indicators of Compromise

• Unusual or repeated requests to /system/getFileInfoById with varying or sequential ID parameter values
• Authenticated users accessing file information outside their normal scope of access
• Anomalous patterns in API access logs showing enumeration behavior against file endpoints
• Failed and successful requests to the affected endpoint from unexpected user accounts

Detection Strategies

• Monitor web application logs for suspicious access patterns to /system/getFileInfoById
• Implement rate limiting detection for repeated requests with different ID parameters
• Review authentication logs for accounts making unusual file information queries
• Deploy web application firewall rules to detect parameter tampering on sensitive endpoints

Monitoring Recommendations

• Enable detailed logging for all requests to the /system/getFileInfoById endpoint
• Configure alerts for sequential or bulk parameter enumeration attempts
• Monitor for unauthorized file information access by correlating user permissions with accessed resources
• Regularly audit access logs for patterns consistent with information disclosure exploitation

How to Mitigate CVE-2026-1196

Immediate Actions Required

• Restrict access to the /system/getFileInfoById endpoint through network-level controls or firewall rules
• Implement strict authentication and authorization checks for all file information retrieval functions
• Consider disabling the affected endpoint if not critical to operations until a patch is available
• Review and audit user permissions to ensure principle of least privilege

Patch Information

No official patch is currently available from the vendor. The vendor was contacted about this disclosure but did not respond. Organizations should monitor the VulDB entry and official MineAdmin channels for any future security updates. In the absence of vendor patches, organizations should implement the workarounds listed below to reduce risk exposure.

Workarounds

• Apply web application firewall rules to filter and validate ID parameter inputs
• Implement additional server-side authorization checks before returning file information
• Restrict access to the MineAdmin administrative interface to trusted networks only
• Consider deploying a reverse proxy with enhanced logging and access controls for the affected endpoint

# Example: Restrict access to affected endpoint via nginx
location /system/getFileInfoById {
    # Allow only from trusted internal networks
    allow 10.0.0.0/8;
    allow 192.168.0.0/16;
    deny all;
    
    # Add rate limiting
    limit_req zone=api_limit burst=5 nodelay;
}
