CVE-2025-9062: Envanty Auth Bypass Vulnerability

CVE-2025-9062 Overview

CVE-2025-9062 is an Authorization Bypass Through User-Controlled Key vulnerability (CWE-639) affecting MeCODE Informatics and Engineering Services Ltd. Envanty software. This vulnerability allows attackers to perform Parameter Injection attacks, potentially enabling unauthorized access to resources that should be restricted.

The vulnerability exists in Envanty versions prior to 1.0.6. According to the security disclosure, the vendor was contacted early about this issue but did not respond. The vulnerability was confirmed to be remediated through reporter information and independent testing.

Critical Impact

Attackers on the adjacent network with low privileges can exploit this vulnerability to achieve high-impact unauthorized access to confidential data and modify protected resources without proper authorization.

Affected Products

• MeCODE Informatics and Engineering Services Ltd. Envanty versions before 1.0.6

Technical Details for CVE-2025-9062

Vulnerability Analysis

This vulnerability falls under CWE-639 (Authorization Bypass Through User-Controlled Key), which occurs when an application uses user-supplied input as a key to access resources without properly validating that the user is authorized to access those resources. In Envanty, this manifests as a Parameter Injection weakness where an attacker can manipulate request parameters to access or modify data belonging to other users or resources they shouldn't have permission to interact with.

The adjacent network attack vector indicates that exploitation requires the attacker to be on the same network segment as the vulnerable system, which somewhat limits the attack surface compared to internet-facing vulnerabilities. However, low privileges are required for exploitation, meaning authenticated users with minimal access could potentially escalate their access significantly.

Root Cause

The root cause is improper authorization logic that relies on user-controlled input to determine access rights. When an application uses a key (such as user ID, account number, or resource identifier) directly from user input without verifying the requestor's authorization to access that particular resource, it creates an Insecure Direct Object Reference (IDOR) condition. The application fails to enforce server-side authorization checks before returning or modifying the requested data.

Attack Vector

The vulnerability is exploitable from an adjacent network position with low-complexity attack requirements. An authenticated attacker with minimal privileges can manipulate request parameters to reference resources belonging to other users. By modifying identifier values in API requests or form submissions, the attacker can bypass authorization controls to access confidential information or modify data they should not have access to.

The attack does not require user interaction, making it viable for automated exploitation once the attacker has network adjacency and basic authentication credentials.

Detection Methods for CVE-2025-9062

Indicators of Compromise

• Unusual access patterns showing users accessing resources outside their normal scope
• Audit logs indicating repeated requests with sequentially modified resource identifiers
• Access attempts to resources immediately after parameter manipulation in requests
• Multiple authorization failures followed by successful access to unrelated resources

Detection Strategies

• Monitor application logs for parameter tampering attempts, particularly on resource identifier fields
• Implement anomaly detection for users accessing resources outside their typical access patterns
• Deploy Web Application Firewall (WAF) rules to detect and block parameter injection attempts
• Review access control logs for cross-account or cross-resource access attempts

Monitoring Recommendations

• Enable detailed logging for all resource access operations in Envanty
• Configure SIEM alerts for sequential resource ID enumeration attempts
• Monitor for authenticated sessions accessing resources belonging to multiple different users
• Track and alert on authorization bypass attempts and unusual privilege usage patterns

How to Mitigate CVE-2025-9062

Immediate Actions Required

• Upgrade Envanty to version 1.0.6 or later immediately
• Audit access logs for any signs of exploitation prior to patching
• Review and strengthen authorization controls for sensitive resources
• Implement network segmentation to limit adjacent network access where possible

Patch Information

MeCODE Informatics and Engineering Services Ltd. has addressed this vulnerability in Envanty version 1.0.6. Organizations should upgrade to this version or later to remediate the vulnerability. For additional details on the security advisory, refer to the USOM Security Notification TR-26-0076.

Workarounds

• Implement additional server-side authorization checks to validate user permissions before resource access
• Deploy network access controls to restrict adjacent network connectivity to trusted systems only
• Enable comprehensive audit logging and monitor for suspicious access patterns
• Consider implementing rate limiting on resource access endpoints to slow enumeration attempts

If immediate patching is not possible, organizations should implement compensating controls such as enhanced monitoring, network isolation, and additional authentication requirements for sensitive operations until the upgrade can be completed.
