CVE-2025-0606 Overview
CVE-2025-0606 is an Authorization Bypass Through User-Controlled Key vulnerability [CWE-639] in Logo Software Inc.'s Logo Cloud product. The flaw allows authenticated attackers to perform forceful browsing and trigger resource leak exposure by manipulating user-controlled identifiers in requests. Logo Cloud versions prior to 0.67 are affected. The vulnerability is network-accessible and requires high privileges, with no user interaction needed. Successful exploitation can expose sensitive resources belonging to other tenants or users within the Logo Cloud environment.
Critical Impact
Authenticated attackers can bypass authorization checks by substituting identifiers in requests, gaining access to resources belonging to other users and causing resource leak exposure.
Affected Products
- Logo Software Inc. Logo Cloud versions before 0.67

Technical Details for CVE-2025-0606
Vulnerability Analysis
CVE-2025-0606 is categorized under [CWE-639]: Authorization Bypass Through User-Controlled Key, commonly referred to as Insecure Direct Object Reference (IDOR). Logo Cloud exposes resource identifiers in requests without validating that the authenticated user owns or has access to those resources. Attackers who already hold valid credentials can modify these identifiers to enumerate and retrieve resources belonging to other accounts. The result is forceful browsing of restricted endpoints and uncontrolled consumption or exposure of backend resources.
Root Cause
The root cause is missing server-side authorization enforcement on object identifiers that originate from the client. Logo Cloud trusts the user-supplied key, such as a numeric record ID or tenant reference, to determine which resource to return. Without a cross-check against the session principal, the application returns data outside the caller's authorization scope.
Attack Vector
Exploitation requires network access and valid authenticated credentials to the Logo Cloud application. An attacker iterates or substitutes identifier values in API or web requests to reach records they should not be able to view or modify. The flaw also enables resource leak exposure, where repeated unauthorized requests disclose backend state or exhaust tracked resources.
No verified public exploit code is available. See the USOM Alert TR-25-0318 and the Siber Güvenlik Notification TR-25-0318 for the official advisory.
Detection Methods for CVE-2025-0606
Indicators of Compromise
- Sequential or enumerated access patterns against Logo Cloud endpoints that reference numeric or GUID identifiers.
- Authenticated sessions requesting resources outside the user's normal tenant or account scope.
- Elevated response sizes or 200 OK responses on object IDs the account has never previously accessed.
Detection Strategies
- Correlate authenticated user IDs with the object identifiers they request and alert when the mapping deviates from historical baselines.
- Inspect web and API gateway logs for high-rate ID enumeration patterns targeting Logo Cloud resource endpoints.
- Flag HTTP responses that return cross-tenant data references within a single session.
Monitoring Recommendations
- Enable verbose request logging on Logo Cloud, including authenticated principal, requested resource ID, and response code.
- Forward application and gateway logs to a central analytics platform for behavioral correlation across users.
- Create alerts for authenticated accounts that request a statistically unusual breadth of object identifiers in a short window.
How to Mitigate CVE-2025-0606
Immediate Actions Required
- Upgrade Logo Cloud to version 0.67 or later as published by Logo Software Inc.
- Review authentication logs for high-privilege accounts and rotate credentials where suspicious enumeration is observed.
- Audit access logs for cross-account resource access during the exposure window prior to patching.
Patch Information
Logo Software Inc. addressed CVE-2025-0606 in Logo Cloud version 0.67. Administrators should confirm the running version and apply the vendor update. Refer to the USOM Alert TR-25-0318 for the coordinated advisory details.
Workarounds
- Restrict Logo Cloud administrative and high-privilege access to known IP ranges until the patch is applied.
- Enforce short session lifetimes and multi-factor authentication for all privileged Logo Cloud accounts.
- Place a reverse proxy or web application firewall rule in front of Logo Cloud to rate-limit identifier enumeration patterns.
