CVE-2025-0640

4.7 MEDIUM

📋 TL;DR

CVE-2025-0640 is an authorization bypass vulnerability in Akinsoft OctoCloud that allows attackers to access resources they shouldn't have permission to view by manipulating user-controlled keys. This affects OctoCloud versions from s1.09.02 through v1.11.01, potentially exposing sensitive data to unauthorized users.

💻 Affected Systems

Products:
  • Akinsoft OctoCloud
Versions: from s1.09.02 before v1.11.01
Operating Systems: Not OS-specific - affects OctoCloud application
Default Config Vulnerable: ⚠️ Yes
Notes: All deployments running affected versions are vulnerable regardless of configuration.

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete compromise of sensitive data including customer information, financial records, or proprietary business data through unauthorized access to all system resources.

🟠

Likely Case

Unauthorized access to specific resources or data that should be restricted, leading to data leakage and potential privacy violations.

🟢

If Mitigated

Limited exposure of non-critical resources with proper access controls and monitoring in place.

🌐 Internet-Facing: MEDIUM - While authentication is typically required, once authenticated users can potentially bypass authorization controls to access other users' resources.
🏢 Internal Only: MEDIUM - Internal users could exploit this to access resources beyond their intended permissions, though network segmentation provides some protection.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Requires authenticated access but then allows bypassing authorization controls through parameter manipulation.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: v1.11.01 or later

Vendor Advisory: https://www.usom.gov.tr/bildirim/tr-25-0203

Restart Required: No

Instructions:

1. Backup current configuration and data. 2. Download OctoCloud v1.11.01 or later from official vendor sources. 3. Apply the update following vendor documentation. 4. Verify the update completed successfully.

🔧 Temporary Workarounds

Implement strict input validation

all

Add server-side validation for all user-controlled keys and parameters to ensure they match authorized resources

Enhance access control logging

all

Implement detailed logging of all resource access attempts to detect potential authorization bypass attempts

🧯 If You Can't Patch

  • Implement network segmentation to isolate OctoCloud from sensitive systems
  • Deploy web application firewall (WAF) with rules to detect and block parameter manipulation attempts

🔍 How to Verify

Check if Vulnerable:

Check OctoCloud version via admin interface or configuration files. If version is between s1.09.02 and v1.11.01 (exclusive), system is vulnerable.

Check Version:

Check OctoCloud admin panel or configuration files for version information

Verify Fix Applied:

Confirm version is v1.11.01 or later and test authorization controls with various user roles to ensure proper access restrictions.

📡 Detection & Monitoring

Log Indicators:

  • Unusual access patterns to resources, multiple failed authorization attempts followed by successful access, access to resources by users not in authorized groups

Network Indicators:

  • Unusual parameter values in HTTP requests, repeated requests with modified resource identifiers

SIEM Query:

source="octocloud" AND (event_type="access_denied" OR event_type="unauthorized_access") | stats count by user, resource
