CVE-2024-42464
📋 TL;DR
This vulnerability allows attackers to bypass authorization controls in upKeeper Manager by manipulating user-controlled keys in REST API requests, potentially leading to unauthorized access to sensitive data. It affects all users of upKeeper Manager versions through 5.1.9, particularly those with internet-facing deployments or insufficient access controls.
💻 Affected Systems
- upKeeper Manager
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could exfiltrate sensitive user information, such as credentials or personal data, leading to data breaches, compliance violations, and reputational damage.
Likely Case
Unauthorized users gain access to restricted data, such as user details or system information, compromising confidentiality and potentially enabling further attacks.
If Mitigated
With proper network segmentation and access controls, impact is limited to internal data exposure, reducing the risk of external exploitation.
🎯 Exploit Status
Exploitation likely requires some knowledge of the API structure but is based on a common authorization bypass pattern (CWE-639).
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Version after 5.1.9 (specific version not stated in CVE, check vendor advisory)
Vendor Advisory: https://support.upkeeper.se/hc/en-us/articles/15432275702044-CVE-2024-42464-Leak-of-user-Information
Restart Required: Yes
Instructions:
1. Check current version using vendor-provided method. 2. Download and apply the latest patch from upKeeper Solutions. 3. Restart the upKeeper Manager service to apply changes. 4. Verify the fix by testing authorization controls.
🔧 Temporary Workarounds
Restrict API Access
allLimit network access to the upKeeper Manager REST API to trusted IPs only, reducing exposure to unauthorized requests.
Use firewall rules (e.g., iptables on Linux or Windows Firewall) to block external access to the API port.
Enforce Strong Authentication
allImplement additional authentication layers, such as multi-factor authentication, to mitigate authorization bypass attempts.
Configure authentication settings in upKeeper Manager or integrate with external identity providers.
🧯 If You Can't Patch
- Isolate the upKeeper Manager instance on a segmented network to limit potential attack surface.
- Monitor and audit API logs for unusual access patterns or unauthorized data requests to detect exploitation attempts.
🔍 How to Verify
Check if Vulnerable:
Check the upKeeper Manager version; if it is 5.1.9 or earlier, it is vulnerable. Use the vendor's version check tool or administrative interface.Check Version:
Consult upKeeper Manager documentation or use a command like 'upkeeper-manager --version' if available, or check via the web interface.Verify Fix Applied:
After patching, confirm the version is above 5.1.9 and test API endpoints to ensure authorization controls are enforced properly.📡 Detection & Monitoring
Log Indicators:
- Unusual API requests with manipulated keys, access to sensitive endpoints from unauthorized users, or failed authorization logs.
Network Indicators:
- Abnormal traffic patterns to REST API endpoints, especially from untrusted sources.
