CVE-2024-27605
📋 TL;DR
Alldata V0.4.6 has insecure permissions that allow low-privileged users (including test accounts) to query information about all users in the system. This affects any system running Alldata V0.4.6 with default or misconfigured permissions. The vulnerability enables unauthorized information disclosure about user accounts.
💻 Affected Systems
- Alldata
📦 What is this software?
Alldata by Alldata
⚠️ Risk & Real-World Impact
Worst Case
Attackers could enumerate all user accounts, gather usernames, email addresses, and potentially other sensitive user metadata, leading to targeted attacks, credential stuffing, or social engineering campaigns.
Likely Case
Unauthorized users accessing user lists and account information, potentially enabling reconnaissance for further attacks or violating privacy regulations.
If Mitigated
Limited to authorized users only accessing their own information, with proper access controls preventing enumeration of other users.
🎯 Exploit Status
Exploitation requires authenticated access but with low-privileged credentials. The GitHub gist demonstrates the vulnerability.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None provided in references
Restart Required: No
Instructions:
1. Check for updated versions beyond V0.4.6 from the vendor. 2. If available, upgrade to the patched version. 3. Verify permissions are properly configured after update.
🔧 Temporary Workarounds
Restrict User Query Permissions
allModify application permissions to prevent low-privileged users from querying information about other users.
# Configuration changes depend on Alldata's permission system. Review and modify user role permissions to restrict 'user query' or 'user enumeration' capabilities.
Remove or Disable Test Accounts
allEliminate test user accounts or restrict their permissions to prevent exploitation.
# Remove test users from the system or modify their permissions to prevent user enumeration queries.
🧯 If You Can't Patch
- Implement network segmentation to isolate Alldata systems from untrusted networks.
- Monitor and alert on unusual user enumeration activities in application logs.
🔍 How to Verify
Check if Vulnerable:
Authenticate as a low-privileged user (like 'test') and attempt to query user information through the application's user management interface or API endpoints.Check Version:
# Check Alldata version through application interface or configuration files. Exact command depends on deployment method.Verify Fix Applied:
After applying workarounds, attempt the same query with low-privileged accounts and verify access is denied or restricted to authorized information only.📡 Detection & Monitoring
Log Indicators:
- Multiple user query requests from low-privileged accounts
- Unusual patterns of user enumeration activity
Network Indicators:
- HTTP requests to user enumeration endpoints from unauthorized sources
SIEM Query:
source="alldata_logs" AND (event="user_query" OR endpoint="/api/users") AND user_role="low_privilege" | stats count by src_ip
