CVE-2021-35965
📋 TL;DR
CVE-2021-35965 is a critical vulnerability in the Orca HCM digital learning platform where a weak, hard-coded default administrator password is embedded in plain text in the webpage source code. This allows remote attackers to gain administrator privileges without authentication, affecting all users of the vulnerable platform.
💻 Affected Systems
- Orca HCM digital learning platform
📦 What is this software?
Orca Hcm by Learningdigital
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain full administrative control over the platform, enabling data theft, system manipulation, or deployment of malware across the entire organization's learning infrastructure.
Likely Case
Unauthorized access leading to privilege escalation, data breaches, and potential disruption of learning services.
If Mitigated
Limited impact if the password is changed or the system is patched, but initial exposure may still allow brief unauthorized access.
🎯 Exploit Status
Exploitation involves inspecting webpage source code to find the hard-coded password, requiring minimal technical skill.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified in references; check vendor for updated versions.
Vendor Advisory: Not provided in references; consult Orca HCM vendor or security advisories.
Restart Required: No
Instructions:
1. Contact Orca HCM vendor for the latest patched version. 2. Update the platform to the patched version. 3. Change all administrator passwords to strong, unique ones. 4. Review and audit user accounts for unauthorized access.
🔧 Temporary Workarounds
Change Default Administrator Password
allImmediately change the default administrator password to a strong, unique password to prevent unauthorized access.
Use the platform's admin interface to update the password; no specific command provided.
Restrict Access to Admin Interfaces
linuxLimit network access to the admin interface using firewalls or access control lists to reduce exposure.
Configure firewall rules to allow only trusted IPs to access admin ports (e.g., using iptables on Linux: 'iptables -A INPUT -p tcp --dport [admin_port] -s [trusted_ip] -j ACCEPT' and 'iptables -A INPUT -p tcp --dport [admin_port] -j DROP').
🧯 If You Can't Patch
- Isolate the Orca HCM system from the internet and restrict internal access to minimize attack surface.
- Implement multi-factor authentication and regular password changes for all administrator accounts to add layers of security.
🔍 How to Verify
Check if Vulnerable:
Inspect the webpage source code (e.g., via browser developer tools) for hard-coded passwords; check if default passwords are still in use.Check Version:
Check the platform's admin interface or documentation for version details; no specific command provided.Verify Fix Applied:
Verify that the hard-coded password is removed from the source code and that new, strong passwords are set for all admin accounts.📡 Detection & Monitoring
Log Indicators:
- Unusual login attempts from unknown IPs, multiple failed login attempts, or successful admin logins at odd hours.
Network Indicators:
- Suspicious traffic to admin interfaces, especially from external sources.
SIEM Query:
Example: 'source="orca_hcm_logs" AND (event_type="login" AND result="success" AND user="admin")' to detect admin logins.
