CVE-2026-47116: Use of Hard-coded Credentials in LTSecurity LTK3500SF
LTSecurity LTK3500SF devices have a critical vulnerability involving hard-coded credentials. The root and guest account passwords are stored as reversible hashes in the /etc/shadow file, allowing attackers to recover them using dictionary-based cracking tools. With these credentials, attackers can authenticate via Telnet or SSH and gain full root-level access to the operating system.
AI Analysis
Technical Summary
CVE-2026-47116 describes a hard-coded credentials vulnerability in LTSecurity LTK3500SF. The passwords for root and guest accounts are stored as reversible hashes in /etc/shadow, making them susceptible to recovery through dictionary attacks. Successful exploitation enables unauthorized authentication via Telnet or SSH, granting attackers full root privileges on the device's operating system.
Potential Impact
Attackers who recover the hard-coded credentials can authenticate remotely using Telnet or SSH, obtaining full root-level access. This compromises the confidentiality, integrity, and availability of the affected system, allowing complete control over the device.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict network access to Telnet and SSH services on affected devices and monitor for unauthorized access attempts.
