This vulnerability in TieLabs Jannah arises from improper validation or control of filenames used in PHP include or require statements. It allows an attacker to perform Local File Inclusion (LFI), which can lead to disclosure of sensitive files, code execution, or denial of service. The issue affects all versions before 7.5.1. The CVSS 3.1 vector indicates network attack vector, high attack complexity, no privileges required, no user interaction, unchanged scope, and high impact on confidentiality, integrity, and availability.

Successful exploitation could allow an unauthenticated attacker to include arbitrary local files on the web server, potentially exposing sensitive information, executing malicious code, or causing service disruption. The high CVSS score reflects the critical impact on confidentiality, integrity, and availability of the affected system.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix information is provided, users should monitor TieLabs advisories for updates. Until a fix is available, consider restricting access to vulnerable endpoints and applying web application firewall rules to detect and block suspicious include/require requests related to this vulnerability.
