Advisory: E-Detective Lawful Interception System multiple security vulnerabilities Date: 14/06/2015 CVE: unassigned Authors: Mustafa Al-Bassam (https://musalbas.com) slipstream/RoL (https://twitter.com/TheWack0lian) Software: Decision Group E-Detective Lawful Interception System Vendor URL: http://www.edecision4u.com/ Software description: "E-Detective is a real-time Internet interception, monitoring and forensics system that captures, decodes, and reconstructs various types of Internet traffic. It is commonly used for organization Internet behavioral monitoring, auditing, record keeping, forensics analysis, and investigation, as well as, legal and lawful interception for lawful enforcement agencies such as Police Intelligence, Military Intelligence, Cyber Security Departments, National Security Agencies, Criminal Investigation Agencies, Counter Terrorism Agencies etc." Vulnerabilities: 1) Unauthenticated Local File Disclosure Proof-of-concept: https://github.com/musalbas/edetective-poc/blob/master/pwned-detective.py The /common/download.php in the web root allows for an unauthenticated user to read any file on the system that the web user has access to. This includes database credentials and any traffic intercepts captured by the system. The "file" parameter is "protected" by inadequate "cipher": base64 followed by rot40, which is trivially reversible. 2) Authenticated Remote Code Execution The restore feature in the "config backup" page extracts a .tar file encrypted with OpenSSL blowfish into the root directory (/) as root. The .tar file should be encrypted with the static key "/tmp/.charlie". Yes, that's the actual key - they pass the wrong argument to OpenSSL. They used -k instead of -kfile, thus the key is the path of the key file rather than the contents of the key file. This enables an attacker to upload a shell into the web root, or overwrite any system files such as /etc/shadow.
