TITLE

Crestron AirMedia AM-100 contains multiple vulnerabilities

Trust: 0.8

sources: CERT/CC: VU#603047

DESCRIPTION

Directory traversal vulnerability in cgi-bin/login.cgi on Crestron AirMedia AM-100 devices with firmware before 1.4.0.13 allows remote attackers to read arbitrary files via a .. (dot dot) in the src parameter. The Crestron AirMedia AM-100 with firmware prior to version 1.4.0.13 is vulnerable to path traversal and command injection. CrestronAirMediaAM-100 is a gateway product from Crestron Electronics of the United States. Crestron AirMedia AM-100 is prone to a directory-traversal vulnerability and a command-injection vulnerability because it fails to sufficiently sanitize user-supplied input. Crestron AirMedia AM-100 running firmware versions 1.1.1.11 through 1.2.1 are vulnerable. ================================================================= # Crestron AM-100 (Multiple Vulnerabilities) ================================================================= # Date: 2016-08-01 # Exploit Author: Zach Lanier # Vendor Homepage: https://www.crestron.com/products/model/am-100 # Version: v1.1.1.11 - v1.2.1 # CVE: CVE-2016-5639 # References: # https://medium.com/@benichmt1/an-unwanted-wireless-guest-9433383b1673#.78tu9divi # https://github.com/CylanceVulnResearch/disclosures/blob/master/CLVA-2016-05-001.md Description: The Crestron AirMedia AM-100 with firmware versions v1.1.1.11 - v1.2.1 is vulnerable to multiple issues. 1) Path Traversal GET request: http://[AM-100-ADDRESS]/cgi-bin/login.cgi?lang=en&src=../../../../../../../../../../../../../../../../../../../../etc/shadow 2) Hidden Management Console http://[AM-100-ADDRESS]/cgi-bin/login_rdtool.cgi The AM-100 has a hardcoded default credential of rdtool::mistral5885 This interface contains the ability to upload arbitrary files (RD upload) and can enable a telnet server that runs on port 5885 (RD Debug mode). 3) Hardcoded credentials The default root password for these devices is root::awind5885 Valid login sessions for the default (non-debugging) management interface are stored on the filesystem as session01, session02.. etc. Cleartext credentials can be read directly from these files
