Linksys EA6500 <strong>Vulnerability</strong>: Insufficient Validation of Configuration File CVE: None Description The Linksys EA6500 does not properly validate configuration files that are uploaded through the web management interface. With some social engineering and a malicious configuration file, an attacker and gain shell access to the Linksys EA6500. Attack Requirements ♦ The victim must download and then upload the malicious configuration file to the router. Details ♦ Other firmware versions were not tested and may be vulnerable. Recommendations to the Vendor ♦ Configuration files should be validated before they are restored to the router. ♦ Additional information for vendors regarding immediate and long term fixes for these issues can be found here: http://www.securityevaluators.com/content/casestudies/routers/#recommendationsVendors Solution ♦ There is no solution to this problem. Proof of Concept Exploit The "restore router configuration" capability under the Troubleshooting section of the web interface extracts a backed-up configuration file to the file system on the router. By manually creating a malicious "backup" and tricking a Linksys EA6500 administrator into restoring it to the router, an attacker can add or overwrite files, and as a result, run arbitrary shell commands on the router. This could ultimately include uploading a telnet daemon to the router and opening it to the Internet to obtain remote access. 48
