Release Date: 2006/08/04
Last Modified: 2006/08/03
Author: Tamriel [tamriel at gmx dot net]
Application: GeheimChaos <= 0.5

Overview:

Quote from www.chaossoft.de:

"Sofern Sie einen privaten Bereich in Ihre Homepage einbauen
moechten, ist GeheimChaos genau richtig."

Details:

1) Multiple SQL Injection Vulnerabilities in gc.php

...

arround lines 78-79

$tmpQuery = mysql_query("SELECT * FROM $cfgTabelleUserDaten
WHERE username = '$Temp_entered_login'") or die("INSERT ERROR 2");
mysql_query("DELETE FROM $cfgTabelleOnline WHERE username =
'$Temp_entered_login'") or die("DELETE Error 3");

Here attackers can use $Temp_entered_login

...

arround line 103

$tmpQuery = mysql_query("SELECT * FROM $cfgTabelleUserDaten
WHERE email = '$Temp_entered_email'") or die("INSERT ERROR 451");

...

arround line 133

$tmpQuery = mysql_query("SELECT * FROM $cfgTabelleUserDaten
WHERE username = '$Temp_entered_login'") or die("INSERT ERROR 2");

This line can be usefull if you want to perform a login bypass ...

...

2) Multiple SQL Injection Vulnerabilities in registieren.php

...

arround line 50

mysql_query("UPDATE $cfgTabelleUserDaten SET email =
'$form_email', vorname = '$form_vorname', nachname = '$form_nachname',
strasse = '$form_strasse', plzort = '$form_plzort', land =
'$form_land', homepage = '$form_homepage', status = '$usernochfrei',
userpic = '$form_bildpfad', privzeigen = '$form_profilsichtbar',
sprache = '$Temp_sprache', geb_tag = '$form_tag',
geb_monat = '$form_monat', geb_jahr = '$form_jahr', aktivstr =
'$Temp_akt_string', icq = '$form_icq', msn = '$form_msn',
yahoo = '$form_yahoo', profcheck = '0' WHERE userid =
'$geheimchaos->ID'");

...

arround line 170

$tmpQuery = mysql_query("INSERT INTO $cfgTabelleUserDaten
(username,password,email,vorname,nachname,strasse,plzort,land,homepage,

geb_tag,geb_monat,geb_jahr,status,aktivstr,passneu,regdatum,letzterbesuc
h,besuchanzahl,letzteip,userpic,fehlerhaft,profcheck,
privzeigen,sprache,icq,msn,yahoo) VALUES
('$form_username','$Temp_form_pass','$form_email','$form_vorname','$form
_nachname',

'$form_strasse','$form_plzort','$form_land','$form_homepage','$form_tag'
,'$form_monat','$form_jahr','0','$Temp_akt_string','',

'$timestamp','$timestamp','0','$Temp_ip','$form_bildpfad','0','0','$form
_profilsichtbar','$Temp_sprache','$form_icq','$form_msn',
'$form_yahoo')") or die("INSERT ERROR 99");

...

Here the most variables are not checked by the script.

Note:

There are much more sql injection vulnerabilities and possible
cross site scripting vulnerabilities in this script.

Version note:

The "NewsletterChaos" and "ForumChaos" script based on this script.

Solution:

Take a view on PHP's htmlentities and mysql_real_escape_string
functions and try to research the code by your own.
