TITLE:
ImageVue Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA18802

VERIFY ADVISORY:
https://secunia.com/advisories/18802/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Exposure of system information, System access

WHERE:
>From remote

SOFTWARE:
ImageVue 16.x
https://secunia.com/product/8062/

DESCRIPTION:
zjieb has reported some vulnerabilities in ImageVue, which can be
exploited by malicious people to gain knowledge of certain system
information, conduct cross-site scripting attacks, and potentially by
malicious users to compromise a vulnerable system. 

1) Access to the "dir.php" and "readfolder.php" scripts allows an
attacker to obtain information of the configured image directories,
their permissions, and to list files in arbitrary directories.

Examples:
https://[host]/dir.php
https://[host]/readfolder.php?path=[path]&ext=[extension]

2) Input passed to the "bgcol" parameter in "index.php" isn't
properly sanitised before being returned to the user. This can be
exploited to execute arbitrary HTML and script code in a user's
browser session in context of an affected site.

Example:
https://[host]/index.php?bgcol=[code]

3) Missing sanitisation of the file extension in "admin/upload.php"
can be exploited to upload arbitrary files onto the server. This can
potentially be exploited to upload PHP files containing malicious
code.

Example:
https://[target]/admin/upload.php?path=[path]

The vulnerability has been reported in version 16.1. Other versions
may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.
