From remote

Cross-Site Scripting

Cross-Site Scripting vulnerabilities allow a third party to manipulate the content or behaviour of a web application in a user's browser, without compromising the underlying system.

Different Cross-Site Scripting related vulnerabilities are also classified under this category, including "script insertion" and "cross-site request forgery".

Cross-Site Scripting vulnerabilities are often used against specific users of a website to steal their credentials or to conduct spoofing attacks.

Exposure of sensitive information

Vulnerabilities where documents or credentials are leaked or can be revealed either locally or from remote.

Manipulation of data

This includes vulnerabilities where a user or a remote attacker can manipulate local data on a system, but not necessarily be able to gain escalated privileges or system access.

The most frequent type of vulnerabilities with this impact are SQL-injection vulnerabilities, where a malicious user or person can manipulate SQL queries.

Hernan Jais has discovered multiple vulnerabilities in OCS Inventory NG, which can be exploited by malicious users to conduct SQL injection attacks and by malicious people to conduct cross-site scripting attacks.

1) Input passed via the "c" parameter to index.php (when "cuaff" is set to any value) is not properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

2) Input passed via the search form for the "BIOS Manufacturer", "BIOS Version", "Computer name", "Description", "Free space", "Gateway", "IP address", "MAC address", "Manufacturer", "Memory", "Model", "Monitor: caption", "Monitor: manufacturer", "Monitor: serial", "Network number", "Processor Speed", "Registry key", "Serial number", "Service pack", "Software", "Tag", or "User" criteria to index.php (when "multi" is set to "1") and via the "All softwares" search form for the "Software name" criteria to index.php (when "multi" is set to "36") is not properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation requires that "magic_quotes_gpc" is disabled.

3) Input passed via the URL is not properly sanitised before being returned to the user within the index.php script. This can be exploited to execute arbitrary HTML and script code in a logged-in user's browser session in context of an affected site.

The vulnerabilities are confirmed in version 1.02.1. Other versions may also be affected.

Update to version 1.02.3, which fixes vulnerability #2.

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