Quest Big Brother contains a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary commands. Updates are not available.
Description
Quest Big Brother contains a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary commands.
The vulnerability is due to insufficient validation of user-supplied input processed by the bbntd.exe service used by the affected software. An unauthenticated, remote attacker could exploit the vulnerability and gain the ability to delete or create arbitrary files on a targeted system. Successful exploitation could allow the attacker to execute arbitrary code in the context of the affected application with SYSTEM privileges, resulting in a complete system compromise.
Quest has not confirmed this vulnerability and software updates are unavailable.
Warning Indicators
Quest Big Brother version 4.40 is vulnerable. Other versions may also be affected.
IntelliShield Analysis
To exploit the vulnerability, an attacker would need access to trusted, internal networks. This access requirement may limit the likelihood of a successful attack.
Vendor Announcements
Vendor announcements are not available.
Impact
An unauthenticated, remote attacker could exploit the vulnerability to execute arbitrary commands on a targeted system with SYSTEM privileges. Successful exploitation could result in a complete system compromise.
Technical Information
The vulnerability is due to insufficient validation of user-supplied input processed by the bbntd.exe service used by the affected software. Additionally, improper security restrictions imposed by the bbntd.exe service could allow, via directory traversal attacks, the creation, overwrite, or deletion of existing files on the filesystem where the vulnerable service is installed.
An unauthenticated, remote attacker could exploit this vulnerability and gain the ability to delete or create arbitrary files on a targeted system. Successful exploitation could allow an attacker with SYSTEM privileges the ability to execute arbitrary code in the context of the affected application.
