CSIS-RI-0003: Multiple buffer overflow vulnerabilities in HP ActiveX



Multiple buffer overflow vulnerabilities in HP Software

 

Hewlett-Packard (HP) is the world's largest PC dealer. According to IDC, HP 
shipped 14.7 million units worldwide, a 23.3 percent year-over-year growth and 
a 19 percent market share. 

 

PC's and laptops from HP are often shipped with preinstalled software running 
on Microsoft Windows. The software is designed so the end-user can keep drivers 
and HP software automatically updated. This is done through a ActiveX plugin 
for Microsoft Internet Explorer.

 

CSIS have discovered multiple high-risk vulnerabilities in several parts of 
that specific software. The affected component are found preinstalled on a 
broad range of HP equipment but are also installed when a end user visits HP 
webpage in order to access software updates such as applications, drivers and 
firmware for multiple HP products.

 

We have discovered eight different vulnerabilities of which five should be 
considered highly critical since they allow remote code execution.

 

At least five of these vulnerabilities have been confirmed to work in a typical 
drive-by scenario. All it takes to exploit is to lure a user into visiting a 
hostile and specifically crafted website. The attack could also be done through 
SQL and HTML injection. This would allow, if the system is found vulnerable, to 
run arbitrary code and take complete control of the system or at least with the 
privileges of the logged on user. In order for this scenario to work it would 
only require one of the affected ActiveX objects to be installed and Active 
scripting to be enabled in Microsoft Internet Explorer, which it is by default.

 

The vulnerability was discovered and reported by Dennis Rand from CSIS Security 
Group.

 

HP has released an advisory and update to address these vulnerabilities.
