The Windows OS and Windows products have always been targets for hackers. This is mostly because both are used by the majority of people around the world. Operating Systems like Windows XP have been around for more than a decade, providing ample opportunity and time to exploit various flaws in it. This Windows help article takes a look at one of the latest attacks.
Recently, it has come to notice that attackers are exploiting a new and unpatched vulnerability in Windows XP and Windows Server 2003, allowing them to execute code with higher privileges than they can possibly have access to.
To be precise, the vulnerability is located in NDProxy.sys, “a system-provided driver that interfaces WAN miniport drivers, call managers, and miniport call managers to the Telephony Application Programming Interfaces services.”
“An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode,” the Software giant said in a security advisory published recently. “An attacker could then install programs; view, change, or delete data; or create new accounts with full administrative rights.”
This is actually an elevation-of-privilege (EoP) vulnerability, not a remote code execution one, which means that the hacker would require prior access to a low-privileged account on the targeted system in order to exploit it.
As per Windows help from Microsoft, this vulnerability is already being exploited in “limited, targeted attacks,” but it normally does not affect Windows installments newer than XP and Server 2003.
The company provided a temporary fix – more of a workaround – that helps in disabling NDProxy.sys. But this will then cause certain services which depend on TAPI, like Remote Access Service, dial-up networking and virtual private networking (VPN), to no longer function properly or function at all.
The software maker credited security vendor FireEye with aiding them in the investigation into the new vulnerability, which is being tracked as CVE-2013-5065.
This EoP vulnerability is being exploited in attacks along with remote code execution vulnerability in older or previous versions of Adobe Reader that were patched in May, FireEye security researchers Xiaobo Chen and Dan Caselden mentioned in a blog post. The exploit attacks computers running Adobe Reader on Windows XP with Service Pack 3, but users who have the latest Adobe Reader versions installed should be protected too, according to them.
The exploit is used in targeted attacks, but FireEye researchers have not yet finished investigating the method used to distribute it and the identity of the targets. The exploit installs malware that connects back to and then communicates with a few hacked websites, the company said through email. But, other information regarding what the malware is designed to do has yet to be completely comprehended.Read more »
