Software developers forgot to add quotation markings: Bug occurs due to missing quotes

According to security researchers, unquoted path vulnerability allowed the attackers to escalate privilege. Moreover, these types of security flaws are not very commonly occurred. They have around for more than 15 years which have seen in some popular software like ExpressVPN or ForcePoint VPN and many other applications. When we talk about iTunes zero-day vulnerability, the reasons behind this bug is that software developers forget to add quotation markings that should surround the file path Bonjour component which is designed to delivers Apple updates to iTunes software package. However, security researchers found the bug in Windows version of iTune app that there is one of the path used in the code was missing quotes.

Malware Researchers explained: Attacker executes malicious codes on targeted machine by using iTunes zero-day vulnerability

iTunes zero-day bug lies within the process that is digitally signed and is trusted by Operating System. Cyber crooks can import modifications via this bug without AV engines reacting to it. In simple word, we can say that this particular feature makes iTunes zero-day very dangerous. Let’s take have a look the malware researchers explanation about the bug.

As many detection solutions are based on behavior monitoring, the chain of process execution (parent-child) plays a major role in alert fidelity. If a legitimate process signed by a known vendor executes a new malicious child process, an associated alert will have a lower confidence score than it would if the parent was not signed by a known vendor. Since Bonjour is signed and known, the adversary uses this to their advantage.

Researchers suggests: Uninstall Bonjour Component if you are no longer using iTune for Windows

Unquoted path vulnerability allows the hacker to install BitPaymer Ransomware on your Windows instead of Bonjour component. Researchers also says that it might possible to install malicious file as name of “Apple” or “Apple Software” due to bug which is able of being launched the same way but cause big serious in your machine.

Bonjour is separate component and needs to be uninstalled separately from iTunes. If you are no longer using iTune for Windows, then you need to uninstall Bonjour components as well. Now, iTunes zero-day vulnerability has patched with latest Apple updates. So, if you use iTune on your Windows, then you should immediately patch the software with latest Apple updates.

We are researching on the matter “Attacker uses iTunes zero-day to install BitPaymer Ransomware on Windows” very deeply and we will defiantly post an update, if it will come in future. For any suggestions or queries, please write on comment box given below.
