A new WhatsApp vulnerability has attracted the attention of the press and security professionals around the world. We wanted to provide some information and a quick summary.
This post will cover vulnerability analysis and how McAfee MVISION Mobile can help.
On May 13th, Facebook announced a vulnerability associated with all of its WhatsApp products. This vulnerability was reportedly exploited in the wild, and it was designated as CVE-2019-3568.
WhatsApp told the BBC its security team was the first to identify the flaw. It shared that information with human rights groups, selected security vendors and the US Department of Justice earlier this month.
The CVE-2019-3568 Vulnerability Explained
WhatsApp suffers from a buffer overflow weakness, meaning an attacker can leverage it to run malicious code on the device. Data packets can be manipulated during the start of a voice call, leading to the overflow being triggered and the attacker commandeering the application. Attackers can then deploy surveillance tools to the device to use against the target.
A buffer overflow vulnerability in WhatsApp VOIP (voice over internet protocol) stack allows remote code execution via a specially-crafted series of SRTP (secure real-time transport protocol) packets sent to a target phone number.
