WhatsApp has recently fixed critical and high-severity vulnerabilities affecting WhatsApp for Android, WhatsApp Business for Android, WhatsApp for iOS, and WhatsApp Business for iOS. Exploiting these vulnerabilities would be the first step of an attacker installing any malware on the device. In 2019 for example, the Israeli spyware maker NSO Group exploited an audio calling flaw to inject the Pegasus spyware.
WhatsApp Remote Code Execution (RCE) Vulnerabilities
WhatsApp released a patch to fix the remote code execution (RCE) critical vulnerability, CVE-2022-36934. This vulnerability has a CVSSv3 base score of 9.8 and should be prioritized for patching. An integer overflow in WhatsApp could result in RCE in an established video call. It affects assets running:
- WhatsApp for Android prior to v22.214.171.124
- WhatsApp Business for Android prior to v126.96.36.199
- WhatsApp for iOS prior to v188.8.131.52
- WhatsApp Business for iOS prior to v184.108.40.206
WhatsApp released a patch to fix another RCE critical vulnerability, CVE-2022-27492. This vulnerability has a CVSSv3 base score of 7.8 and should be prioritized for patching. Integer underflow in WhatsApp could have caused remote code execution when receiving a crafted video file. It affects assets running WhatsApp for Android v220.127.116.11 and WhatsApp for iOS v18.104.22.168. To exploit this vulnerability, attackers would have to drop a crafted video file on the user’s WhatsApp messenger and convince the user to play it.
These latest vulnerabilities are also affecting the WhatsApp Business app. If you are using it in your organization, it should be a critical fix to prioritize. Successful exploitation of these vulnerabilities would lead to remote code execution and let attackers install malware on the impacted devices. Here’s how to minimize the risk. First, you need to identify the affected assets. Then, update the application to the updated, secure version.
