Overview

CVE-2017-8769 is a medium-severity vulnerability. It was published on May 18, 2017 and has a CVSS 3.1 base score of 4.6 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 4.6, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

Facebook WhatsApp Messenger before 2.16.323 for Android uses the SD card for cleartext storage of files (Audio, Documents, Images, Video, and Voice Notes) associated with a chat, even after that chat is deleted. There may be users who expect file deletion to occur upon chat deletion, or who expect encryption (consistent with the application's use of an encrypted database to store chat text). NOTE: the vendor reportedly indicates that they do not "consider these to be security issues" because a user may legitimately want to preserve any file for use "in other apps like the Google Photos gallery" regardless of whether its associated chat is deleted

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
