CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability was found in Facebook WhatsApp Messenger 2.17.146 on Android (Messaging Software). It has been declared as problematic. This vulnerability affects some unknown functionality of the component SD Card Storage Handler. The manipulation with an unknown input leads to a information disclosure vulnerability. The CWE definition for the vulnerability is CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

** DISPUTED ** Facebook WhatsApp Messenger 2.17.146 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.

The weakness was released 05/18/2017 (Website). The advisory is available at wwws.nightwatchcybersecurity.com. This vulnerability was named CVE-2017-8769 since 05/03/2017. Local access is required to approach this attack. A single authentication is required for exploitation. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1592 by the MITRE ATT&CK project.

The real existence of this vulnerability is still doubted at the moment.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
