A data exposing problem
The vulnerability, tracked as CVE-2022-22998, is a directory traversal bug, allowing unauthorized access to restricted directories and files. The vulnerability has been given a CVSS v3 severity rating of 9.1, categorizing the flaw as critical.
Western Digital’s brief advisory does not provide much detail regarding the vulnerability, so it is not clear if it is a DLL hijacking bug allowing local privilege elevation or a bug allowing access to unprivileged data locations.
However, Western Digital is advising its customers to update their EdgeRover desktop applications to version 1.5.1-594 or later, released last week to resolve these vulnerabilities.
The flaw was discovered by threat researcher Xavier Danest, who responsibly disclosed it to the vendor.
Western Digital addressed the security problem by correcting the file and directory permissions to prevent unauthorized access and modification.
It is unclear if the vulnerability has been actively exploited, Bleeping Computer has contacted the hardware giant to request more details.

Media collection management apps may appear enticing, especially to users who need to organize several terabytes of data from various sources. Still, one shouldn’t forget that each app comes with its own set of security and privacy risks.
In this case, it’s convenience vs. security, as CVE-2022-22998 could potentially lead to the exposure of the users’ entire private media and data collection.
If you’re worried about this scenario, we suggest that you stick with the default file manager that comes with your OS and keep the number of third-party apps on your system at a minimum.
