CVE-2021-24035 is a vulnerability in WhatsApp
Published on June 11, 2021
A lack of filename validation when unzipping archives prior to WhatsApp for Android v2.21.8.13 and WhatsApp Business for Android v2.21.8.13 could have allowed path traversal attacks that overwrite WhatsApp files.
Weakness Type
Relative Path Traversal
The software uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as ".." that can resolve to a location that is outside of that directory. This allows attackers to traverse the file system to access files or directories that are outside of the restricted directory.
