CVE-2022-29835
WD Discovery's Use of Weak Hashing Algorithm for Code Signing
No known exploitation. EPSS puts it in the 8th percentile. A vendor fix is available.
What to do
The vendor has published a fix. Version details are below where the sources state them.
What it is
From the CVE record
WD Discovery software executable files were signed with an unsafe SHA-1 hashing algorithm. An attacker could use this weakness to create forged certificate signatures due to the use of a hashing algorithm that is not collision-free. This could thereby impact the confidentiality of user content. This issue affects: Western Digital WD Discovery WD Discovery Desktop App versions prior to 4.4.396 on Mac; WD Discovery Desktop App versions prior to 4.4.396 on Windows.
