A vulnerability, which was classified as critical, has been found in Wondershare Filmora 14.5.16. Affected by this issue is some unknown functionality in the library CRYPTBASE.dll of the file NFWCHK.exe of the component Installer. The manipulation leads to uncontrolled search path. Attacking locally is a requirement. The complexity of an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
The product searches for critical resources using an externally-supplied search path that can point to resources that are not under the product’s direct control.
This might allow attackers to execute their own programs, access unauthorized data files, or modify configuration in unexpected ways. If the product uses a search path to locate critical resources such as programs, then an attacker could modify that search path to point to a malicious program, which the targeted product would then execute. The problem extends to any type of critical resource that the product trusts. Some of the most common variants of untrusted search path are:
