NVD Description

Wondershare Dr.Fone 11.4.9 contains an unquoted service path vulnerability in the DFWSIDService that allows local users to potentially execute arbitrary code. Attackers can exploit the unquoted path in C:\Program Files (x86)\Wondershare\Wondershare Dr.Fone\ to inject malicious executables that would run with…

LocalSystem privileges.

Deeper analysisAI

CVE-2022-50901 is an unquoted service path vulnerability in Wondershare Dr.Fone version 11.4.9, specifically affecting the DFWSIDService. The issue arises from an unquoted path in C:\Program Files (x86)\Wondershare\Wondershare Dr.Fone\, enabling local users to potentially execute arbitrary code. It carries a CVSS score of 8.4 (CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) and maps to CWE-428.

Local attackers can exploit this vulnerability by injecting malicious executables into directories parsed before the legitimate service binary due to the unquoted path. No privileges are required (PR:N), and exploitation allows arbitrary code execution with LocalSystem privileges, resulting in high impacts on confidentiality, integrity, and availability.
