Summary
CVE-2022-50901 is a high-severity Unquoted Search Path or Element (CWE-428) vulnerability in Wondershare Dr.Fone. Its CVSS base score is 8.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Path Interception by Unquoted Path (T1574.009); ranked at the 13.1th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 CM-6 (Configuration Settings) and RA-5 (Vulnerability Monitoring and Scanning).
Deeper analysis
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.
