Vulnerability from github – Published: 2025-08-20 18:30 – Updated: 2025-08-20 18:30

Details

Solar FTP Server fails to properly handle format strings passed to the USER command. When a specially crafted string containing format specifiers is sent, the server crashes due to a read access violation in the __output_1() function of sfsservice.exe. This results in a denial of service (DoS) condition.

Severity

8.7 (High)
