{"id":"CVE-2010-20122","state":"PUBLISHED","title":"Xftp FTP Client <= 3.0 PWD Response Buffer Overflow","description":"Xftp FTP Client version up to and including 3.0 (build 0238) contain a stack-based buffer overflow vulnerability triggered by a maliciously crafted PWD response from an FTP server. When the client connects to a server and receives an overly long directory string in response to the PWD command, the client fails to properly validate the length of the input before copying it into a fixed-size buffer. This results in memory corruption and allows remote attackers to execute arbitrary code on the client system.","publishedAt":"2025-08-21T20:16:17.595Z","updatedAt":"2026-05-15T11:13:37.303Z","severity":{"score":9.3,"label":"Critical","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","source":"VulnCheck"},"assigner":"VulnCheck","products":["NetSarang Computer, Inc.
