CVE-2010-20122 – Xftp FTP Client Stack-Based Buffer Overflow Vulnerability

CVE ID : CVE-2010-20122

Published : Aug. 21, 2025, 9:15 p.m. | 1 hour, 8 minutes ago

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.

Severity: 9.3 | CRITICAL
