What is CVE-2010-20122?

Xftp FTP Client versions up to 3.0 (build 0238) suffer from a stack-based buffer overflow vulnerability. This flaw is triggered when the client receives an excessively long response to the PWD command from an FTP server. The software inadequately verifies the length of the input, leading to memory corruption. This vulnerability enables remote attackers to potentially execute arbitrary code on the client system, posing a significant cybersecurity risk.
