Description:
A vulnerability has been reported in WS_FTP Server, which can be exploited by malicious users to compromise a vulnerable system.
The vulnerability is caused due to a boundary error when handling user input to the FTP commands "APPE" and "STAT". This can be exploited by supplying a specially crafted argument longer than 255 bytes, which causes a buffer overflow.
Successful exploitation allows execution of arbitrary code with the privileges of the FTP server but requires that the malicious person has been authenticated by the FTP server.
The vulnerability was reported in version 3.4 and has been confirmed in version 4.01. However, other versions may also be affected.
NOTE: A related vulnerability was reported in 2001 in version 2.0.3 but fixed in version 2.0.4.
