TITLE:
FileCOPA Directory Argument Handling Buffer Overflow

SECUNIA ADVISORY ID:
SA21097

VERIFY ADVISORY:
http://secunia.com/advisories/21097/

CRITICAL:
Moderately critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
FileCOPA 1.x
http://secunia.com/product/6898/

DESCRIPTION:
Secunia Research has discovered a vulnerability in FileCOPA, which
can be exploited by malicious users to compromise a vulnerable
system.

The vulnerability is caused due to an integer underflow error in the
FTP service (filecpnt.exe) when processing directory arguments passed
to certain FTP commands (e.g. "CWD", "DELE", "MDTM", and "MKD"). This
can be exploited to cause a stack-based buffer overflow by passing a
specially crafted, overly long argument (more than 260 bytes) to one
of the affected FTP commands.

Successful exploitation allows execution of arbitrary code.

The vulnerability has been confirmed in version 1.01 released
2006-07-18. Other versions may also be affected.

SOLUTION:
Update to version 1.01 released 2007-07-21.

PROVIDED AND/OR DISCOVERED BY:
