Description:
Reed Arvin has reported a vulnerability in Golden FTP Server Pro, which can be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to a boundary error in the log parsing functionality when handling entries in the "gftppro.log" log file. This can e.g. be exploited to cause a stack-based buffer overflow by passing an overly long argument (about 336 bytes) to the "USER" FTP command when attempting to log in.
Successful exploitation allows execution of arbitrary code, but either requires that an administrative user afterwards attempts to view the statistics or the FTP server is restarted. Also, to regain normal functionality if the FTP server crashes, the malicious entry in the "gftppro.log" file has to be removed manually.
The vulnerability has been confirmed in version 2.52. Other versions may also be affected.
Solution:
Use another product.
