3Com NBX ftpd CEL Command Remote Overflow (2)

high Nessus Plugin ID 11184


The remote FTP server is affected by a buffer overflow vulnerability.


The remote FTP server appears to be affected by a buffer overflow that can be triggered with an overly-long 'CEL' command. This problem is similar to the 'aix ftpd' overflow but on embedded VxWorks-based systems like the 3Com NBX IP phone call manager and seems to cause the server to crash. It is known to affected VxWorks ftpd versions between 5.4 and 5.4.2.


If you are using an embedded VxWorks product, please contact the OEM vendor and reference WindRiver field patch TSR 296292. If this is the 3Com NBX IP Phone call manager, contact 3Com.
