Enterasys Networks Multiple NetSight Products Multiple Vulnerabilities



NetSight is a graphical network management platform combining multiple products into one console. More information can be found at the following URL.


Multiple vulnerabilities exists within the TFTPD and BOOTPD server components of various Enterasys Networks NetSight products.

The TFTPD server component of various Enterasys Networks NetSight products contains a buffer overflow in the file name portion of a request packet. By sending a request packet with a long file name, it is possible to cause an exploitable stack based buffer overflow.

The BOOTPD server component of various Enterasys Networks NetSight products fails to validate the "packet type" field of packets it receives. By sending a UDP packet with a an invalid "packet type" it is possible to cause an the server to exit.


Exploitation of these vulnerabilities allows attackers to cause a denial of service condition or execute arbitrary code on the target system.

These services typically run as an administrative user. As the services use the UDP protocol, the source address of packets could be spoofed. This may allow bypassing of some host based firewall rules designed to limit connections to trusted clients.


iDefense has confirmed the TFTPD and BOOTPD component of the following NetSight packages on the Windows XP and Windows 2000 platform are vulnerable.

 NetSight Console 2.1 NetSight Inventory Manager 2.1 

Previous versions of the products, and versions for other platforms, may also contain vulnerable code, however this has not been confirmed.


These services can be stopped and started from an icon in the system tray. It is recommended that they not be activated unless required. Restricting access to the services to trusted clients may not be a viable option, as the services use the UDP protocol, which an attacker can easily spoof.


iDefense has confirmed that the following releases of Enterasys' NetSight products are no longer vulnerable.

 NetSight Console 2.3.1 build 6 NetSight Inventory Manager 2.2.2 build 4 


A Mitre Corp. Common Vulnerabilities and Exposures (CVE) number has not been assigned yet.
