Packeteer PacketShaper Web Management Denial of Service
Critical: Less critical
Impact: DoS
Where: Local network
Product: Packeteer PacketShaper
http://www.packetshaper.com/
Packeteer PacketShaper is susceptible to a denial of service vulnerability in the web management interface. Requesting a specific URL will cause the device to reboot:
http://(target)/rpttop.htm?OP.MEAS.DATAQUERY=&MEAS.TYPE=
The user must first log in but even read-only "look" access is sufficient.
The vulnerability has been identified in version 7.3.0g2 and 7.5.0g1. However, other versions may be also affected.
Solution:
Restrict network access to the device management interfaces
Snort:
alert tcp $EXTERNAL_NET any -> $HOME_NET $HTTP_PORTS
