It is possible for an attacker to traverse the web folders of a Savant HTTP Server. Submitting a URL referring to a known directory or file, and appended with specific unicode characters, will disclose the contents of the requested resource. The unicode character in question is '%2f..'.
A problem with the switch firmware could allow a Denial of Service to legitimate users of network resources. Upon booting the switch with SNMP disabled, the service does not handle normal requests. However, by sending an empty UDP packet to the SNMP port, the switch ceases operating.
When a parsing error occurs after a modification operation, crontab will fail to drop privileges correctly for subsequent modification operations. This vulnerability may be exploited to gain root privileges locally.
A problem in the Cisco Hot Standby Routing Protocol (HSRP) makes it possible to deny service to users of network resources. By eavesdropping on HSRP management messages sent over the network, it is possible to create a spoofed message that will reroute all network traffic to a particular system. By doing so, it is possible to prevent traffic from entering or leaving that network.
By submitting the FTP command CD argumented by an asterisk character, the attacker can cause an error message to be generated by WebWeaver which includes the path for the ftp root.
Windows 2000 Internet Printing ISAPI extension contains msw3prt.dll which handles user requests. Due to an unchecked buffer in msw3prt.dll, a maliciously crafted HTTP .printer request containing approx 420 bytes in the 'Host:' field will allow the execution of arbitrary code. Typically a web server would stop responding in a buffer overflow condition; however, once Windows 2000 detects an unresponsive web server it automatically performs a restart. Therefore, the administrator will be unaware of this attack.

A number of TCP/IP stacks are vulnerable to a 'loopback' condition initiated by sending a TCP SYN packet with the source address and port spoofed to equal the destination source and port. When a packet of this sort is received, an infinite loop is initiated and the affected system halts. This is known to affect Windows 95, Windows NT 4.0 up to SP3, Windows Server 2003, Windows XP SP2, Cisco IOS devices & Catalyst switches, and HP-UX up to 11.00.
