TCP/IP Initial Sequence Number (ISN) Reuse Weakness
The remote host seems to generate Initial Sequence Numbers ISN in a weak manner which seems to solely depend on the source and dest port of the TCP packets. An attacker may exploit this flaw to establish spoofed connections to the remote host. The Raptor Firewall and Novell NetWare are known to b...
CVE-2001-0751
Cisco switches and routers running CBOS 2.3.8 and earlier use predictable TCP Initial Sequence Numbers ISN, which allows remote attackers to spoof or hijack TCP connections...
CVE-1999-1233: Undefined Security Weakness
IIS 4.0 does not properly restrict access for the initial session request from a user's IP address if the address does not resolve to a DNS domain, aka the "Domain Resolution" vulnerability...
CVE-2001-0862: Undefined Security Weakness
Cisco 12000 with IOS 12.0 and line cards based on Engine 2 does not block non-initial packet fragments, which allows remote attackers to bypass the ACL...
SCO UnixWare 7.1.X
Well.. Looks like a insecure file vuln exsists within the system created file when you do the initial install of SCO. Lets take a look here at /var/adm/isl/ifile [email protected] ls -l /var/adm/isl/ifile -rw-r--r-- 1 root root 4691 Sep 24 1999 /var/adm/isl/ifile And we all know the shadow file ...

CVE-1999-1150
Livingston Portmaster routers running ComOS use the same initial sequence number ISN for TCP connections, which allows remote attackers to conduct spoofing and hijack TCP sessions...
CVE-2001-0328
TCP implementations that use random increments for initial sequence numbers ISN can allow remote attackers to perform session hijacking or disruption by injecting a flood of packets with a range of ISN values, one of which may match the expected ISN...

CVE-2001-0288
CVE-2001-0288 pertains to Cisco IOS devices (notably switches/routers running IOS 12.1 and earlier) where TCP Initial Sequence Numbers (ISNs) are predictable. The ISN predictability enables remote attackers to spoof or hijack TCP connections, with impact described as partial confidentiality, inte...

Multiple TCP/IP implementations may use statistically predictable initial sequence numbers
Overview Attacks against TCP initial sequence number generation have been discussed for some time now. It has long been recognized that the ability to know or predict ISNs can lead to TCP connection hijacking or spoofing. What was not previously illustrated was just how predictable one...
