Descriptions

FreeBSD 4.1.1 and earlier, and possibly other BSD-based OSes, uses an insufficient random number generator to generate initial TCP sequence numbers (ISN), which allows remote attackers to spoof TCP connections.

EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

Exploit Database EDB-ID : 19522

Publication date : 1999-09-26 22:00 +00:00
Author : Stealth & S. Krahmer
EDB Verified : Yes

source: https://www.securityfocus.com/bid/670/info A vulnerability in the Linux kernel allows remote users to guess the initial sequence number of TCP sessions. This can be used to create spoofed TCP sessions bypassing some types of IP based access controls. The function 'secure_tcp_sequence_number' in the file 'drivers/char/random.c' at line 1684 is used to generate the initial sequence number. It used the MD4 hash with a set of inputs to generate the new ISN. https://gitlab.com/exploit-database/exploitdb-bin-sploits/-/raw/main/bin-sploits/19522.tar.gz
