CVE-2019-0007

The vMX Series software uses a predictable IP ID Sequence Number. This leaves the system as well as clients connecting through the device susceptible to a family of attacks which rely on the use of predictable IP ID sequence numbers as their base method of attack. This issue was found during...

CVE-2019-0007

CVE-2019-0007 affects Juniper Networks Junos OS on the vMX Series, with affected releases: 15.1 versions prior to 15.1F5. The root cause is a predictable IP ID sequence number used by the device, enabling a family of attacks that rely on that predictability to compromise the system and clients pa...

Design/Logic Flaw

The netgetrandomonce implementation in net/core/utils.c in the Linux kernel 3.13.x and 3.14.x before 3.14.5 on certain Intel processors does not perform the intended slow-path operation to initialize random seeds, which makes it easier for remote attackers to spoof or disrupt IP communication by...

CVE-2014-7284

CVE-2014-7284 affects the Linux kernel’s net_get_random_once in net/core/utils.c for 3.13.x and 3.14.x before 3.14.5 on certain Intel CPUs. The issue is that the slow-path to seed randomness is not executed, increasing predictability of TCP sequence numbers, TCP/UDP port numbers, and IP ID values...

USN-2288-1: Linux kernel (Trusty HWE) vulnerabilities

Sasha Levin reported a flaw in the Linux kernel's point-to-point protocol PPP when used with the Layer Two Tunneling Protocol L2TP. A local user could exploit this flaw to gain administrative privileges. CVE-2014-4943 Salva Peiró discovered an information leak in the Linux kernel's media- device...

Nmap NSE net: ipidseq

Classifies a host's IP ID sequence test for susceptibility to idle scan. Sends six probes to obtain IP IDs from the target and classifies them similarly to Nmap's method. This is useful for finding suitable zombies for Nmap's idle scan '-sI' as Nmap itself doesn't provide a way to scan for these...

A paper by Amit Klein (Trusteer): "OpenBSD DNS Cache Poisoning and Multiple O/S Predictable IP ID Vulnerability"

Hello BugTraq Recently I've been looking at the OpenBSD PRNG implementation for DNS transaction ID OpenBSD ported BIND 9 into their code tree, but rolled their own PRNG for the DNS transaction ID field. I discovered a serious weakness in OpenBSD's PRNG, which allows an attacker to predict the nex...

CVE-2006-1242

The ippushpendingframes function in Linux 2.4.x and 2.6.x before 2.6.16 increments the IP ID field when sending a RST after receiving unsolicited TCP SYN-ACK packets, which allows remote attackers to conduct an Idle Scan nmap -sI attack, which bypasses intended protections against such attacks...

CVE-2006-1242

CVE-2006-1242 affects the Linux kernel (2.4.x and 2.6.x up to before 2.6.16). The ip_push_pending_frames function increments the IP ID when sending a RST after unsolicited TCP SYN-ACKs, enabling remote Idle-Scan (nmap -sI) bypassing certain protections. Affected versions: Linux 2.4.x and 2.6.x be...

IP ID could allow to scan a masquerade network.

Hello, I was working on a new implementation of the IPID scann also known has idle scan in the nmap man page or pixie-scan as i call it During my test I think I discover a new way to use this type of scan : Synopsis ------------- Using the gateway of a masquerade network as a witness relay host f...
