PT-2021-2141

Name of the Vulnerable Software and Affected Versions Windows affected versions not specified Description The issue is related to insufficient input validation in the implementation of the TCP/IP protocol in Windows operating systems. This can be exploited by a remote attacker to execute arbitrar...

CVE-2020-0594

Out-of-bounds read in IPv6 subsystem in IntelR AMT and IntelR ISM versions before 11.8.77, 11.12.77, 11.22.77 and 12.0.64 may allow an unauthenticated user to potentially enable escalation of privilege via network access...

CVE-2020-10136

A flaw was found in the IP-in-IP protocol. An unauthenticated attacker can use the IP-in-IP protocol to route network traffic through a vulnerable device, which can lead to spoofing, access control bypasses, and other unexpected network behaviors. Mitigation Systems that have IP in IP kernel...

Internet Bug Bounty: IP-in-IP protocol routes arbitrary traffic by default - CVE-2020-10136

Many machines 150K-180K on the internet accept and route IP over IP by default. IP-in-IP encapsulation is a tunneling protocol specified in RFC 2003 that allows for IP packets to be encapsulated inside another IP packets. This is very similar to IPSEC VPNs in tunnel mode, except in the case of...

IP-in-IP protocol routes arbitrary traffic by default

Overview IP Encapsulation within IP RFC2003 IP-in-IP can be abused by an unauthenticated attacker to unexpectedly route arbitrary network traffic through a vulnerable device. Description IP-in-IP encapsulation is a tunneling protocol specified in RFC 2003 that allows for IP packets to be...

Denial Of Service (DoS)

kernel is vulnerable to denial of service. A divide-by-zero flaw was found in the tcpselectinitialwindow function in the Linux kernel's TCP/IP protocol suite implementation. A local, unprivileged user could use this flaw to trigger a denial of service by calling setsockopt with certain options...

Use-after-free

The kernel is vulnerable to use-after-free. Due to a flaw found in the tcprcvstateprocess function in the Linux kernel TCP/IP protocol suite implementation, if a system using IPv6 had the IPV6RECVPKTINFO option set on a listening socket, a remote attacker could send an IPv6 packet to that system,...

Code injection

An issue was discovered in Mikrotik RouterOS. Crafting a packet that has a size of 1 byte and sending it to an IPv6 address of a RouterOS box with IP Protocol 97 will cause RouterOS to reboot imminently. All versions of RouterOS that supports EoIPv6 are vulnerable to this attack...

CVE-2018-5951: Undefined Security Weakness

An issue was discovered in Mikrotik RouterOS. Crafting a packet that has a size of 1 byte and sending it to an IPv6 address of a RouterOS box with IP Protocol 97 will cause RouterOS to reboot imminently. All versions of RouterOS that supports EoIPv6 are vulnerable to this attack...

Name of the Vulnerable Software and Affected Versions Mikrotik RouterOS affected versions not specified Description An issue was discovered in Mikrotik RouterOS where crafting a packet with a size of 1 byte and sending it to an IPv6 address of a RouterOS box with IP Protocol 97 will cause RouterO...

Linux kernel Network DoS

The vulnerability of the Linux operating system’s kernel is related to the improper handling of a certain interaction between XFRM Netlink messages, IPPROTOAH packets, and IPPROTOIP packets. Exploiting this vulnerability can allow an attacker to cause a service failure...

CVE-2019-6815

The CVE-2019-6815 entry concerns Modicon Quantum PLCs (all firmware versions) with CWE-264 (Permissions, Privileges, and Access Control). The vulnerability arises via Ethernet/IP, enabling denial of service or unauthorized modifications of the PLC configuration due to improper access control. Doc...

CVE-2019-6815: Undefined Security Weakness

In Modicon Quantum all firmware versions, CWE-264: Permissions, Privileges, and Access Control vulnerabilities could cause a denial of service or unauthorized modifications of the PLC configuration when using Ethernet/IP protocol...

Access Controls Bypass

The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. A flaw was found in the way the Linux kernel's TCP/IP protocol suite implementation handled sending of certain UDP packets over sockets that used the UDPCORK option when the UDP Fragmentation Offload UFO...

Privilege Escalation

The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues: A heap-based buffer overflow flaw was found in the Linux kernel's iSCSI target subsystem. A remote attacker could use a specially-crafted iSCSI request to caus...

Input validation

Cisco Sourcefire Snort 3.0 before build 233 mishandles Ether Type Validation. Since valid ether type and IP protocol numbers do not overlap, Snort++ stores all protocol decoders in a single array. That makes it possible to craft packets that have IP protocol numbers in the ether type field which...
