A journey into the Pwn2Own contest. Part 1: Netgear RAX30 router WAN vulnerabilities

In this blog post we discuss the details of two vulnerabilities we discovered in the Trusted Platform Module (TPM) 2.0 reference implementation code. These two vulnerabilities, an out-of-bounds write (CVE-2023-1017) and an out-of-bounds read (CVE-2023-1018), affected several TPM 2.0 software implementations (such as the ones used by virtualization software) as well as a number of hardware TPMs.

This blog post presents a post-exploitation approach to inject code into KeePass without process injection. It is performed by abusing the cache resulting from the compilation of PLGX plugin.

Following our presentation at Black Hat USA, in this blog post we provide some details on CVE-2022-20233, the latest vulnerability we found on Titan M, and how we exploited it to obtain code execution on the chip.

In this blog post, we present a new vulnerability dataset composed of thousands of vulnerabilities aimed at helping security practitioners to develop, test and enhance their tools. Unlike others, this dataset contains both the vulnerable and fixed states with source data.

This post is a quick vulnerability report summary for a vulnerability we found while fuzzing the TCP/IP stack CycloneTCP.

In this blog post we analyze a denial of service vulnerability affecting the IPv6 stack of Windows. This issue, whose root cause can be found in the mishandling of IPv6 fragments, was patched by Microsoft in their February 2021 security bulletin.

This blog post provides details about four vulnerabilities we found in the IPv6 stack of FreeBSD, more specifically in rtsold(8), the router solicitation daemon. The bugs affected all supported versions of FreeBSD, and the most severe of them could allow an attacker attached to the same physical link to gain remote code execution as root on vulnerable systems. The vulnerabilities were discovered and reported to FreeBSD Security Team in November 2020. FreeBSD issued fixes for these bugs on December 1st, 2020 along with security advisory FreeBSD-SA-20:32.rtsold.

This blog post analyzes the vulnerability known as "Bad Neighbor" or CVE-2020-16898, a stack-based buffer overflow in the IPv6 stack of Windows, which can be remotely triggered by means of a malformed Router Advertisement packet.

This third article from the Samsung's TrustZone series details some vulnerabilities that were found and how they were exploited to obtain code execution in EL3.
