TLDR CVE-2024-30085 is a heap-based buffer overflow vulnerability affecting the Windows Cloud Files Mini Filter Driver cldflt.sys. By crafting a custom reparse point, it is possible to trigger the buffer overflow to corrupt an adjacent _WNF_STATE_DATA object. The corrupted _WNF_STATE_DATA object can be used to leak a kernel pointer from an ALPC handle table object. A second buffer overflow is then used to corrupt another _WNF_STATE_DATA object, which is then used to corrupt an adjacent PipeAttribute object....

Earlier this year, in mid-January, you might have come across this security announcement by GitHub. In this article, I will unveil the shocking story of how I discovered CVE-2024-0200, a deceptively simple, one-liner vulnerability which I initially assessed to likely be of low impact, and how I turned it into one of the most impactful bugs in GitHub’s bug bounty history. Spoiler: The vulnerability enabled disclosure of all environment variables of a production container on GitHub....
Introduction Wi-Fi routers have always been an attractive target for attackers. When taken over, an attacker may gain access to a victim’s internal network or sensitive data. Additionally, there has been an ongoing trend of attackers continually incorporating new router exploits into their arsenal for use in botnets, such as the Mirai Botnet. Consumer grade devices are especially attractive to attackers, due to many security flaws in them. Devices with lower security often contain multiple bugs that attackers can exploit easily, rendering them vulnerable targets....
