We have reported an RCE vulnerability in Redis, which is assigned as CVE-2022-24834. The patch was released yesterday and we recommend applying it promptly. We will be publishing the writeup and PoC next week. Stay tuned! redis.com/blog/security-…

We will be publishing an English version of the technical series "Fuzzing Farm," which was well-received in Japanese. The series will be released from this week to next week. The final day will feature a technical article explaining the exploitation of CVE-2022-24834. Stay tuned!

Our Fuzzing Farm team is developing and utilizing fuzzers. We will be sharing their work over the next 4 blog posts, starting this week. The first post covers how to find bugs and identify their root cause through fuzzing. ricercasecurity.blogspot.com/2023/07/fuzzin…

This is part 2 of our Fuzzing Farm series. Our team is not only working to develop and utilize fuzzers, but also to evaluate and improve them. In this article, we discuss some pitfalls and insights when evaluating fuzzers. ricercasecurity.blogspot.com/2023/07/fuzzin…

This is part 3 of our Fuzzing Farm series. Our team is also working on 1-day and 0-day exploits. In this article, we explain the process of developing a Proof of Concept (PoC) for undisclosed bugs, using a CVE of Google Chrome as an example. ricercasecurity.blogspot.com/2023/07/fuzzin…

In the final part of our Fuzzing Farm series, we provide technical analysis and a PoC for CVE-2022-24834, an RCE vulnerability in Redis we found.
