After Jenkins released the [Security Advisory](https://jenkins.io/security/advisory/2018-12-05/#SECURITY-595) and fixed the dynamic routing vulnerability on 2018-12-05, I started to organize my notes in order to write this Hacking Jenkins series. While reviewing notes, I found another exploitation way on a gadget that I failed to exploit before! Therefore, the part two is the story for that! This is also one of my favorite exploits and is really worth reading :)
This article is mainly about a brief security review on Jenkins in the last year. During this review, we found 5 vulnerabilities including: CVE-2018-1999002(Arbitrary file read vulnerability), CVE-2018-1000600(CSRF and missing permission checks in GitHub Plugin), CVE-2018-1999046(Unauthorized users could access agent logs), CVE-2018-1000861(Code execution through crafted URLs), CVE-2019-pending(Sandbox Bypass in Script Security and Pipeline Plugins)
We reported an overflow vulnerability in the base64 decode function of Exim on 5 February, 2018, identified as CVE-2018-6789. This bug exists since the first commit of exim, hence ALL versions are affected. According to our research, it can be leveraged to gain Pre-auth Remote Code Execution and at least 400k servers are at risk. Patched version 4.90.1 is already released and we suggest to upgrade exim immediately.
