Is it possible to install IDA Pro without kowning installation password? Linux or MacOS version can find the password directly; Windows version only need 10 minutes to calculate the password. The following is the detailed process.
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.
In order to leverage the vulnerabilities, we put part of efforts into review of Sandstorm's source codes, and tried to escape the sandbox to impact the whole server...
On 23 November, 2017, we reported two vulnerabilities to Exim. These bugs exist in the SMTP daemon and attackers do not need to be authenticated, including CVE-2017-16943 for a use-after-free (UAF) vulnerability, which leads to Remote Code Execution (RCE); and CVE-2017-16944 for a Denial-of-Service (DoS) vulnerability.
