An authenticated attacker can upload a PHP file and bypass the. 9 CVE-2021-37292 MISC MISC ritecms - ritecms RiteCMS version 3.1.0 and below suffers from a remote code execution vulnerability in the admin panel. A malicious user can log in using the backdor account with admin highest privileges and obtain system control. A remote unprivileged malicious attacker could potentially exploit this vulnerability, leading to full system access 10 CVE-2022-26854 MISC kevinlab - 4st_l-bems An Access Control vulnerability exists in KevinLAB Inc Building Energy Management System 4ST BEMS 1.0.0 due to an undocumented backdoor account. 10 CVE-2021-43517 MISC dell - emc_powerscale_onefs Dell PowerScale OneFS, versions 8.2.x-9.2.x, contain risky cryptographic algorithms. 10 CVE-2021-36287 MISC foscam - fi9805e_firmware FOSCAM Camera FI9805E with firmware V4.02.R12.00018510.10012.143900.00000 contains a backdoor that opens Telnet port when special command is sent on port 9530. In this article, we will focus on how to use this vulnerability and propose a python script that exploits CBC mode to decrypt a message encrypted in AES-CBC.Vulnerability Summary for the Week of ApCISA Bulletins / 19mo Original release date: ApLast revised: ApHigh Vulnerabilities Primary Vendor - Product Description Published CVSS Score Source & Patch Info dell - emc_unity_operating_environment Dell VNX2 for file version 8.1.21.266 and earlier, contain an unauthenticated remote code execution vulnerability which may lead unauthenticated users to execute commands on the system. We will then be able to decrypt the entire message except the first block, unless we know the initialization vector. It will only require ensuring that we are able to obtain a response from the server that will serve as an Oracle (we’ll come back to these in more detail later in this report). If attackers successfully exploit this vulnerability, on average, they only need to make 256 SSL 3.0 requests to reveal one byte of encrypted messages. POODLE (Padding Oracle On Downgraded Legacy Encryption) is a man-in-the-middle exploit which takes advantage of Internet and security software clients’ fallback to SSL 3.0. The padding oracle attack is a spectacular attack because it allows to decrypt a message that has been intercepted if the message was encrypted using CBC mode. Padding Oracle attack fully explained and coded from scratch in Python3 Don’t hesitate to tell me if you find some more and I will add them to this list. I couldn’t find them all in one place, so I write them down here. You can find them all around the internet. I had a lot of fun the first time I encountered it in PWK lab as wells as the second time on a HTB machine. Unfortunately, it is not always correcly understood. This is a very well known trick used when the configuration let too many accounts run docker, and you will have to do it in some CTF boxes at least. In this article, I talk about a classic privilege escalation through Docker containers. I wrote a short exploit script using the backdoor to provide a pseudo system shell on the host.ĩ August 2020 Abusing Docker Configuration The breach would have created a backdoor in any websites that ran the compromised version of PHP, enabling hackers to perform remote code execution on the site. The original code was restored after the issue was discovered, but then tampered with a second time. If this version of PHP runs on a server, an attacker can execute arbitrary code by sending the User-Agentt header. PHP verion 8.1.0-dev was released with a backdoor on March 28th 2021, but the backdoor was quickly discovered and removed. PHP 8.1.0-dev Backdoor System Shell Script PHP 8.1.0-dev Backdoor Remote Code Execution Hack The Box writeups: here are walkthroughs to root machines on the HackTheBox website, an online platform for learning and teaching cyber security.
