GitHub Enterprise SAML Authentication Bypass (CVE-2024-4985 / CVE-2024-9487)

Introduction In light of the recent Ruby-SAML bypass discovered in GitLab, we set out to examine the SAML implementation within GitHub Enterprise. During our research, we identified a significant vulnerability that enabled bypassing GitHub’s SAML authentication when encrypted assertions were in use. This blog post will provide an in-depth look at GitHub Enterprise’s SAML implementation and analyze the specific code issue that permitted this bypass. Although we uncovered this vulnerability inde

Ruby-SAML / GitLab Authentication Bypass (CVE-2024-45409)

Introduction In this blog post, we will analyze CVE-2024-45409, a critical vulnerability impacting Ruby-SAML, OmniAuth-SAML libraries, which effectively affects GitLab. This vulnerability allows an attacker to bypass SAML authentication mechanisms and gain unauthorized access by exploiting a flaw in how SAML responses are handled. The issue arises due to weaknesses in the verification of the digital signature used to protect SAML assertions, allowing attackers to manipulate the SAML response a

Hacking Apple - SQL Injection to Remote Code Execution

Introduction In our last blog post, we delved into the inner workings of Lucee and took a look at the source code of Masa/Mura CMS, and the vastness of the potential attack surface struck us. It became evident that investing time in understanding the code could pay off. After dedicating a week to our exploration, we stumbled upon several entry points for exploitation, including a critical SQL injection flaw that we were able to exploit within Apple's Book Travel portal. In this blog post, we a

Hello Lucee! Let us hack Apple again?

Last year we conducted an in-depth analysis of multiple vulnerabilities within Adobe ColdFusion, we derived valuable insights, one of which revolved around CFM and CFC handling, parsing and execution. We wondered if there are any other CFML Servers. Does this ring a bell? Allow us to introduce Lucee. We've previously compromised Lucee's Admin panel, showcasing a pre-auth Remote Code Execution (RCE) on multiple Apple servers that utilized Lucee as its underlying server. Our journey led us throug

Introduction While testing request pipelining on multiple programming language built-in servers, we observed strange behavior with PHP’s. As we delved deeper, we discovered a security bug in PHP that could expose the source code of PHP files as if they were static files rather than executing them as intended. Upon further testing, we found that the vulnerability was not present in the latest PHP release. We conducted further tests on different versions of PHP to determine when the bug was fixe
