Open eClass – CVE-2024-26503: Unrestricted File Upload Leads to Remote Code Execution

During an assessment, I identified a severe security vulnerability within Open eClass, an e-learning platform extensively utilized across educational institutions, notably within Greece, where it is deployed by virtually all Greek Universities and educational entities. Open eClass, developed by GUnet (Greek Universities Network), is instrumental in delivering asynchronous e-learning services. The vulnerability, cataloged under CVE-2024-26503, involves an unrestricted file upload flaw that enables remote code execution (RCE), impacting versions 3.15 and earlier of the platform. This critical security lapse presents a significant risk, potentially allowing unauthorized access and control over the system, thereby compromising the integrity and security of the educational infrastructure. Affected Versions: ● version <= 3.15 CVSSv3.1 Base Score: 9.1 ( Critical ) CVSSv3.1 Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H Exploitation Guide The vulnerability can be exploited

How I Use Obsidian for Penetration Testing, CVE Hunting, and Studying

In the ever-evolving realm of cyber security, the tools and techniques at our disposal are as varied as the threats we aim to counteract. Among these tools, note-taking applications play a pivotal role, not just in organizing our thoughts but in streamlining our entire workflow. Today, I'm excited to share how Obsidian, a tool I embraced over two and a half years ago while preparing for my eJPT exam, has become an indispensable ally in my journey through penetration testing, CVE hunting, and continuous learning. If you're not yet familiar with Obsidian, it's a robust note-taking application that operates on a local collection of plain text Markdown files. What sets it apart is its capability to interlink ideas, forming an expansive web of knowledge that is both intuitive and comprehensive to explore. Through considerable customization, I've developed what I consider to be an ideal method for consolidating notes, insights, and projects into a unified workspace. Here'

OSWE: The Review That You Should Read

In the ever-evolving world of cybersecurity, certifications are often seen as milestones that mark one's journey from novice to expert. Among the myriad of certifications available, OffSec Web Expert (OSWE) stands out as one of the most challenging and respected. If you're considering pursuing OSWE, or if you're simply curious about what it entails, this review is for you. What is OSWE? OSWE, or OffSec Web Expert, is an advanced certification offered by OffSec, a renowned organization in the cybersecurity community. The certification is aimed at professionals who want to demonstrate their expertise in conducting white-box penetration testing on web applications. Unlike black-box penetration testing, where the tester has no prior knowledge of the target, white-box testing involves having access to the application's source code, allowing for a more thorough and in-depth analysis. The OSWE certification is not just another feather in your cap; it's a rigorous test of
