Exploring Wireless Interfaces with Airmon-ng
In the realm of ethical hacking and penetration testing, a thorough understanding of wireless networks is essential. Airmon-ng, a powerful tool in the aircrack-ng suite, provides valuable insights into the wireless interfaces on a system. Let's delve into its various commands and functionalities to optimize your wireless assessment.

1. Displaying Interface Information
To get a comprehensive overview of wireless interfaces on your system, use the following command:

sudo airmon-ng

This command not only lists the available wireless interfaces but also provides crucial details about their status.

2. Checking for Network Managers
Before diving into wireless assessments, it's essential to identify and potentially disable any interfering network managers. Execute the following command:

sudo airmon-ng check

3. Disabling Network Managers
To effectively disable interfering network managers, use the following command:

sudo airmon-ng check kill

Ensure that manual configuration of Internet access is performed if needed, using tools like dhclient or wpa_supplicant on another interface. For access point mode, manual configuration using hostapd is required.

4. Enabling Monitor Mode on wlan0
To set wlan0 to monitor mode, execute the following command:

sudo airmon-ng start wlan0

5. Customizing Channel for Monitor Mode
If your subsequent tool lacks the ability to set the channel, you can manually specify it with the following command:

sudo airmon-ng start wlan0 3

Info

Channel configuration is only necessary when the post-Airmon-ng tool lacks channel-setting capabilities. Aireplay-ng is one such example.

6. Checking Current Channel
Verify the current channel configuration using the iw command:

sudo iw dev wlan0mon info

7. Enhancing Visibility with --verbose
For a more detailed output, use the --verbose option with Airmon-ng:

sudo airmon-ng --verbose

8. Debugging with Airmon-ng
In troubleshooting scenarios, the --debug option provides a wealth of information:

sudo airmon-ng --debug

9. Stopping Monitor Mode
After completing your wireless assessment, revert the interface to its original state with the following command:

sudo airmon-ng stop wlan0mon

Mastering Airmon-ng commands empowers ethical hackers and penetration testers with the insights needed to navigate and assess wireless networks effectively. These commands lay the foundation for a robust and meticulous wireless security assessment.

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'
