🚨 Understanding Nmap NSE Scripts for FTP & TFTP Vulnerabilities 🚨As cybersecurity professionals, understanding how to identify and exploit vulnerabilities is key to securing systems. Recently, I’ve been diving into Nmap’s NSE (Nmap Scripting Engine) scripts, specifically targeting FTP and TFTP services, and here’s a quick rundown of some important ones:ftp-bounce.nse: Tests for FTP Bounce attacks, where attackers use the FTP server as a middleman for scanning and attacks.ftp-vsftpd-backdoor.nse: Detects a backdoor in vsFTPd 2.3.4, allowing attackers to gain root access.ftp-brute.nse: Performs brute-force attacks on FTP servers to find weak passwords.tftp-version.nse: Gathers TFTP server version details — useful for identifying version-specific vulnerabilities.ftp-proftpd-backdoor.nse: Checks for a backdoor in ProFTPD, inserted maliciously in 2010, allowing remote command execution.ftp-syst.nse: Determines the underlying OS by sending the SYST command to the FTP server.ftp-anon.nse: Tests for anonymous login permissions, which could lead to unauthorized access.ftp-libopie.nse: Checks for OPIE (One-time Passwords in Everything) vulnerabilities.ftp-vuln-cve2010-4221.nse: Exploits ProFTPD 1.3.3c vulnerability (CVE-2010-4221) for remote code execution.tftp-enum.nse: Enumerates files on TFTP servers, potentially exposing sensitive data.🔍 Each of these scripts targets different attack vectors — from brute-force attempts to backdoor exploitation, and they are essential for vulnerability assessments and penetration testing.Staying up-to-date with tools like these is critical in today’s evolving cybersecurity landscape. Let’s continue to build secure systems and mitigate these risks!#CyberSecurity #PenetrationTesting #Nmap #EthicalHacking #WebSecurity #InfoSec #FTP #TFTP #Vulnerabilities

📢Security Flaws in Netgate pfSense Firewall Solution Could Allow Command ExecutionMultiple security vulnerabilities have been uncovered in the open-source Netgate pfSense firewall solution, potentially enabling an attacker to execute arbitrary commands on vulnerable appliances. The issues involve two reflected cross-site scripting (XSS) bugs and one command injection flaw. These vulnerabilities impact pfSense CE 2.7.0 and earlier, as well as pfSense Plus 23.05.1 and earlier.🎯Key Points:1. Vulnerability Details:☣️ The flaws consist of two reflected XSS vulnerabilities (CVE-2023-42325 and CVE-2023-42327) and one command injection vulnerability (CVE-2023-42326). Exploiting these issues could allow an attacker to execute arbitrary code and gain privileges via specially crafted URLs.2. Attack Vector:☣️ An attacker can leverage these vulnerabilities by tricking an authenticated pfSense user (admin user) into clicking on a specially crafted URL containing an XSS payload. This could activate command injection, potentially leading to arbitrary code execution.3. Impact:☣️ Reflected XSS attacks can occur when an attacker delivers a malicious script to a vulnerable web application, and the script is then returned in the HTTP response and executed on the victim's web browser. In the context of pfSense, this allows an attacker to perform actions in the firewall with the victim's permissions.4. Risk Mitigation:☣️ The vulnerabilities have been addressed in pfSense CE 2.7.1 and pfSense Plus 23.09, both released in the previous month. Users are advised to update their installations to the latest versions to mitigate the risk of exploitation.5. Context:☣️ The flaws were responsibly disclosed on July 3, 2023, and fixes were incorporated in the recent pfSense releases. These security issues highlight the importance of prompt software updates to address identified vulnerabilities and enhance cybersecurity.Security researcher Oskar Zeino-Mahmalat, who discovered the flaws, emphasized the potential risk of attackers spying on traffic or attacking services within local networks, given the lax security often present in such environments. 🚧🔐 #pfSense #SecurityFlaws #XSS #CommandInjection #Cybersecurity #threatintelligence #threathunting #threatresearch #threatresearch #cyberawareness #cybersecurity #followformore

🌟 Day 107 of #CyberQuest1095 🌟Web Security – Cheat Sheets & Blind Vulnerabilities:Spent the morning revising notes for an upcoming security assessment. Worked on #XSS and #SQLi cheat sheets and read some insightful blogs about blind-based vulnerabilities.Active Directory – Silver Ticket Attacks:Focused on preparing for #SilverTicket attacks while making detailed notes. Also, spent time reading articles on Kerberoasting, #ACL issues, and delegation attacks within Active Directory environments.API Security – Authorization & JWT Exploitation:In the afternoon, I worked on API security notes, specifically around authorization issues. Reviewed some POCs on exploiting #JWT-based #signature attacks, which enhanced my understanding of API security vulnerabilities.Later Night:Wrapped up the day by reading #bugbounty reports, followed by some time reading books and planning for tomorrow’s tasks.Stay tuned for more updates as I continue on this #CyberQuest1095 journey!#WebSecurity #ActiveDirectory #APISecurity #XSS #SQLInjection #SilverTicket #JWT #LearningJourney #Day107

What are the key types of Cross-Site Scripting (XSS) attacks?Cross-site scripting (XSS) is a security vulnerability that allows attackers to inject malicious scripts into web pages viewed by other users. The key types of Cross-Site Scripting (XSS) attacks are:✅ Stored XSS: Malicious scripts are permanently stored on the server (e.g., in a database) and served to users when they request the affected page.✅ Reflected XSS: Malicious scripts are reflected off the web server through URL parameters or other inputs and executed immediately in the user's browser.✅ DOM-Based XSS: Malicious scripts execute through client-side code by manipulating the Document Object Model (DOM) of the page, without involving server-side storage.#XSS #CrossSiteScripting #WebSecurity #CyberSecurity #InfoSec #AppSec #SecurityVulnerability #EthicalHacking #PenTest #WebAppSecurity #SecurityAwareness #DataProtection #Malware #SecurityTesting #SecureCoding
