What's Server-Side Request Forgery (SSRF) and How Does It Work ? Server-Side Request Forgery (SSRF) is a type of security vulnerability that allows an attacker to trick a server into making requests to unintended locations on behalf of the attacker. 🦹♂️ This can lead to unauthorized access to internal services, sensitive information disclosure, or even complete system compromise. 💥 Let's explore how SSRF works: ➤ Request Initiation 📤: The attacker tricks the server into making a request to a location of their choice. This usually happens when a web application accepts a user-provided Uniform Resource Locator (URL) to fetch data or upload images. ➤ Request Manipulation 🕵️♂️: The attacker tricks the server by entering a specially crafted URL that targets an internal or sensitive resource, such as a private IP address or a local admin page. The server, without proper checks, processes the request and accesses the targeted resource. ➤ Response Exploitation 🔓: The server, tricked by the attacker, can access internal systems and sensitive information like network details or database credentials. This information is then sent back to the attacker, exposing critical data. Here are some methods to prevent SSRF attacks: 🔍 Input Validation: Ensure that all user-supplied URLs are validated and sanitized before being used in server-side requests. Restrict input to only allow URLs to known, safe domains. ✅ Use of URL Whitelisting: Instead of blacklisting certain domains, maintain a whitelist of allowed URLs or domains. 🚫 Disable Unnecessary Protocols: Block protocols like file://, ftp://, or gopher:// that should not be used or are known to be risky. 🌐 Network Segmentation: Keep sensitive systems isolated from the systems that handle user inputs to minimize the damage in case of an SSRF attack. Understanding and mitigating SSRF is crucial, as it can be a gateway for more severe security breaches. 🛡 Take a look at the animated infographic below, and happy learning! 🙂 ✨ Credits to @SecPro. #cybersecurity #security #informationsecurity #hacking #websecurity #cyberattacks #vulnerabilities #internet #web #klex

𝐓𝐡𝐢𝐧𝐤 𝐲𝐨𝐮𝐫 𝐝𝐚𝐭𝐚 𝐢𝐬 𝐬𝐚𝐟𝐞 𝐣𝐮𝐬𝐭 𝐛𝐞𝐜𝐚𝐮𝐬𝐞 𝐲𝐨𝐮’𝐫𝐞 𝐮𝐬𝐢𝐧𝐠 𝐓𝐂𝐏/𝐈𝐏? Not so fast! Using the wrong port can expose your systems to serious security risks. Let's break it down: 🔴 FTP (Port 21): Sending files with FTP is like handing out your passwords in plain sight. Switch to SFTP on port 22 for encrypted transfers. 🔴 Telnet (Port 23): Telnet sends everything in plaintext—your credentials, your data, everything. Use Secure Shell (SSH) on port 22 instead. 🔴 SMTP (Port 25): Sending emails without encryption? SMTP on port 25 is a snooper's dream. Go for SMTPS on port 587 for secure mail. 🔴 TIME (Port 37): Legacy equipment might still use this, but it's time to move on to NTP on port 123, which is far more reliable and secure. 🔴 DNS (Port 53): DNS is essential, but without encryption, it’s vulnerable. DNS over TLS (DoT) on port 853 keeps your queries private. 🔴 HTTP (Port 80): Browsing with HTTP? Your data is exposed. Switch to HTTPS on port 443 to keep your web traffic secure. 🔴 IMAP (Port 143): Retrieving emails with IMAP on port 143? Your messages are at risk. Secure them with IMAPS on port 993. 🔴 SMB (Port 445): File sharing over SMB on port 445 without encryption? You’re inviting trouble. Consider NFS on port 2049 for a more secure setup. 🔴 LDAP (Port 389): Managing directories with LDAP on port 389 leaves you vulnerable. Upgrade to LDAPS on port 636 to protect your data.

A classic 𝐒𝐞𝐫𝐯𝐞𝐫 𝐒𝐢𝐝𝐞 𝐑𝐞𝐪𝐮𝐞𝐬𝐭 𝐅𝐨𝐫𝐠𝐞𝐫𝐲 attack we observed on one of our hostnames. We saw 8k+ vivid requests in a span of one day. 🤓 Here is a breakdown of this common attack type : ⛑ Attacker registers a hostname under 𝒐𝒂𝒔𝒕.𝒑𝒓𝒐 domain. For example: <𝒂𝒎𝒂𝒃𝒂𝒅𝒈𝒖𝒚>[.]𝒐𝒂𝒔𝒕.𝒑𝒓𝒐 ⛑Attacker injects the <𝒂𝒎𝒂𝒃𝒂𝒅𝒈𝒖𝒚>[.]𝒐𝒂𝒔𝒕.𝒑𝒓𝒐 hostname into the application in places where the server might interact with Common injection points we saw: Query string parameters, HTTP headers like 𝘊𝘍-𝘊𝘰𝘯𝘯𝘦𝘤𝘵𝘪𝘯𝘨-𝘐𝘗, 𝘍𝘳𝘰𝘮 , 𝘟-𝘍𝘰𝘳𝘸𝘢𝘳𝘥𝘦𝘥-𝘍𝘰𝘳, 𝘈𝘤𝘤𝘦𝘱𝘵-𝘊𝘩𝘢𝘳𝘴𝘦𝘵 etc. ⛑Trick the server into interacting with this hostname by injecting a query string parameter as shown in snapshot ⛑The moment the app server caves in and interacts with this hostname, the attacker would get a detailed log of the server. The interaction can be DNS, HTTP or a simple tcp connection attempt ⚡ A bit about 𝐎𝐀𝐒𝐓 𝐬𝐞𝐫𝐯𝐢𝐜𝐞: Out-of-Band Application Security Testing (OAST) is a service used by attackers to identify vulnerabilities. When interacted with it, this tool can provide verbose info like timestamp, IP address, HTTP headers etc. Using this, attackers can: exfiltrate sensitive data, access internal services behind firewalls and most importantly can execute code or commands on the server. #securityawareness #cloudsecurity #cybersecurity #infosec #internetsecurity

Data from our "Anatomy of an API" report shows that 51% of all requests don’t have any form of #authentication. API authentication is the most basic form of #APIsecurity, where each client gets a unique key that identifies them when making requests. That allows API owners to control how, when, and in what capacity they can access the API. ------------ ❗ 👉 At Treblle's we take API Security seriously. That's why we made a product that is designed to meticulously scrutinize each API request with more than 15 automated comprehensive checks, ensuring robust security measures are in place. It alerts your team to potential vulnerabilities, thus safeguarding your strategic APIs against emerging threats. If you are looking at possible solutions that can fortify your #API infrastructure, we'd love to show you that in a 🙌 demo 🙌 and demonstrate the ways in which our security product can seamlessly protect your critical APIs, ensuring they remain secure and operational amidst the evolving digital landscape.

Day 25/100 – Path Traversal Vulnerability 🚧 Path traversal, also known as directory traversal, is a critical web security vulnerability that allows attackers to access files and directories outside the intended root folder of a web application. 🚨 🛠️ How it works: Attackers manipulate file paths by injecting special sequences like ../ to navigate directories. For example, a poorly validated file request can be abused as: https://lnkd.in/en3FbsCJ Here, the attacker is trying to access the system’s /etc/passwd file, potentially exposing sensitive data! 🛡️ How to prevent it: *Validate & Sanitize Input: Only allow specific, expected file paths and strip dangerous characters. *Whitelist Directories: Only allow access to predefined directories. *Use Secure APIs: Implement file-handling libraries that prevent directory traversal. *File Permissions: Ensure sensitive files are not accessible, even if traversal occurs. 🔐 Why it matters: Path traversal can expose configuration files, sensitive user data, or even system credentials. Proper input validation and file access controls are critical to preventing these attacks. Keep your applications secure by staying vigilant! 🚀 #CyberSecurity #100DaysOfCyber #PathTraversal #EthicalHacking #WebSecurity #OWASP #Infosec
