A significant vulnerability, CVE-2024-37629, has been discovered in SummerNote 0.8.18, allowing Cross-Site Scripting (XSS) via the Code View function. Summernote is a JavaScript library for creating WYSIWYG editors online. An attacker can use XSS to insert harmful scripts into a trusted application or website. An XSS attack often starts with an attacker luring a user to click on a malicious link. According to security researcher Sergio Medeiros, 10,000 web apps have a 0-day vulnerability that can be exploited with a simple XSS payload. Detecting XSS Vulnerability in the Editor Given similar XSS concerns in editors like CKEditor and TinyMCE, the security researcher decided to investigate the WYSIWYG Editor. This led to the SummerNote website, where users can see the WYSIWYG editor’s features on the homepage, along with a GitHub repository URL to examine the codebase. ~First Hackers News To Continue reading this article, click on this link >>> https://lnkd.in/gedPWFm6 #vulnerability #summernote #xss #codeview #javascript #attacker #maliciouslink #securityresearcher #website #zeroday #cyberattack #cybersecurity #cybernews #fhn #firsthackersnews #informationsecurity #latestnews

Hey guys! I recently ran into a challenge with JavaScript prototype chain vulnerabilities, which encouraged me to look into Map as a safer option. I summarized my thoughts. Examine practical examples such as reducing object injection attacks to discover how Maps provide an excellent defense. I hope you find it helpful when you check it out! 📝💡 Link here : https://lnkd.in/eK_5xDqc

A significant vulnerability, tracked as CVE-2024-37629, has been discovered in #SummerNote 0.8.18. It allows Cross-Site Scripting (XSS) via the Code View Function. Summernote is a JavaScript library that helps you create WYSIWYG editors online. An attacker can insert harmful executable scripts into the code of a trustworthy application or website through a technique known as cross-site scripting (XSS). #cybersecurity #xss #javascript #library

I specifically handled the two most important JavaScript attack patterns or vulnerabilities, which are: => Security Details exposed accidentally in the code => Cross Site Scripting (XSS) attacks To prevent my application from these security holes, I made sure that not any sensitive data was present in my code and I used the Sanitize HTML package. You can check my whole code on my GitHub via the link below: https://lnkd.in/edZWvTy7 By the way, I named this little JavaScript demo "JavaScript Security Share My Place".

Anyways, you can leave me a comment for more detail about this application and how it works. And if you are a developer, you can give me some advice about my project or just put a star ⭐ to my repository if you like it.

Hackers are hiding Trojans in fake jQuery packages. Hackers are targeting unsuspecting developers by distributing malicious libraries that masquerade as the popular JavaScript library, jQuery. These booby-trapped packages are then uploaded to common code repositories like npm and GitHub. This sophisticated attack strategy highlights the importance of careful vetting when integrating third-party libraries into your projects. Don't let malicious code compromise your applications or expose your users' data. Here are some tips for safe development: 1. Stick to reputable sources for your libraries. 2. Thoroughly review code before integration. 3. Stay updated on security vulnerabilities. #jQuery #SecurityVulnerability #DeveloperBeware

TL;DR The Google developer documentation includes CSP examples which use domain wildcards (which have been widely cut & pasted), and additionally there are numerous endpoints within the Google eTLDs which are vulnerable to Javascript XSS. These can be combined into an effective attack against any domain with an HTML injection vector that would be otherwise unexploitable. #redteam #blueteam #google #googlecybersecurity
