India's Koo, a Twitter-like Service, Found Vulnerable to Critical Worm Attacks

India's Koo, a Twitter-like Service, Found Vulnerable to Critical Worm Attacks
Aug 06, 2021
Koo, India's homegrown Twitter clone, recently patched a serious security vulnerability that could have been exploited to execute arbitrary JavaScript code against hundreds of thousands of its users, spreading the attack across the platform. The vulnerability involves a  stored cross-site scripting flaw  (also known as persistent XSS) in Koo's web application that allows malicious scripts to be embedded directly into the affected web application. To carry out the attack, all a malicious actor had to do was log into the service via the web application and post an XSS-encoded payload to its timeline, which automatically gets executed on behalf of all users who saw the post. The issue was discovered by security researcher  Rahul Kankrale  in July, following which a fix was rolled out by Koo on July 3. Using cross-site scripting, an attacker can perform actions on behalf of users with the same privileges as the user and steal web browser's secrets, such as authentication

Microsoft Edge Bug Could've Let Hackers Steal Your Secrets for Any Site

Microsoft Edge Bug Could've Let Hackers Steal Your Secrets for Any Site
Jun 28, 2021
Microsoft last week rolled out updates for the Edge browser with  fixes for two security issues , one of which concerns a security bypass vulnerability that could be exploited to inject and execute arbitrary code in the context of any website. Tracked as  CVE-2021-34506  (CVSS score: 5.4), the weakness stems from a universal cross-site scripting (UXSS) issue that's triggered when automatically translating web pages using the browser's  built-in feature via Microsoft Translator . Credited for discovering and reporting CVE-2021-34506 are Ignacio Laurence as well as Vansh Devgan and Shivam Kumar Singh with CyberXplore Private Limited.  "Unlike the common XSS attacks, UXSS is a type of attack that exploits client-side vulnerabilities in the browser or browser extensions in order to generate an XSS condition, and execute malicious code," CyberXplore researchers  said  in a write-up shared with The Hacker News. "When such vulnerabilities are found and exploited,

Unpatched Flaw in Linux Pling Store Apps Could Lead to Supply-Chain Attacks

Unpatched Flaw in Linux Pling Store Apps Could Lead to Supply-Chain Attacks
Jun 22, 2021
Cybersecurity researchers have disclosed a critical unpatched vulnerability affecting Pling-based free and open-source software (FOSS) marketplaces for Linux platform that could be potentially abused to stage supply-chain attacks and achieve remote code execution (RCE). "Linux marketplaces that are based on the Pling platform are vulnerable to a wormable [cross-site scripting] with potential for a supply-chain attack," Positive Security co-founder Fabian Br√§unlein  said  in a technical write-up published today. "The native PlingStore application is affected by an RCE vulnerability, which can be triggered from any website while the app is running." The Pling-based app stores impacted by the flaw include — appimagehub.com store.kde.org gnome-look.org xfce-look.org pling.com PlingStore allows users to search and install Linux software, themes, icons, and other add-ons that may not be available for download through the distribution's software center.  T

Flaws in Two Popular WordPress Plugins Affect Over 7 Million Websites

Flaws in Two Popular WordPress Plugins Affect Over 7 Million Websites
Mar 18, 2021
Researchers have disclosed vulnerabilities in multiple WordPress plugins that, if successfully exploited, could allow an attacker to run arbitrary code and take over a website in certain scenarios. The flaws were uncovered in  Elementor , a website builder plugin used on more than seven million sites, and  WP Super Cache , a tool used to serve cached pages of a WordPress site. According to Wordfence, which discovered the security weaknesses in Elementor, the bug concerns a set of  stored cross-site scripting  (XSS) vulnerabilities (CVSS score: 6.4), which occurs when a malicious script is injected directly into a vulnerable web application. In this case, due to a lack of validation of the HTML tags on the server-side, a bad actor can exploit the issues to add executable JavaScript to a post or page via a crafted request. "Since posts created by contributors are typically reviewed by editors or administrators before publishing, any JavaScript added to one of these posts would

LinkedIn with Two-factor authentication and Cross Site Scripting Flaw

LinkedIn with Two-factor authentication and Cross Site Scripting Flaw
Jun 04, 2013
Two Factor Authentication is becoming a standard in the enterprise security space in an attempt to dually secure end users against malicious attacks.  Following Dropbox, Google and virtually everyone else, LinkedIn added two-factor authentication to its login process today. LinkedIn will provide temporary codes for two-factor authentication  through SMS messages. The extra step is designed to lessen the chances of computer hackers breaking into user accounts. To turn on two-step verification on LinkedIn, hit the icon in the top-right corner of the site, click on "Privacy & Settings," and then on "Manage security settings" at the bottom. The site has provided instructions to its 225 million users on how to turn on the optional service. On other side, today @The_Pr0ph3t, whitehat Hacker from Spain reported a Cross Site Scripting Vulnerability in LinkedIn Developer site (developer.linkedin.com).  Flaw still exists on website at the time of writing, and hacker

PayPal Bug Bounty Program - playing fair ?

PayPal Bug Bounty Program - playing fair ?
Nov 13, 2012
Bug Bounty program, where white hat hackers and researchers hunt for serious security vulnerabilities and disclosing them only to the vendor for a patch , In return vendors rewards them with money. Various famous websites like Facebook , Google , Paypal , Mozilla, Barracuda Networks and more other giving away bug bounties in thousands of Dollars to hackers for finding vulnerabilities. Most common vulnerabilities reported maximum time on various sites is Cross site scripting and each month hackers submit lots of such vulnerabilities to companies. In case  your report is duplicate, i.e. Someone else before you submit the same vulnerability - company will reject you from the bug bounty program. But there is no proof or an open Panel where hacker can verify that is someone already reported for same bug before or not. If company reply you - " The bug was already discovered by another researcher" , can you do anything  even after knowing that you are very first per

Cross Site Scripting (XSS) is currently the most common vulnerability in the world. This is vulnerability of some host which allows anyone to inject code/scripts into the page. The injected scripts could be html tags, javascript script, vbscript scripts. A Hacker with virtual name ' Human mind cracker ' expose similar v ulnerabilities in some big and Important sites, like  Israel airline, Myspace, MTV website, Sweden government, Bangladesh bank, Nasa subdomain, Brown University, Afghanistan government website and Rome government website. In a pastebin note , hacker disclose the vulnerabilities and exact working links. These Cross Site Scripting existence is because of the lack of filtering engines to user inputs at websites, forms and web servers. Most of the time readers thinks that XSS is a very minor bug and having very less impact. But if implemented in a better way, that can harm all the visitors who will visit infected site.

How to Minimize Web Application Security Risk !

How to Minimize Web Application Security Risk !
Oct 19, 2012
With Web applications remaining a popular target for attackers, Web app security sometimes seems like a digital version of the " Good, the Bad and the Ugly ." Vulnerabilities in web applications are now the largest vector of enterprise security attacks. Web application security is much more challenging than infrastructure. The top Web application vulnerabilities occur and re-occur time and again. Items such as Cross Site Scripting (XSS), SQL Injection (SQLi) and file inclusion are common vulnerabilities and show up frequently. In his view, the majority of Web application security problems can be solved by applying well known security technology approaches. According to survey results, only 51 percent of organizations currently have coders conduct security testing, and only 40 percent of organizations report they test during development. Vulnerabilities like these fall often outside the traditional expertise of network security managers.
