Millions of WordPress websites are at risks of being completely hijacked by the hackers due to a critical cross-site scripting (XSS) vulnerability present in the default installation of the widely used content management system. The cross-site scripting (XSS) vulnerability, uncovered by the security researcher reported by Robert Abela of Security firm  Netsparker . Wordpress vulnerability resides in Genericons webfont package that is part of default WordPress Twenty Fifteen Theme. Here comes the threat: The XSS vulnerability has been identified as a " DOM-based ," which means the flaw resides in the document object model (DOM) that is responsible for text, images, headers, and links representation in a web browser. The easy-to-exploit DOM-based Cross-Site Scripting (XSS) vulnerability occurred due to an insecure file included with Genericons that allowed the Document Object Model Environment in the victim's browser to be modified. What's DOM-Bas

Nir Goldshlager , Founder/CEO at Break Security known for finding serious flaws in Facebook once again on The Hacker News for  sharing his new finding i.e Stored Cross-site Scripting (XSS) in Facebook Chat, Check In and Facebook Messenger. Stored Cross-site Scripting ( XSS ) is the most dangerous type of Cross Site Scripting. Web applications where the injected code is permanently stored on the target servers, such as in a database, in a message forum, visitor log, comment field, etc 1.) Stored XSS In Facebook Chat: This vulnerability can be used to conduct a number of browser-based attacks including, Hijacking another user's browser, Capturing sensitive information viewed by application users, Malicious code is executed by the user's browser etc. When a user starts a new message within Facebook that has a link inside, a preview GUI shows up for that post. The GUI is used for presenting the link post using a parameter i.e  attachment[params][title],attac

For years, securing a company's systems was synonymous with securing its "perimeter." There was what was safe "inside" and the unsafe outside world. We built sturdy firewalls and deployed sophisticated detection systems, confident that keeping the barbarians outside the walls kept our data and systems safe. The problem is that we no longer operate within the confines of physical on-prem installations and controlled networks. Data and applications now reside in distributed cloud environments and data centers, accessed by users and devices connecting from anywhere on the planet. The walls have crumbled, and the perimeter has dissolved, opening the door to a new battlefield: identity . Identity is at the center of what the industry has praised as the new gold standard of enterprise security: "zero trust." In this paradigm, explicit trust becomes mandatory for any interactions between systems, and no implicit trust shall subsist. Every access request, regardless of its origin,

A vulnerability that a researcher planned to use to compromise an Android cellphone at a hacking contest later this week got squashed after Google fixed the underlying bug in the Android Market. Scio Security CTO Jon Oberheide notified Google of the XSS, or cross-site scripting, bug in the application bazaar because he didn't believe the vulnerability would qualify under terms of the Pwn2Own contest that is scheduled to start on Wednesday. The "incredibly low-hanging naive persistent XSS" allowed attackers to to remotely install malicious apps on Android handsets by tricking users into clicking a link on their phones or computer browsers while logged into a Google account. Oberheide later learned that the vulnerability didn't run afoul of contest rules, allowing him to collect $15,000 and a free handset if he was successful. But he recently discovered Google closed the security hole. The $1,337 awarded to Oberheide under Google's bug bounty program, is little consolati

A short while ago, I decided to prepare a presentation on web vulnerabilities and specifically on XSS attacks. This involved studying the way today's filtration systems work. I selected the most popular Russian social networking website, VKontakte.ru, as a test bed. One thing that grabbed my attention was the updated user status system. The HTML code in the part of the page where users edit their status messages is shown below: As you can see, filtering is performed by the infoCheck() function. The status itself is located in this string: What we have here is two-step filtration. The first step is performed when the user enters the status message. The second step involves converting the status message to text and returning it to the page in the shape in which other users will see it. While the second step definitely works well and it would clearly be impossible to convert to active XSS, things are not as simple where the first step is concerned, so it is that step that we will look

Users of Advanced Custom Fields plugin for WordPress are being urged to update version 6.1.6 following the discovery of a security flaw. The issue, assigned the identifier CVE-2023-30777, relates to a case of reflected cross-site scripting (XSS) that could be abused to inject arbitrary executable scripts into otherwise benign websites. The plugin, which is available both as a free and pro version, has over  two million active installations . The issue was discovered and reported to the maintainers on May 2, 2023. "This vulnerability allows any unauthenticated user from stealing sensitive information to, in this case, privilege escalation on the WordPress site by tricking a privileged user to visit the crafted URL path," Patchstack researcher Rafie Muhammad  said . Reflected XSS  attacks usually occur when victims are tricked into clicking on a bogus link sent via email or another route, causing the malicious code to be sent to the vulnerable website, which reflects the

Details have emerged about a now-patched vulnerability in Azure Service Fabric Explorer ( SFX ) that could lead to unauthenticated remote code execution. Tracked as  CVE-2023-23383  (CVSS score: 8.2), the issue has been dubbed "Super FabriXss" by Orca Security, a nod to the  FabriXss flaw  (CVE-2022-35829, CVSS score: 6.2) that was fixed by Microsoft in October 2022. "The Super FabriXss vulnerability enables remote attackers to leverage an XSS vulnerability to achieve remote code execution on a container hosted on a Service Fabric node without the need for authentication," security researcher Lidor Ben Shitrit  said  in a report shared with The Hacker News. XSS refers to a kind of  client-side code injection  attack that makes it possible to upload malicious scripts into otherwise trusted websites. The scripts then get executed every time a victim visits the compromised website, thereby leading to unintended consequences. While both FabriXss and Super FabriXss

Scammers have again targeted more than one billion active users of the popular social networking giant Facebook, to infect as many victims as possible. Not by serving fake post, neither by providing malicious video link, instead this time scammers have used a new way of tricking Facebook users into injecting or placing malicious JavaScript or client-side code into their web browsers. This malicious code could allow an attacker to gain access to victims' accounts, thereby using it for fraud, to send spams, and promoting further attacks by posting the scam on timeline to victims' friends. This technique is known as Self Cross-site Scripting or Self XSS. Self-XSS (Self Cross-Site Scripting) scam is a combination of social engineering and a browser vulnerability , basically designed to trick Facebook users' into providing access to their account. Once an attacker or scammer gets access to users' Facebook account, they can even post and comment on things on users' behalf.

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
