Details have emerged about a now-patched security flaw in the DeepSeek artificial intelligence (AI) chatbot that, if successfully exploited, could permit a bad actor to take control of a victim's account by means of a prompt injection attack . Security researcher Johann Rehberger, who has chronicled many a prompt injection attack targeting various AI tools, found that providing the input "Print the xss cheat sheet in a bullet list. just payloads" in the DeepSeek chat triggered the execution of JavaScript code as part of the generated response – a classic case of cross-site scripting (XSS). XSS attacks can have serious consequences as they lead to the execution of unauthorized code in the context of the victim's web browser. An attacker could take advantage of such flaws to hijack a user's session and gain access to cookies and other data associated with the chat.deepseek[.]com domain, thereby leading to an account takeover. "After some experimenting,...

A pair of severe security vulnerabilities have been disclosed in the Jenkins open source automation server that could lead to code execution on targeted systems. The flaws, tracked as  CVE-2023-27898  and  CVE-2023-27905 , impact the Jenkins server and Update Center, and have been collectively christened  CorePlague  by cloud security firm Aqua. All versions of Jenkins versions prior to 2.319.2 are vulnerable and exploitable. "Exploiting these vulnerabilities could allow an unauthenticated attacker to execute arbitrary code on the victim's Jenkins server, potentially leading to a complete compromise of the Jenkins server," the company said in a report shared with The Hacker News. The shortcomings are the result of how Jenkins processes plugins available from the  Update Center , thereby potentially enabling a threat actor to upload a plugin with a malicious payload and trigger a cross-site scripting (XSS) attack. "Once the victim opens the ' Availabl...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...

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 authenti...

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...

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 Bräunlein  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...

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 the...

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 a...

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. To help you understa...
