Jenkins Security Alert: New Security Flaws Could Allow Code Execution Attacks

Jenkins Security Alert: New Security Flaws Could Allow Code Execution Attacks
Mar 08, 2023 Open Source / Automation Tool
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 ' Available Plug

Latest Atlassian Confluence Flaw Exploited to Breach Jenkins Project Server

Latest Atlassian Confluence Flaw Exploited to Breach Jenkins Project Server
Sep 07, 2021
The maintainers of Jenkins—a popular open-source automation server software—have disclosed a security breach after unidentified threat actors gained access to one of their servers by exploiting a recently disclosed vulnerability in Atlassian Confluence service to install a cryptocurrency miner. The "successful attack," which is believed to have occurred last week, was mounted against its Confluence service that had been deprecated since October 2019, leading the team to take the server offline, rotate privileged credentials, and reset passwords for developer accounts. "At this time we have no reason to believe that any Jenkins releases, plugins, or source code have been affected," the company  said  in a statement published over the weekend. The disclosure comes as the U.S. Cyber Command  warned  of ongoing mass exploitation attempts in the wild targeting a now-patched critical security vulnerability affecting Atlassian Confluence deployments. Tracked as CVE-2

New Report: Unveiling the Threat of Malicious Browser Extensions

New Report: Unveiling the Threat of Malicious Browser Extensions
Dec 06, 2023Browser Security / Privacy
Compromising the browser is a high-return target for adversaries. Browser extensions, which are small software modules that are added to the browser and can enhance browsing experiences, have become a popular browser attack vector. This is because they are widely adopted among users and can easily turn malicious through developer actions or attacks on legitimate extensions. Recent incidents like  DataSpii  and the  Nigelthorn  malware attack have exposed the extent of damage that malicious extensions can inflict. In both cases, users innocently installed extensions that compromised their privacy and security. The underlying issue lies in the permissions granted to extensions. These permissions, often excessive and lacking granularity, allow attackers to exploit them. What can organizations do to protect themselves from the risks of browser extensions without barring them from use altogether (an act that would be nearly impossible to enforce)?  A new report by LayerX, "Unveiling the

Critical Jenkins Server Vulnerability Could Leak Sensitive Information

Critical Jenkins Server Vulnerability Could Leak Sensitive Information
Aug 18, 2020
Jenkins—a popular open-source automation server software—published an advisory on Monday concerning a critical vulnerability in the Jetty web server that could result in memory corruption and cause confidential information to be disclosed. Tracked as CVE-2019-17638 , the flaw has a CVSS rating of 9.4 and impacts Eclipse Jetty versions 9.4.27.v20200227 to 9.4.29.v20200521—a full-featured tool that provides a Java HTTP server and web container for use in software frameworks. "Jenkins bundles Winstone-Jetty, a wrapper around Jetty, to act as HTTP and servlet server when started using java -jar jenkins.war. This is how Jenkins is run when using any of the installers or packages, but not when run using servlet containers such as Tomcat," read the advisory. "The vulnerability may allow unauthenticated attackers to obtain HTTP response headers that may include sensitive data intended for another user." The flaw , which impacts Jetty and Jenkins Core, appears to
