New Apache Struts RCE Flaw Lets Hackers Take Over Web Servers

New Apache Struts RCE Flaw Lets Hackers Take Over Web Servers
August 22, 2018Mohit Kumar
Semmle security researcher Man Yue Mo has disclosed a critical remote code execution vulnerability in the popular Apache Struts web application framework that could allow remote attackers to run malicious code on the affected servers. Apache Struts is an open source framework for developing web applications in the Java programming language and is widely used by enterprises globally, including by 65 percent of the Fortune 100 companies, like Vodafone, Lockheed Martin, Virgin Atlantic, and the IRS. The vulnerability ( CVE-2018-11776 ) resides in the core of Apache Struts and originates because of insufficient validation of user-provided untrusted inputs in the core of the Struts framework under certain configurations. The newly found Apache Struts exploit can be triggered just by visiting a specially crafted URL on the affected web server, allowing attackers to execute malicious code and eventually take complete control over the targeted server running the vulnerable applicatio

Whoops, Turns Out 2.5 Million More Americans Were Affected By Equifax Breach

Whoops, Turns Out 2.5 Million More Americans Were Affected By Equifax Breach

Equifax data breach was bigger than initially reported, exposing highly sensitive information of more Americans than previously revealed. Credit rating agency Equifax says an additional 2.5 million U.S. consumers were also impacted by the massive data breach the company disclosed last month, bringing the total possible victims to 145.5 million from 143 million. Equifax last month announced that it had suffered a massive data breach that exposed highly sensitive data of hundreds of millions of its customers, which includes names, social security numbers, dates of birth and addresses. In addition, credit card information for nearly 209,000 customers was also stolen, as well as certain documents with personally identifying information (PII) for approximately 182,000 Equifax consumers. The breach was due to a critical vulnerability ( CVE-2017-5638 ) in Apache Struts 2 framework, which Apache patched over two months earlier (on March 6) of the security incident. Equifax was e

Apache Struts 2 Flaws Affect Multiple Cisco Products

Apache Struts 2 Flaws Affect Multiple Cisco Products
September 12, 2017Swati Khandelwal
After Equifax massive data breach that was believed to be caused due to a vulnerability in Apache Struts , Cisco has initiated an investigation into its products that incorporate a version of the popular Apache Struts2 web application framework. Apache Struts is a free, open-source MVC framework for developing web applications in the Java programming language, and used by 65 percent of the Fortune 100 companies, including Lockheed Martin, Vodafone, Virgin Atlantic, and the IRS. However, the popular open-source software package was recently found affected by multiple vulnerabilities, including two remote code execution vulnerabilities—one discovered earlier this month, and another in March—one of which is believed to be used to breach personal data of over 143 million Equifax users . Some of Cisco products including its Digital Media Manager, MXE 3500 Series Media Experience Engines, Network Performance Analysis, Hosted Collaboration Solution for Contact Center, and Unified C

Critical Flaw in Apache Struts2 Lets Hackers Take Over Web Servers

Critical Flaw in Apache Struts2 Lets Hackers Take Over Web Servers
September 05, 2017Swati Khandelwal
Security researchers have discovered a critical remote code execution vulnerability in the popular Apache Struts web application framework, allowing a remote attacker to run malicious code on the affected servers. Apache Struts is a free, open-source, Model-View-Controller (MVC) framework for developing web applications in the Java programming language, which supports REST, AJAX, and JSON. The vulnerability (CVE-2017-9805) is a programming blunder that resides in the way Struts processes data from an untrusted source. Specifically, Struts REST plugin fails to handle XML payloads while deserializing them properly. All versions of Apache Struts since 2008 (Struts 2.1.2 - Struts 2.3.33, Struts 2.5 - Struts 2.5.12) are affected, leaving all web applications using the framework’s REST plugin vulnerable to remote attackers. According to one of the security researchers at LGTM, who discovered this flaw, the Struts framework is being used by "an incredibly large number and va

New Apache Struts Zero-Day Vulnerability Being Exploited in the Wild

New Apache Struts Zero-Day Vulnerability Being Exploited in the Wild
March 09, 2017Swati Khandelwal
Security researchers have discovered a Zero-Day vulnerability in the popular Apache Struts web application framework, which is being actively exploited in the wild. Apache Struts is a free, open-source, Model-View-Controller (MVC) framework for creating elegant, modern Java web applications, which supports REST, AJAX, and JSON. In a blog post published Monday, Cisco's Threat intelligence firm Talos announced the team observed a number of active attacks against the zero-day vulnerability (CVE-2017-5638) in Apache Struts. According to the researchers, the issue is a remote code execution vulnerability in the Jakarta Multipart parser of Apache Struts that could allow an attacker to execute malicious commands on the server when uploading files based on the parser. "It is possible to perform an RCE attack with a malicious Content-Type value," warned Apache. "If the Content-Type value isn't valid an exception is thrown which is then used to display an erro
