Apache Tomcat Patches Important Remote Code Execution Flaw

Apache Tomcat Patches Important Remote Code Execution Flaw
April 15, 2019Wang Wei
The Apache Software Foundation (ASF) has released new versions of its Tomcat application server to address an important security vulnerability that could allow a remote attacker to execute malicious code and take control of an affected server. Developed by ASF, Apache Tomcat is an open source web server and servlet system, which uses several Java EE specifications such as Java Servlet, JavaServer Pages (JSP), Expression Language, and WebSocket to provide a "pure Java" HTTP web server environment for Java concept to run in. The remote code execution vulnerability ( CVE-2019-0232 ) resides in the Common Gateway Interface (CGI) Servlet when running on Windows with enableCmdLineArguments enabled and occurs due to a bug in the way the Java Runtime Environment (JRE) passes command line arguments to Windows. Since the CGI Servlet is disabled by default and its option enableCmdLineArguments is disabled by default in Tomcat 9.0.x, the remote code execution vulnerability has

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

Default Apache Configuration Can Unmask Tor Hidden Services

Default Apache Configuration Can Unmask Tor Hidden Services
February 01, 2016Unknown
Attention Tor Onion Hosters! A year old loophole in Apache Web Server, uncovered by an unknown Computer Science Student, could potentially unmask the real identity of .onion-domains and servers hidden behind the Tor-network. Although the loophole was reported on Reddit and to the Tor Project months back, it recently came to the limelight soon after a tweet by Alec Muffet , a well-known security enthusiast and current software engineer at Facebook. What is Tor Hidden (.onion) Service? Dark Web websites (generally known as 'onion services') with a special domain name that ends with .onion, are called Tor Hidden Service and reachable only via the Tor network. Tor Hidden Service is a widely popular anonymity network used by Whistleblowers, Underground Markets, Defense Networks and more in order to maintain secrecy over the Internet. An Onion Website can be hosted on the top of any web servers. But, if you are choosing Apache, then you need to rethink.

Researchers found Apache Server-Status Enabled on some popular site like php.net , cisco, nba.com, Cloudflare, Metacafe, Ford, yellow.com, and others. For backgorund, there is  a Module mod_status in   Apache server which allows a server administrator to find out how well their server is performing. A HTML page is presented that gives the current server statistics in an easily readable form. Basically,  mod_status provides information on your apache server activity and performance. The main security risk of using this module is only Information disclosure which includes infomation such as Server uptime, Individual request-response statistics and CPU usage of the working processes, Current HTTP requests, client IP addresses, requested paths, processed virtual hosts. , that could give a potential attacker information about how to attack the web server. Few popular brands showing their status online, discovered by  Daniel Cid from Sucuri : http://php.net/server-statu
