Thousands of Unprotected Kibana Instances Exposing Elasticsearch Databases

Thousands of Unprotected Kibana Instances Exposing Elasticsearch Databases

April 01, 2019Wang Wei
In today’s world, data plays a crucial role in the success of any organization, but if left unprotected, it could be a cybercriminal’s dream come true. Poorly protected MongoDB, CouchDB, and Elasticsearch databases recently got a lot more attention from cybersecurity firms and media lately. More than half of the known cases of massive data breaches over the past year originated from unsecured database servers that were accessible to anyone without any password. Since the database of an organization contains its most valuable and easily exploitable data, cybercriminals have also started paying closer attention to find other insecure entry points. Though the problems with unprotected databases are no news and are widely discussed on the Internet, I want cybersecurity community and industry experts to pay some attention to thousands of unsafe Kibana instances that are exposed on the Internet, posing a huge risk to many companies. Kibana is an open-source analytics and visualiz
Over 70,000 Memcached Servers Still Vulnerable to Remote Hacking

Over 70,000 Memcached Servers Still Vulnerable to Remote Hacking

Nothing in this world is fully secure, from our borders to cyberspace. I know vulnerabilities are bad, but the worst part comes in when people just don't care to apply patches on time. Late last year, Cisco's Talos intelligence and research group discovered three critical remote code execution (RCE) vulnerabilities in Memcached that exposed major websites including Facebook, Twitter, YouTube, Reddit, to hackers. Memcached is a popular open-source and easily deployable distributed caching system that allows objects to be stored in memory. The Memcached application has been designed to speed up dynamic web applications ( for example php-based websites) by reducing stress on the database that helps administrators to increase performance and scale web applications. It's been almost eight months since the Memcached developers have released patches for three critical RCE vulnerabilities (CVE-2016-8704, CVE-2016-8705 and CVE-2016-8706) but tens of thousands of servers
Critical Flaws in MySQL Give Hackers Root Access to Server (Exploits Released)

Critical Flaws in MySQL Give Hackers Root Access to Server (Exploits Released)

Over a month ago we reported about two critical zero-day vulnerabilities in the world's 2nd most popular database management software MySQL: MySQL Remote Root Code Execution (CVE-2016-6662) Privilege Escalation (CVE-2016-6663) At that time, Polish security researcher Dawid Golunski of Legal Hackers who discovered these vulnerabilities published technical details and proof-of-concept exploit code for the first bug only and promised to release details of the second bug (CVE-2016-6663) later. On Tuesday, Golunski has released proof-of-concept (POC) exploits for two vulnerabilities: One is the previously promised critical privilege escalation vulnerability ( CVE-2016-6663 ), and another is a new root privilege escalation bug ( CVE-2016-6664 ) that could allow an attacker to take full control over the database. Both the vulnerabilities affect MySQL version 5.5.51 and earlier, MySQL version 5.6.32 and earlier, and MySQL version 5.7.14 and earlier, as well as MySQL forks
40,000 UnProtected MongoDB Databases Found on the Internet

40,000 UnProtected MongoDB Databases Found on the Internet

Nearly 40,000 organisations running MongoDB , a NoSQL high performance and cross-platform document-oriented database, are found to be unprotected and vulnerable to hackers. Three students from University of Saarland in Germany at the Centre for IT Security – Kai Greshake, Eric Petryka and Jens Heyens – discovered that MongoDB databases running at TCP port 27017 as a service on several thousands of commercial web servers are easily accessible on the Internet. MongoDB is an open-source database used by companies of all sizes, across all industries for a wide variety of applications. MongoDB is built for scalability, performance and high availability, scaling from single server deployments to large, complex multi-site architectures. By leveraging in-memory computing, MongoDB provides high performance for both reads and writes. The German researchers said that they were able to get "read and write access" to the unsecured MongoDB databases without using any sp
