One of the most important software companies NGINX , which is also behind the very popular open-source web server of the same name, is being acquired by its rival, F5 Networks , in a deal valued at about $670 million. While NGINX is not a name that you have ever heard of, the reality is that you use NGINX every day when you post a photo, watch streaming video, purchase goods online, or log into your applications at work. NGINX powers over half of the busiest websites in the world. Majority of sites on the Internet today, including The Hacker News, and hundreds of thousands apps, like Instagram, Pinterest, Netflix, and Airbnb are hosted on web servers running NGINX. NGINX web server is the third most widely used servers in the world—behind only Microsoft and Apache, and ahead of Google. In short, the internet as we know it today would not exist without NGINX. F5 Acquires NGINX to Bridge NetOps and DevOps F5 Networks is the industry leader in cloud and security application...

A set of five critical security shortcomings have been disclosed in the Ingress NGINX Controller for Kubernetes that could result in unauthenticated remote code execution, putting over 6,500 clusters at immediate risk by exposing the component to the public internet. The vulnerabilities (CVE-2025-24513, CVE-2025-24514, CVE-2025-1097, CVE-2025-1098, and CVE-2025-1974 ), assigned a CVSS score of 9.8, have been collectively codenamed IngressNightmare by cloud security firm Wiz. It's worth noting that the shortcomings do not impact NGINX Ingress Controller , which is another ingress controller implementation for NGINX and NGINX Plus. "Exploitation of these vulnerabilities leads to unauthorized access to all secrets stored across all namespaces in the Kubernetes cluster by attackers, which can result in cluster takeover," the company said in a report shared with The Hacker News. IngressNightmare, at its core, affects the admission controller component of the Ingress N...

Russian law enforcement officers have raided the Moscow offices of Nginx—the company behind the world's second most popular web server software—over a copyright infringement complaint filed by Rambler, a Russian Internet portal and email service provider. According to multiple reports from local media and social media, the police conducted searches and has also detained several employees of the company, including Igor Sysoev , the original developer of Nginx and Maxim Konovalov , another co-founder of the company. Over 30% of the websites on the Internet today, including many of the world's most popular sites like Netflix and Twitch, run on the Nginx server. Igor Sysoev created the Nginx web server in the early 2000s and open-sourced it in 2004, after which he founded the company Nginx in 2015 that has now been acquired by F5 Networks , an American technology company, for $ 670 million. According to a copy of the complaint shared on Twitter, Rambler accused that Sys...

Misconfigured Docker API instances have become the target of a new malware campaign that transforms them into a cryptocurrency mining botnet. The attacks, designed to mine for Dero currency, is notable for its worm-like capabilities to propagate the malware to other exposed Docker instances and rope them into an ever-growing horde of mining bots. Kaspersky said it observed an unidentified threat actor gaining initial access to a running containerized infrastructure by exploiting an insecurely published Docker API, and then weaponizing that access to create the illicit cryptojacking network. "This led to the running containers being compromised and new ones being created not only to hijack the victim's resources for cryptocurrency mining but also to launch external attacks to propagate to other networks," security researcher Amged Wageh said . The attack chain is realized through two components: A propagation malware "nginx" that scans the internet for expos...

Three unpatched high-severity security flaws have been disclosed in the  NGINX Ingress controller  for Kubernetes that could be weaponized by a threat actor to steal secret credentials from the cluster.

If you're running any PHP based website on NGINX server and have PHP-FPM feature enabled for better performance, then beware of a newly disclosed vulnerability that could allow unauthorized attackers to hack your website server remotely. The vulnerability, tracked as CVE-2019-11043 , affects websites with certain configurations of PHP-FPM that is reportedly not uncommon in the wild and could be exploited easily as a proof-of-concept (PoC) exploit for the flaw has already been released publicly. PHP-FPM is an alternative PHP FastCGI implementation that offers advanced and highly-efficient processing for scripts written in PHP programming language. The main vulnerability is an "env_path_info" underflow memory corruption issue in the PHP-FPM module, and chaining it together with other issues could allow attackers to remotely execute arbitrary code on vulnerable web servers. The vulnerability was spotted by Andrew Danau, a security researcher at Wallarm while hun...

The maintainers of the NGINX web server project have issued mitigations to address security weaknesses in its Lightweight Directory Access Protocol ( LDAP ) Reference Implementation. "NGINX Open Source and NGINX Plus are not themselves affected, and no corrective action is necessary if you do not use the reference implementation," Liam Crilly and Timo Stark of F5 Networks  said  in an advisory published Monday. NGINX said that the  reference implementation , which  uses LDAP to authenticate users , is impacted only under three conditions if the deployments involve - Command-line parameters to configure the Python-based reference implementation daemon Unused, optional configuration parameters, and Specific group membership to carry out LDAP authentication Should any of the aforementioned conditions be met, an attacker could potentially override the configuration parameters by sending specially crafted HTTP request headers and even bypass group membership re...

E-commerce platforms in the U.S., Germany, and France have come under attack from a new form of malware that targets Nginx servers in an attempt to masquerade its presence and slip past detection by security solutions. "This novel code injects itself into a host Nginx application and is nearly invisible," Sansec Threat Research team  said  in a new report. "The parasite is used to steal data from eCommerce servers, also known as 'server-side Magecart.'"  A free and open-source software, Nginx is a web server that can also be used as a reverse proxy, load balancer, mail proxy, and HTTP cache. NginRAT, as the advanced malware is called, works by hijacking a host Nginx application to embed itself into the webserver process. The remote access trojan itself is delivered via  CronRAT , another piece of malware the Dutch cybersecurity firm disclosed last week as hiding its malicious payloads in cron jobs scheduled to execute on February 31st, a non-existent ca...

If you think that the HTTP/2 protocol is more secure than the standard HTTP ( Hypertext Transfer Protocol ), then you might be wrong, as it took researchers just four months to discover four flaws in the HTTP/2 protocol. HTTP/2 was launched properly just in May last year after Google bundled its SPDY project into HTTP/2 in February in an effort to speed up the loading of web pages as well as the browsing experience of the online users. Now, security researchers from data center security vendor Imperva today at Black Hat conference revealed details on at least four high-profile vulnerabilities in HTTP/2 – a major revision of the HTTP network protocol that the today's web is based on. The vulnerabilities allow attackers to slow web servers by flooding them with innocent looking messages that carry a payload of gigabytes of data, putting the servers into infinite loops and even causing them to crash. The HTTP/2 protocol can be divided into three layers: The transmissio...

Cybersecurity researchers have disclosed a security flaw impacting Microsoft Azure Kubernetes Services that, if successfully exploited, could allow an attacker to escalate their privileges and access credentials for services used by the cluster. "An attacker with command execution in a pod running within an affected Azure Kubernetes Services cluster could download the configuration used to provision the cluster node, extract the transport layer security (TLS) bootstrap tokens, and perform a TLS bootstrap attack to read all secrets within the cluster," Google-owned Mandiant said . Clusters using "Azure CNI" for the "Network configuration" and "Azure" for the "Network Policy" have been found to be impacted by the privilege escalation bug. Microsoft has since addressed the issue following responsible disclosure. The attack technique devised by the threat intelligence firm hinges on accessing a little-known component called Azure WireS...

QNAP, Taiwanese maker of network-attached storage (NAS) devices, on Wednesday said it's in the process of fixing a critical three-year-old PHP vulnerability that could be abused to achieve remote code execution.

German security researchers claim to have found a new practical attack against virtual machines (VMs) protected using AMD's Secure Encrypted Virtualization (SEV) technology that could allow attackers to recover plaintext memory data from guest VMs. AMD's Secure Encrypted Virtualization (SEV) technology, which comes with EPYC line of processors, is a hardware feature that encrypts the memory of each VM in a way that only the guest itself can access the data, protecting it from other VMs/containers and even from an untrusted hypervisor. Discovered by researchers from the Fraunhofer Institute for Applied and Integrated Security in Munich, the page-fault side channel attack, dubbed SEVered, takes advantage of lack in the integrity protection of the page-wise encryption of the main memory, allowing a malicious hypervisor to extract the full content of the main memory in plaintext from SEV-encrypted VMs. Here's the outline of the SEVered attack, as briefed in the paper :...

Various implementations of HTTP/2 , the latest version of the HTTP network protocol, have been found vulnerable to multiple security vulnerabilities affecting the most popular web server software, including Apache, Microsoft's IIS, and NGINX. Launched in May 2015, HTTP/2 has been designed for better security and improved online experience by speeding up page loads. Today, over hundreds of millions of websites, or some 40 percent of all the sites on the Internet, are running using HTTP/2 protocol. A total of eight high-severity HTTP/2 vulnerabilities , seven discovered by Jonathan Looney of Netflix and one by Piotr Sikora of Google, exist due to resource exhaustion when handling malicious input, allowing a client to overload server's queue management code. The vulnerabilities can be exploited to launch Denial of Service (DoS) attacks against millions of online services and websites that are running on a web server with the vulnerable implementation of HTTP/2 , knocking...
