![](https://nsfocusglobal.com/wp-content/uploads/2019/04/APACHE-HTTP-SERVER.jpg)
April 8, 2019
Overview
Recently, Apache Software Foundation released a security advisory, announcing remediation of a privilege escalation vulnerability (CVE-2019-0211) in the Apache HTTP Server. Apache HTTP Server running MPM event, worker or prefork could allow an attacker to gain elevated privileges on the system by executing code in less-privileged child processes or threads (including scripts executed by an in-process scripting interpreter). By manipulating the scoreboard, an attacker could exploit this vulnerability to gain privileges of the parent process (usually root) and execute arbitrary code on the system. (more…)

April 5, 2019
NSFOCUS Security Lab research has seen a dramatic decrease in DDoS attacks between 2017 and 2018. We are in consensus with other TI vendors as to most of the driving factors behind this large scale reduction, except one. This webinar 1 will show why NSFOCUS is breaking from the pack on one of the key factors leading to the significant decrease in DDoS attacks in 2018. (more…)

April 4, 2019
Overview
Recently, a foreign researcher announced a 0-day vulnerability with Microsoft Edge and Internet Explorer (IE). Enticing a user to click a malicious link, an attacker could exploit this vulnerability to bypass the same-origin policy of the two kinds of browsers to launch a universal cross-site scripting (UXSS) attack to steal the user’s sensitive information.

April 2, 2019
Overview
Recently, a foreign researcher discovered a potential vulnerability in the UC browser which may affect hundreds of millions of users around the world. A hidden feature is found in the UC browser to download auxiliary software modules for execution by bypassing some restrictions of an application store. This feature is used to add new functions or install updates to the client, but can also be exploited for man-in-the-middle (MITM) attacks. For example, when a user uses the UC browser to download a PDF file and attempts to open it, an attacker, via an MITM attack, could enable the browser to download a malicious file and finally execute it.

March 29, 2019
Case Analysis
Public shared folders usually house various documents from different departments, many of which contain sensitive data. Sensitive files reside in such folders mainly because people forget to delete them after copying them, thus exposing sensitive data to intranet hackers and rogue insiders. (more…)
Apache Tomcat DoS Vulnerability (CVE-2019-0199) Threat Alert
![](https://nsfocusglobal.com/wp-content/uploads/2019/02/a2.jpg)
March 28, 2019
1 Vulnerability Overview
Recently, The Apache Software Foundation announced the existence of a denial-of-service (DoS) vulnerability in Apache Tomcat HTTP/2. Specifically, the HTTP/2 implementation accepts streams with excessive numbers of SETTINGS frames and also permits clients to keep streams open without reading/writing request/response data. Thus, too many connection requests from clients can cause server-side thread exhaustion. Successful exploitation of this vulnerability would result in a denial of service on the target. (more…)
