Apache HTTP Server Privilege Escalation Vulnerability (CVE-2019-0211) Threat Alert
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…)
2018 DDoS Attack Landscape-1

UC Browser Potential Man-in-the-Middle Vulnerability Threat Alert
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.

Apache Tomcat DoS Vulnerability (CVE-2019-0199) Threat Alert
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…)
