In recent weeks, various internet server issues have occurred around the world, affecting both businesses and end users. Common causes of these disruptions include denial-of-service (DoS) attacks, hardware failures, and network congestion.
DoS attacks aim to overload servers with a flood of requests, making legitimate requests impossible to process. A notable example occurred in January 2023, when the Danish central bank as well as several private banks were paralyzed by such attacks, leaving customers without access to online services.
Physical components such as hard drives or motherboards can fail, causing server problems. For example, hard drive failures can lead to data loss and interruptions, while motherboard failure can affect the entire server operation.
A high volume of data, for example from streaming services or large online events, can lead to network overloads. This affects server performance and can lead to delays or failures.
To prevent such problems and to be able to react to them quickly, continuous monitoring of the servers is essential. Livewatch.de offers a comprehensive solution for this:

In recent months, several critical security vulnerabilities have been discovered in server systems that can potentially have serious consequences for IT security. Some of the most significant vulnerabilities are presented below:
1. CVE-2024-37079: Security vulnerability in VMware vCenter Server
In June 2024, a critical vulnerability was identified in VMware vCenter Server. This vulnerability allows attackers to execute arbitrary code using manipulated packages, leading to a heap buffer overflow and endangering services. VMware has already released a patch that should be installed urgently.
2. CVE-2024-49113: LDAPNightmare in Windows servers
A recently discovered vulnerability in the Windows Lightweight Directory Access Protocol (LDAP) implementation, known as CVE-2024-49113, allows attackers to cause a denial-of-service (DoS) condition by crashing the Local Security Authority Subsystem Service (LSASS). Microsoft fixed this vulnerability in December 2024.
3. CVE-2024-20697: Vulnerability in Windows 11 and Server 2022
A vulnerability in Windows 11 and Windows Server 2022 allows attackers to execute arbitrary code when extracting RAR files. Microsoft fixed this vulnerability in January 2024 and recommends installing the patch and avoiding opening RAR files from unknown sources.
4. CVE-2024-21410: Critical vulnerabilities in Microsoft Exchange servers
The Federal Office for Information Security (BSI) reported in March 2024 that at least 17,000 instances of Microsoft Exchange servers in Germany are vulnerable to critical vulnerabilities. These gaps are already being actively exploited by cyber criminals. The BSI recommends using current versions of Exchange, installing available security updates and configuring the instances securely.
5. CVE-2024-49112: Zero-day vulnerability in Windows and Windows Server
A zero-day vulnerability in Windows and Windows Server enables denial-of-service attacks because it causes the operating system to crash. Windows 10, Windows 11 and Windows Server 2016, 2019 and 2022 are affected. Microsoft fixed this vulnerability in August 2024.
