Microsoft Exchange Servers are becoming increasingly vulnerable to cyberattacks due to unpatched security vulnerabilities. Microsoft has recently released several critical patches for Exchange Servers, but it is still not enough to prevent possible cyberattacks. It is important for organizations to keep up with the latest security developments in order to shield their networks from these types of threats.
A recent Microsoft Security Advisory (2100318) discloses a series of security flaws in Microsoft Exchange Server, including CVE-2020-0688, CVE-2020-0692, CVE-2020-1020, CVE-2020-1021, CVE-2020-1036, CVE-2020-1040, CVE-2020-1043, CVE-2020-1050, CVE-2020-1051, CVE-2020-1472, and CVE-2020-1473. These vulnerabilities, if not patched, can be exploited to hack Microsoft Exchange Servers.
The most serious of these flaws is the CVE-2020-1040 vulnerability, which allows attackers to gain control of a newly installed Exchange server, bypass authentication and inject malicious code. This means that an attacker can access the server and all its data, including emails and file attachments, without needing valid credentials.
Organizations running Exchange Server should update their software to the latest patches immediately. Patch management is one of the most important tasks security administrators should perform regularly in order to protect their networks. Organizations should also monitor network activity for signs of malicious activity, as zero-day exploits or previously unidentified exploits may be used in attacks.
It is also important to note that email server security is not just a matter of running updates and fixes. Healthcare organizations and government agencies, which deal with a lot of sensitive data, should employ more strategic email security measures such as securing user authentication requirements, using advanced encryption methods, configuring granular user permissions, and implementing automated scans for malware.
Cybersecurity professionals need to take proactive measures to secure their organization's Exchange Servers from ongoing cyberattacks. Patching the servers with Microsoft patches is just the start of the process. Organizations need to stay informed about the latest security developments related to Microsoft Exchange Servers and adopt an effective security strategy.
