In this user guide, we will discover some possible causes that might cause microsoft security vulnerabilities, and then we will provide possible fix methods that you can try to fix the issue.
Speed up your PC in minutes
2021 has been a bad year for Microsoft as vulnerabilities were discovered in its biggest products.
So far, 2021 has proved to be something of an Annus horribilis insurance policy for tech giant Microsoft, with numerous vulnerabilities affecting several of its core services, including Active Directory, Exchange, and Azure. Microsoft is absolutely no stranger to attackers trying to exploit known vulnerabilities and zero vulnerabilities By the day, but the frequency and mechanism of the incidents it has experienced since early March have resulted in the technology falling to the ground at least once for a moment, or alternatively two. .
How secure is Microsoft Security?
Your device will actively level up once you focus on Windows. Windows Security constantly scans for spyware (malware), viruses, and security threats. In addition to this safe haven, real-time updates are automatically downloaded to help the support team protect your device from threats.
The following is a timeline of security events that took place at Microsoft in 2021, why this method remains vulnerable to major vulnerabilities and attacks, and an assessment of its actual response throughout the year, according to industry experts in the cybersecurity sector.
2. March: Vulnerability In Microsoft Exchange
Is Microsoft having security issues?
Microsoft said that this task exposed several serious vulnerabilities in Windows 11 and even in other versions, including Windows 10.The fixes occurred during “Patch Tuesday” in January 2022, the evening of the month in which a series of patches are released to successfully address vulnerabilities. software problems.
The first major server security breach occurred in March when Microsoft reported vulnerability CVE-2021-26855 on its Exchange server. The vulnerability was launched remotely, but could be exploited via a protocol on one or more routers. Although this type of attack was considered easy, Microsoft reported that CVE-2021-26855 was successfully exploited and the attackers did not need permissions to access files/settings.
In addition, the vulnerability can be exploited without human intervention, resulting in maximum loss of privacy and protection. On pageAfter updating the vulnerability, he wrote: “This vulnerability is part of a chain of attacks. The original attack requires this capability to establish untrusted connections to port 443 of the Exchange server. You can protect against this by restricting untrusted connections or by setting up a VPN. separating external access to the Exchange server will only protect against the first part of the attack, and several other parts of the chain can sometimes be triggered if the attacker already has access or can convince the owner to open a malicious file. and recommended that updates be installed externally on the Exchange servers immediately.
8. June: Microsoft Discovers Six Zero-day Vulnerabilities
Microsoft has released fixes for home surveillance issues affecting various Windows services that already have six major vulnerabilities that are being targeted by attackers. According to security researcher Brian Krebs, zero 7 days:
1. July: Windows Print Spooler Vulnerability
Attackers have been discovered exploiting a vulnerability in the Microsoft Windows print spooler called PrintNightmare. The remote configuration vulnerability CVE-2021-34527 affected incorrect privileged list operations in a service and appears to be exploitable using basic user functionality but does not require user interaction. “An attacker who successfully exploited this vulnerability could be able to execute arbitrary code with SYSTEM liberties. The attacker can then program; view, change or delete data; and/or create new accounts with full usage rights,” writes Microsoft.
Recommended minimization included immediate installation of security updates, etc.duration to ensure the following registry keys are set to “0” (zero) and also not defined:
August: Researchers Discover An Autodiscover Vulnerability In Microsoft Exchange
Researchers at Guardicore, a security vendor, have discovered and published a vulgar bug in the Microsoft Exchange Autodiscover service that could allow Outlook to trick other third-party Exchange client applications into revealing Windows domain credentials in clear text to access external servers. “It’s an issue both with the design of the simplest way that Microsoft originally implemented [the protocol] and with how a third group implements it. This is a dual problem: it is both a design crisis and an implementation problem with comments,” said Amit Serper, Vice President. President of Security Research.
Is there a security issue with Windows 10?
The National Security Agency has discovered serious vulnerabilities in the Microsoft Windows 10 operating system that could allow scammers to intercept seemingly safe messages. But instead of using the bug for their own intelligence purposes, the NSA warned Microsoft so the system could be fixed for everyone.
During this time, Microsoft began to explore and developDevelop methods to reduce the threat and protect clients. “We are committed to the Coordinated Vulnerability Disclosure Marketplace, a collaborative approach widely used across the industry that reduces unnecessary risk to customers before issues become public. Unfortunately, this issue was not brought to our attention until the marketing analytics team reported it to this publication, so today we learned the main claims,” Jones, Jeff Online Director of Microsoft, said in an emailed statement. Serper explained that Guardicore didn’t actually contact Microsoft because each of our major issues with URL-generating URL auto-discovery is not a zero issue. day and has been known since 2017.
26. August: Researchers Access Data From Thousands Of Microsoft Azure Clients
Wiz researchers have gained full and unrestricted access to the accounts and databases of thousands of different Microsoft Azure customers due to a series of bugs affecting Azure’s flagship database service, Cosmos DB . ChaosDB, calledCreated by the researchers, it allowed any user to download, delete or manipulate a large collection associated with commercial databases in a simple way and without other types of identifiers.
Why is Microsoft so bad at security?
Errors in Windows In a bulletin, Microsoft stated that the “privilege escalation” vulnerability is widespread due to overly permissive access control lists (ACLs) on several system tracks, including the Security Accounts Manager (SAM) database.
