![]() ![]() Later, in September 2022, Microsoft also evaluated these attacks for a possible newer vector when Zero Day Initiative (ZDI) disclosed CVE-2022-41040 and CVE-2022-41082. Then the adversary is believed to perform the Active Directory reconnaissance attack followed by exfiltration of data. In August 2022, in a small number of targeted attacks, an adversary group, which is believed to be a state sponsored organization, gained initial access and compromised Exchange Servers by chaining CVE-2022-41040 and CVE-2022-41082.Īs per the blog from Microsoft, an adversary group was able to install a widely abused Chopper web shell using which the adversary gained hands-on-keyboard access. They both can also be used separately.īoth these vulnerabilities are also identified as ProxyNotShell. However, authenticated access to the vulnerable exchange server is required to exploit either of these vulnerabilities. As per the guidance provided here, it is believed that CVE-2022-41040 can be used as a stepping stone for the authenticated adversary to remotely exploit another vulnerability, CVE-2022-41082. Managing the updates through the WSUS console is fairly straight forward, you can easily view the different update categories and approve any updates by simply right clicking them.As per Microsoft, currently, the adversaries are exploiting these vulnerabilities for targeted attacks. We can also configure automatic WSUS update approvals rather than going through this manually for every new update. You will then be able to select the computer groups that you wish to approve the update for. In order to approve an update, simply right click it and select approve update. ![]() You’ll also be able to see a percentage of your machines that already have the update installed, which quickly allows you to determine how much more of your environment still requires a particular update. When viewing the updates you will be able to see if they have been approved or not. WSUS Updates: These are updates that are for the WSUS product itself.Security Updates: These include important security fixes for known vulnerabilities as well as malware definition files for Windows Defender.Critical Updates: These target important problems in Microsoft’s products that should be resolved.All Updates: As you can probably guess, this will show all types of updates.In the WSUS console we can view different types of updates, as shown below. We can manage updates through the WSUS console, simply open it up through the Tools menu in Server Manager. ![]() ![]() Regardless of whether you have configured WSUS to require manual or automatic synchronization to download updates, updates must first be approved before they will actually be downloaded and stored locally on the WSUS server.
