![]() ![]() You should deploy the updates, or resolve this with your systems administrator or Microsoft support, or ignore following the steps in the Ignoring Specific Vulnerabilities in Scans article. If the results are the same, that means that the patches are indeed missing, and either were not included by Microsoft in the Windows Updates list, or the target machine has problems with Windows Update accuracy. ![]() The preceding scripts leverage the wsusscn2.cab to perform a scan and get the same information on missing updates as LanGuard. For a PowerShell alternative, see Using WUA to Scan for Updates Offline with PowerShell. A quick modern alternative to MBSA’s patch-compliance checking is Using WUA to Scan for Updates Offline, which includes a sample. LanGuard uses the same functionality as Microsoft Baseline Security Analyzer ( MBSA), and it should return the same results as long as the LanGuard Patch Management Database is up to date. Updates available through Windows Updates may be different than the updates offered through WSUS. WSUS is intended for domain IT and Security departments to use and is not the same as the Windows Update service on Windows Operating Systems. LanGuard uses the Microsoft-developed tool Windows Update Agent (WUA) to detect all missing and installed Microsoft patches by providing it a freshly downloaded copy of the WSUS offline Scan Package wsusscn2.cab. Some of these updates LanGuard is detecting are several months old. Don’t leave work without getting these sorted."Īll users should keep an eye out for the Windows update and apply it as soon as possible to be protected from the applicable zero-days and other critical and important-rated vulnerabilities.GFI LanGuard console or Agent scans are reporting that critical Windows updates and patches are missing for the scanned servers and client machines, yet Windows Update check cannot find any new update on that computers as they are fully patched. "The critical patches addressing remote code execution alone are essential given the dramatic increase in work-from-home users," Hollis warned, "but the three addressing the zero-day CVEs are mission-critical in today’s threat landscape. Meanwhile, Richard Hollis, CEO of Risk Crew, called the new security update crucial and overdue. Auto Patch will Lamb said, "alleviate a massive burden off over-stretched IT teams and will help keep systems secure and up to date." "While this month’s Patch Tuesday update is smaller than the fixes released in January, Mark Lamb, CEO of HighGround.io, said, "the fact that three actively exploited Zero Days are being addressed, and that 12 of the bugs relate to the elevation of privileges, this means it’s still a pretty major update." Lamb advises organizations that are able to enable Auto Patch to do so as soon as possible. If successful, the attacker could have those macros running in a document without any warning flagged to the user. It enables an attacker to get around security features, specifically the blocking of potentially malicious Office macros. "This vulnerability is relatively simple to exploit and utilizes local vectors," Walters said, "requiring only low levels of access and no user interaction." CVE-2023-21715: A Microsoft Publisher security feature bypass zero-dayĬVE-2023-21715 is one for users of Microsoft Publisher to worry about. A vulnerability within the Windows Common Log File system driver, CVE-2023-23376, can do just that, according to the Microsoft Security Response Center update guide notification. If successfully exploited, this kind of vulnerability usually allows an attacker with normal user access privileges to boost these up to the system level. MORE FROM FORBES Hacker Reveals Microsoft's New AI-Powered Bing Chat Search Secrets By Davey Winder CVE-2023-23376: A Windows elevation of privilege zero-dayĬVE-2023-23376 impacts much the same userbase as CVE-2023-21823, but rather than being an RCE it is an elevation of privilege (EOP) vulnerability. "It is crucial to install the necessary updates as soon as possible," Walters confirmed. So, if you have disabled Microsoft Store automatic updates, it won't get installed. The really critical takeaway here is that this is one of those patches that isn't implemented via Windows Update but rather via the Microsoft Store. ![]()
