“20 CVEs affect their Chromium-based Edge browser and 34 affect Azure Site Recovery (up from 32 CVEs affecting that product last month),” Wiseman wrote. Wiseman said despite the record number of vulnerability fixes from Redmond this month, the numbers are slightly less dire. Microsoft notes that the successful exploitation of the weakness requires physical access to the target device, but would allow an attacker to bypass a facial recognition check. Greg Wiseman, product manager at Rapid7, pointed to an interesting bug Microsoft patched in Windows Hello, the biometric authentication mechanism for Windows 10. We’re seeing a continued trend of supply-chain compromise too, making it vital that we ensure developers, and their tools, are kept up-to-date with the same rigor we apply to standard updates.” Patches for their tools should not be overlooked. “So it’s no surprise they are often targeted by more advanced attackers. “Developers are empowered with access to API keys and deployment pipelines that, if compromised, could be significantly damaging to organizations,” he said. The CVSS for this vulnerability is 8.8.”īreen highlighted a set of four vulnerabilities in Visual Studio that earned Microsoft’s less-dire “important” rating but that nevertheless could be vitally important for the security of developer systems. “According to the advisory, ‘An authenticated user could manipulate attributes on computer accounts they own or manage, and acquire a certificate from Active Directory Certificate Services that would allow elevation of privilege to System.’ A system is vulnerable only if Active Directory Certificate Services is running on the domain. “Another critical vulnerability worth mentioning is an elevation of privilege affecting Active Directory Domain Services ( CVE-2022-34691),” SANS wrote. The SANS Internet Storm Center‘s rundown on Patch Tuesday warns that a critical remote code execution bug in the Windows Point-to-Point Protocol ( CVE-2022-30133) could become “wormable” - a threat capable of spreading across a network without any user interaction. That lingering catastrophe is reminder enough that critical Exchange bugs deserve immediate attention. ![]() It’s difficult to believe it’s only been a little more than a year since malicious hackers worldwide pounced in a bevy of zero-day Exchange vulnerabilities to remotely compromise the email systems for hundreds of thousands of organizations running Exchange Server locally for email. The other two critical Exchange bugs are tracked as CVE-2022-24516 and CVE-2022-21980. For attackers focused on Business Email Compromise this kind of vulnerability can be extremely damaging.” With CVE-2022-24477, for example, an attacker can gain initial access to a user’s host and could take over the mailboxes for all exchange users, sending and reading emails and documents. “Exchanges can be treasure troves of information, making them valuable targets for attackers. “If your organization runs local exchange servers, this trio of CVEs warrant an urgent patch,” said Kevin Breen, director of cyber threat research for Immerse Labs. See Microsoft’s blog post on the Exchange Server updates for more details. Microsoft says addressing some of the Exchange vulnerabilities fixed this month requires administrators to enable Windows Extended protection on Exchange Servers. Microsoft also released fixes for three other Exchange flaws that rated a “critical” label, meaning they could be exploited remotely to compromise the system and with no help from users. The publicly disclosed Exchange flaw is CVE-2022-30134, which is an information disclosure weakness. Microsoft this month also issued a different patch for another MSDT flaw, tagged as CVE-2022-35743. This latest MSDT bug - CVE-2022-34713 - is a remote code execution flaw that requires convincing a target to open a booby-trapped file, such as an Office document. In June, Microsoft patched a vulnerability in MSDT dubbed “ Follina” that had been used in active attacks for at least three months prior. Redmond also addressed multiple flaws in Exchange Server - including one that was disclosed publicly prior to today - and it is urging organizations that use Exchange for email to update as soon as possible and to enable additional protections. Once again, Microsoft is patching a zero-day vulnerability in the Microsoft Support Diagnostics Tool (MSDT), a service built into Windows. ![]() ![]() Microsoft today released updates to fix a record 141 security vulnerabilities in its Windows operating systems and related software.
