Microsoft is urging users to patch a zero-day vulnerability dubbed Dogwalk that is actively being exploited in the wild.
The warning is part of a massive August Patch Tuesday update that included flaws, 17 of which were critical and carrying a Common Vulnerability Scoring System rating of Important. The actively exploited Dogwalk bug was first reported to Microsoft in January by researcher Imre Rad. Microsoft scored the vulnerability as Important and warns that the exploitation of the bug can only be preformed by an adversary with physical access to a vulnerable computer.
However, researchers at Zero Day Initiative outline how a remote attack might occur. Microsoft describes a possible attack as having a low complexity value, meaning it can be exploited easily and requires no advance system privileges to execute. The most serious of the vulnerabilities patched on Tuesday include a trio of elevation of privilege vulnerabilities opening instances of Microsoft Exchange Server to attack.
Microsoft has released a separate alert page for this flaw to help mitigate the flaws. Rated between 8. This is the fourth month in a row that Microsoft has deployed a critical NFS code execution patch. Interestingly, Microsoft describes the flaw as Important, while researchers warn the bug is Critical and should be a priority patch. This would provide the threat actor with code execution at elevated privileges.
Separate fixes to macOS and iOS patch respective flaws in the kernel and WebKit that can allow threat actors to take over devices and are under attack. An insufficient validation input flaw, one of 11 patched in an update this week, could allow for arbitrary code execution and is under active attack. This site uses Akismet to reduce spam.
