Microsoft Warning - Windows Flaw Being Attacked
Microsoft security experts have discovered zero-day exploits of a key flaw in its flagship Windows platform and issued a warning saying that its security teams had detected zero-day exploitation of a critical vulnerability that had been previously disclosed. Microsoft released the bulletin telling users to be careful about potential attacks.
The problem lies in the Windows platform and was fixed in the latest batch of Patch Tuesday updates, however, attackers are actively exploiting the flaw to gain system privileges on unpatched Windows machines.
“An attacker who successfully exploited this vulnerability could gain system privileges. An attacker must already have access and the ability to run code on the target system... This technique does not allow for remote code execution in cases where the attacker does not already have that ability on the target system,” says Microsoft.
The vulnerability was allegedly reported to Microsoft by four different organisations, suggesting that it was likely used as an exploit chain. No technical details regarding the bug have been released, as it is possible this could help attackers to continue to exploit it. In addition, no indicators of compromise were identified.
The vulnerability can be exploited by an attacker using social engineering or phishing tactics to trick a user into opening a malicious document or file or visiting a compromised website to the same end.
The flaw has a CVSS score of 7.8 out of 10. The latest patch Tuesday covered 64 new vulnerabilities that exist in a range of Windows and OS components, such as SharePoint, Office, Defender, and Microsoft Edge. In addition to Microsoft, software maker Adobe also put out security solutions for at least 63 security vulnerabilities in a wide range of widely deployed Windows and macOS software products
As part of the scheduled September batch of Patch Tuesday updates, Adobe called attention to critical-rated bulletins affecting the Adobe Bridge, InDesign, Photoshop, InCopy, Animage and Illustrator software products. Adobe said it was not aware of any exploits in the wild for any of the patched vulnerabilities.
