Both operating systems have flaws that can increase access to base attackers. On Tuesday, the world woke up not to one, but to two new vulnerabilities — one in Windows and one in Linux — that allow hackers from a single button in a vulnerable system to circumvent restrictions. Operating system security and access to sensitive resources. p>
Because operating systems and applications are so hard to hack, successful attacks these days usually require two or more security holes. The vulnerability allows an attacker to gain access to low-grade operating system resources, where they can execute code or read sensitive data. The second vulnerability increases code execution or file access to operating system resources that are saved for items such as password storage or other sensitive operations. Accordingly, the value of the so-called vulnerabilities of local franchises has increased in recent years. Windows
accidentally cracked a Windows vulnerability on Monday when a researcher noted that he believed a coding drop in Windows 11 beta was coming. The researcher found that the content of the Security Account Manager - the database that stores user accounts and user security descriptions on the local computer - was read by users by reading the system's limited scores.
Allows password-protected data with encryption, reveals passwords used to install Windows, and obtains computer keys for the Windows Data Protection API - which can be used to decrypt the keys. Private encryption can be used. - Create an account on the vulnerable device. The end result is that the local user can upgrade the scores to the system level, which is the highest level in Windows. "I don't know yet the full extent of the problem, but there's a lot that I shouldn't think should be a problem," said researcher Jonas Likegaard. "Only one person has no doubts about this, even for EOP to SYSTEM sandbox programs." Ads
yarh - For some reason the win11 SAM file is now being read to users. So if you enable shadow casting, you can read Sam's file like this: I don't know the full scope of this issue yet, but I think the issue is pretty big. pic.twitter.com/kl8gQ1FjFt- Jonas L (@jonasLyk) Jul 19, 2021
People who responded to Lykkegaard were quick to point out that this wasn't the regression behavior introduced in Windows 11, instead this was also this vulnerability It is in the latest version of Windows 10. The US Emergency Preparedness Team said here that the vulnerability exists when the Volume Shadow Copy Service - a feature of Windows that allows operating systems or applications to "signal". "Snapshots" of a whole disk without file system lock - wipe.
If a VSS shadow version of the system drive is available, it is an unauthorized user privileged These files can be used to achieve various effects, including:Extract And use the account password hash. Find out the original Windows password. Get DPAPI Computer Keys, which can be used to decrypt all private keys on your computer. Computer account, which can be used to attack Silver Tickets
Note that shadow versions of VSS may not be available on some configurations but just having a system drive larger than 128 GB in size then doing a Windows update or MSI install make sure that the shadow version VSS is generated automatically. To check if a VSS shadow version system is available, execute the following from a privileged command line: vssadmin menu shadows
Researcher Benjamin Delby explained here how to avoid this damage The following was used to get the password for other sensitive data :
Q: What can you do when you have #emulation and some read access to Windows system files like SYSTEM, SAM, and SECURITY? Answer: A place to increase han points, thank you jonasLyk for this access Default access Windows
