CVE-2022-41091 is a Windows zero-day vulnerability that allows attackers to bypass the “Mark of the Web” (MOTW) security feature. This feature was designed to prevent malicious code from running on a system by restricting the execution of files downloaded from the internet. MOTW appends a metadata tag to downloaded files that identify the source of the download, and if the file is from an untrusted source, Windows will block it from executing.
However, the CVE-2022-41091 vulnerability allows attackers to bypass the MOTW feature by using specially crafted file paths that trick Windows into thinking the file was downloaded from a trusted source.
The risk of not patching this vulnerability is significant. Attackers can create and distribute malicious files using phishing emails, social engineering tactics, or by compromising legitimate websites to download them to users' systems. Once downloaded, attackers can use this exploit to bypass the MOTW security feature and execute the malicious code, leading to a potential breach of sensitive data, system hijacking, and other forms of cyberattacks.
Microsoft released a patch for this vulnerability as part of its November 2022 Patch Tuesday updates. Windows users are advised to ensure that their systems are updated with the latest patches to prevent exploitation of this vulnerability. They should also avoid downloading files from untrusted sources or clicking on suspicious links to reduce the risk of downloading malicious files.
