What are the issues Microsoft fixed?
There are multiple vulnerabilities that needed fixing from the tech giant, including a zero-day vulnerability known as CVE-2023-28252 that was actively being exploited by hackers. This particular vulnerability would give a hacker full control over any system that is compromised.
Here is a full breakdown of all the fixes made:
- 45 Remote Code Execution Vulnerabilities (meaning an attacker could execute malicious code on a remote system)
- 20 Elevation of Privilege Vulnerabilities (meaning an attacker could gain higher privileges on a compromised system)
- 10 Information Disclosure Vulnerabilities (which could expose sensitive information)
- 9 Denial of Service Vulnerabilities that could cause denial of service, disrupting normal system operation
- 8 Security Feature Bypass Vulnerabilities, which could allow an attacker to bypass security measures
- 6 Spoofing Vulnerabilities, which could allow an attacker to impersonate a legitimate user
Microsoft also fixed 17 vulnerabilities found within Microsoft Edge, Office, Word and Publisher that could allow remote code execution by simply opening malicious documents. These kinds of attacks are typically pursued through phishing campaigns, which is why all Microsoft users should update their software right now.
