CVE-2024-38202: Windows Update Stack Elevation of Privilege Vulnerability

Noroxi assessment

Priority: Monitor (action score 30/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 1.6% (FIRST EPSS); higher than 77% of all records.
  • Someone with local access to the system can trigger it. A low-privileged account is enough. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Summary Microsoft was notified that an elevation of privilege vulnerability exists in Windows Update, potentially enabling an attacker with basic user privileges to reintroduce previously mitigated vulnerabilities or circumvent some features of Virtualization Based Security (VBS). However, an attacker attempting to exploit this vulnerability requires additional interaction by a privileged user to be successful. Microsoft has developed a security update to mitigate this threat which was made available October 08, 2024 and is provided in the Security Updates table of this CVE for customers to download. Note: Depending on your version of Windows, additional steps may be required to update Windows Recovery Environment (WinRE) to be protected from this vulnerability. Please refer to the FAQ section for more information. Guidance for customers who cannot immediately implement the update is provided in the Recommended Actions section of this CVE to help reduce the risks associated with this vulnerability and to protect their systems. If there are any further updates regarding mitigations for this vulnerability, this CVE will be updated and customers will be notified. We highly encourage customers to subscribe to Security Update Guide notifications to receive an alert if an update occurs. Details A security researcher informed Microsoft of an elevation of privilege vulnerability in Windows Update potentially enabling an attacker with basic user privileges to reintroduce previously mitigated vulnerabilities or circumvent some features of VBS. For exploitation to succeed, an attacker must trick or convince an Administrator or a user with delegated permissions into performing a system restore which inadvertently triggers the vulnerability. Microsoft has developed a security update to mitigate this threat which was made available October 08, 2024 and is provided in the Security Updates table of this CVE for customers to download. Note: Depending on your version of Windows, additional steps may be required to update Windows Recovery Environment (WinRE) to be protected from this vulnerability. Please refer to the FAQ section for more information. Guidance for customers who cannot immediately implement the update is provided in the Recommended Actions section of this CVE to help reduce the risks associated with this vulnerability and to protect their systems.
