Detection & IOCsextracted from sources · hover to see the quote

  • Vulnerable driver targeted by the exploit is cldflt.sys (Windows Cloud Files Mini Filter Driver); monitor for suspicious interactions with this driver, especially heap overflow attempts leading to SYSTEM privilege escalation
  • Exploitation results in SYSTEM privileges; monitor for unexpected SYSTEM-level process creation originating from lower-privileged user-mode processes, particularly those interacting with cldflt.sys
  • Metasploit module exists for this CVE (exploits/windows/local/cve_2024_30085_cloud_files); presence of this module or its artifacts on a host is a strong indicator of exploitation attempt
  • ·Affected scope is limited to specific Windows versions; exploitation is only relevant on workstation versions 10_1809 through 11_23H2 and server versions 2022 to 22_23H2
  • ·As of the MSRC advisory, this vulnerability had not been observed exploited in the wild, but was rated 'Exploitation More Likely'
