Detection & IOCsextracted from sources · hover to see the quote

  • Vulnerability is triggered via a crafted web page targeting Internet Explorer 11; the root cause is improper memory access in MSHTML's CMultiReadStreamLifetimeManager::ReleaseThreadStateInternal, resulting in a Read Access Violation
  • PoC exploit uses FileReader.readAsDataURL() on an empty Blob combined with garbage collection to trigger the memory corruption; monitor for unusual FileReader/Blob usage patterns in IE11 scripting contexts
  • The vulnerability involves the Microsoft Windows Text Services Framework object handling in memory; detection should focus on IE11 processes interacting with TSF objects leading to memory corruption
  • Exploit status rated 'Exploitation More Likely' for both latest and older software releases; prioritize detection on unpatched IE11 instances
  • ·The PoC triggers garbage collection explicitly as part of the exploit chain; CollectGarbage() is an IE-specific scripting function and its presence alongside FileReader/Blob operations may indicate exploit activity rather than legitimate use
