T1203 Exploitation for Client Execution
T1559.002 Component Object Model and Distributed Component Object Model
The critical heuristic firing for CVE_2017_11882_EQUATION_OLE10NATIVE indicates the exploitation of a known vulnerability in Microsoft Equation Editor. This technique is commonly used to execute arbitrary code, likely to download and run a secondary payload. The presence of an OLE object further supports this attack vector.
Heuristics 2
-
Equation Editor Ole10Native payload — CVE-2017-11882 critical CVE likely CVE_2017_11882_EQUATION_OLE10NATIVEAn embedded Microsoft Equation 3.0 object (CLSID 0002CE02-0000-0000-C000-000000000046) carries an Ole10Native packager stream instead of the normal Equation Native/MTEF data. This is the weaponized Equation Editor RCE delivery shape used by CVE-2017-11882 / CVE-2018-0802 maldocs. The payload (font-record overflow + shellcode) is frequently encrypted and the stream name case-scrambled to evade scanners, but an Equation object holding an Ole10Native stream has no benign use.
-
Equation Editor OLE object high OLE_EQUATION_EDITORContains Equation Editor object — related to CVE-2017-11882 / CVE-2018-0802 exploitation, but CLSID presence alone is not the malformed MTEF exploit primitive.
