Operationally, exploitation aligns with the MITRE ATT&CK technique Security Account Manager (T1003.002); ranked in the top 2% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
A remote code execution vulnerability exists in the way that the scripting engine handles objects in memory in Internet Explorer, tracked as CVE-2020-0968 and also known as the Scripting Engine Memory Corruption Vulnerability. It is distinct from CVE-2020-0970 and is associated with CWE-787. The issue received a CVSS 3.1 score of 7.5, reflecting network attack vector, high attack complexity, no required privileges, and required user interaction.
An attacker can exploit the flaw over the network by supplying specially crafted content that triggers memory corruption when processed by the scripting engine in Internet Explorer. Successful exploitation grants the ability to execute arbitrary code with the privileges of the current user, potentially leading to full confidentiality, integrity, and availability impacts on the affected system.
Microsoft security advisories at the referenced MSRC portal provide official guidance and patches for the vulnerability. The CISA Known Exploited Vulnerabilities catalog entry confirms that the issue has been observed in active exploitation, underscoring the need for prompt application of available updates.
