CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2017-0149 is a high-severity Out-of-bounds Write (CWE-787) vulnerability in Microsoft Internet Explorer. Its CVSS base score is 8.8 (High).
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.
Microsoft Internet Explorer versions 9 through 11 are affected by a memory corruption vulnerability tracked as CVE-2017-0149 and assigned CWE-787. The flaw permits remote attackers to trigger arbitrary code execution or a denial of service condition when a user visits a specially crafted web site. It is distinct from the issues described in CVE-2017-0018 and CVE-2017-0037, and carries a CVSS 3.1 base score of 8.8 reflecting network attack vector, low complexity, no required privileges, and required user interaction.
An attacker can host or compromise a web site containing malicious content that exploits the memory corruption when rendered by a vulnerable IE instance. Successful exploitation grants the ability to execute arbitrary code in the context of the current user or to crash the browser, with confidentiality, integrity, and availability impacts all rated high.
Microsoft published an advisory for CVE-2017-0149 through its Security Response Center portal that addresses the issue and provides guidance for affected customers. No information on observed in-the-wild exploitation is supplied in the available references.
