Microsoft Internet Explorer vulnerability
A use-after-free vulnerability in Internet Explorer's CDisplayPointer component allows remote code execution when a user visits a malicious webpage.
Verdict
Today item — known-exploited.
This vulnerability enables unauthenticated remote attackers to execute arbitrary code with user privileges through specially crafted web content. Active exploitation in the wild demonstrates immediate risk to unpatched systems.
01
Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
5 independent public reports of in-the-wild exploitation are cataloged.Distinct reporting sources (vendor, incident response, government); open them for the underlying claims.
Exploited in the wild
Listed in the CISA Known Exploited Vulnerabilities catalog (added 2022-03-03).
Probability (EPSS)
EPSS 0.77462 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Microsoft, Internet Explorer. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-399 Resource Management Errors — weakness family: Resource / availability.CWE assignment from the public NVD record; the weakness class drives how the flaw is exploited.
02
Who’s exploiting it?
— attribution turns risk into urgencyAttribution not established
No confirmed (advisory-backed) threat-actor attribution is established for this record. Absence of a named actor is not absence of compromise — see Coverage & confidence.
03
Why it matters
— the attack path, told twice: adversary, then board1
Front door — unauthenticated access narrative 1
Attacker
I craft a malicious webpage containing code that triggers the use-after-free condition in CDisplayPointer.
Business
Users visiting the attacker's site or compromised legitimate sites face immediate code execution risk.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I host the exploit on a website or distribute it through drive-by download attacks.
Business
Attack surface expands across the web, affecting any user with vulnerable Internet Explorer versions.
3
Lateral reach — past segmentation narrative 3
Attacker
I gain code execution in the browser context with the privileges of the logged-in user.
Business
Attackers can steal credentials, install malware, access sensitive data, or pivot to internal networks.
04
What to do
— defensible action- Remediate per the vendor advisory — confirm the fixed build for your version and verify exposure.1
Say it to the boardA vulnerability with this evidence profile is a defensible budget line, not a backlog ticket — fund the change against the proof above.
