Microsoft Internet Explorer vulnerability
Use-after-free vulnerability in Microsoft Internet Explorer enables remote code execution. Actively exploited in the wild with high severity.
Verdict
Today item — known-exploited.
A use-after-free flaw in Internet Explorer allows attackers to achieve remote code execution by crafting malicious web content. The vulnerability has been observed in active exploitation campaigns, presenting significant risk to users accessing untrusted websites.
01
Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
12 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 2022-05-04).
Probability (EPSS)
EPSS 0.85239 — 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-416 Use After Free — weakness family: Memory safety.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 that triggers improper memory handling in Internet Explorer's rendering engine.
Business
Users visiting compromised or attacker-controlled websites face immediate risk of system compromise and data theft.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I exploit the use-after-free condition to execute arbitrary code with the privileges of the browser process.
Business
Attackers gain foothold for lateral movement, credential harvesting, and deployment of secondary malware payloads.
3
Lateral reach — past segmentation narrative 3
Attacker
I establish persistence and exfiltrate sensitive information from the compromised system.
Business
Organizations face data breaches, intellectual property theft, and operational disruption from widespread browser-based attacks.
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.
