Microsoft Internet Explorer vulnerability
Microsoft Internet Explorer information disclosure vulnerability allows remote attackers to obtain sensitive data from process memory through a crafted website.
Verdict
Today item — known-exploited.
A remote, unauthenticated attacker can craft a malicious website that, when visited by an Internet Explorer user, extracts sensitive information from the browser process memory. This vulnerability has been exploited in the wild.
01
Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
2 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 2022-03-28).
Probability (EPSS)
EPSS 0.61968 — 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-200 Information Exposure — weakness family: Authorization / access control.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 website designed to trigger the memory disclosure flaw in Internet Explorer.
Business
User browsing habits and website visits become vectors for targeted attacks.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I host the website and wait for victims to visit it through normal browsing or social engineering.
Business
Attackers gain access to sensitive data without requiring user interaction beyond visiting a page.
3
Lateral reach — past segmentation narrative 3
Attacker
I extract sensitive information from the Internet Explorer process memory, such as authentication tokens or cached credentials.
Business
Confidential user data and organizational secrets are compromised, enabling further 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.
