Microsoft Internet Explorer vulnerability
Microsoft Internet Explorer contains an unspecified vulnerability allowing remote attackers to gain elevated privileges through a crafted website.
Verdict
Today item — known-exploited.
A privilege escalation vulnerability in Internet Explorer enables remote code execution when users visit malicious websites. The vulnerability has been observed in active exploitation 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 2022-05-25).
Probability (EPSS)
EPSS 0.26349 — 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-264 Permissions/Privileges/Access Control — 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 vulnerability when visited by Internet Explorer users.
Business
Users visiting untrusted or compromised websites face immediate risk of system compromise.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I exploit the vulnerability to escape the browser sandbox and gain elevated system privileges.
Business
Attackers obtain administrative or system-level access, enabling full system control and data exfiltration.
3
Lateral reach — past segmentation narrative 3
Attacker
I use elevated privileges to install malware, steal credentials, or establish persistent access.
Business
Organizations experience data breaches, credential compromise, and potential lateral movement across 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.
