Microsoft Internet Explorer vulnerability
Internet Explorer use-after-free vulnerability in CDwnBindInfo object handling allows remote code execution via crafted websites.
Verdict
Today item — known-exploited.
A use-after-free flaw in Internet Explorer enables remote attackers to execute arbitrary code by crafting malicious web content that triggers access to improperly allocated or freed objects, posing direct execution risk to users.
01
Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
13 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 2024-07-23).
Probability (EPSS)
EPSS 0.78823 — 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 web page containing JavaScript or HTML that triggers improper object lifecycle handling in Internet Explorer's CDwnBindInfo component.
Business
Users visiting attacker-controlled or compromised websites face immediate code execution risk without additional user interaction beyond normal browsing.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I host the exploit on a website and distribute the link through email, forums, or advertisements to maximize exposure among Internet Explorer users.
Business
Attack surface spans any user accessing the malicious content, creating broad infection potential across customer base and supply chain partners.
3
Lateral reach — past segmentation narrative 3
Attacker
I execute arbitrary code with the privileges of the logged-in user, enabling data theft, lateral movement, or system compromise.
Business
Compromised systems may leak sensitive data, become vectors for further network intrusion, or suffer operational disruption from malware installation.
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.
