Microsoft Internet Explorer vulnerability
Microsoft Internet Explorer contains an ASLR bypass vulnerability allowing remote attackers to circumvent address space layout randomization protections through crafted websites.
Verdict
Today item — known-exploited.
A remote attacker can bypass ASLR protections in Internet Explorer by hosting a malicious website, reducing the effectiveness of memory-based exploit mitigations and increasing the likelihood of successful code execution attacks.
01
Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
3 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 0.33581 — 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 leak memory layout information or predict ASLR offsets in Internet Explorer.
Business
The organization's endpoint defense strategy is weakened as ASLR, a critical memory protection mechanism, becomes unreliable.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I trick a user into visiting my website through social engineering or drive-by compromise.
Business
User systems become vulnerable to follow-on exploitation attacks that were previously mitigated by ASLR.
3
Lateral reach — past segmentation narrative 3
Attacker
I combine this ASLR bypass with other memory corruption vulnerabilities to achieve reliable remote code execution.
Business
Attackers gain the ability to execute arbitrary code and establish persistent compromise on affected systems.
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.
