Microsoft PowerPoint vulnerability
Microsoft PowerPoint remote code execution vulnerability via crafted Office documents, enabling arbitrary code execution or denial of service through memory corruption.
Verdict
Today item — known-exploited.
A memory corruption flaw in PowerPoint allows attackers to execute arbitrary code or crash the application by delivering malicious Office documents. Active exploitation in the wild indicates immediate risk to users opening untrusted presentations.
01
Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
6 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 2022-03-03).
Probability (EPSS)
EPSS 0.38497 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Microsoft, PowerPoint. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-119 Memory Buffer Bounds Error — 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 Office document with specially formatted content designed to trigger memory corruption in PowerPoint's parsing engine.
Business
Users receive and open the document, potentially exposing systems to unauthorized code execution or service disruption.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I deliver the weaponized document via email, file sharing, or web download to target users.
Business
Widespread distribution increases attack surface across the organization, affecting multiple endpoints simultaneously.
3
Lateral reach — past segmentation narrative 3
Attacker
Upon opening, the vulnerability triggers memory corruption, allowing me to execute arbitrary code with the privileges of the PowerPoint process.
Business
Compromised systems enable lateral movement, data theft, or installation of persistent malware within the network.
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.
