Microsoft Office vulnerability
Stack-based buffer overflow in Microsoft Office RTF parsing allows remote code execution. Actively exploited in the wild.
Verdict
Today item — known-exploited.
A stack buffer overflow in RTF document handling enables unauthenticated remote code execution when a user opens a malicious document. High EPSS score and confirmed wild exploitation indicate immediate risk to Office users.
01
Is it exploitable?
— the evidence, ranked above the scoreExploit available
Public proof-of-concept exploit code is cataloged for this vulnerability.We link the existence of the exploit; we do not host or redistribute payloads.
Reported exploitation
25 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 0.89497 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Microsoft, Office. 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
Craft a malicious RTF file with oversized data fields to overflow the stack buffer during parsing.
Business
Users opening email attachments or downloaded documents face immediate system compromise and data theft.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
Trigger code execution with attacker-controlled payload written to the stack during RTF processing.
Business
Attackers gain full system access, enabling lateral movement, credential harvesting, and persistent presence in enterprise networks.
3
Lateral reach — past segmentation narrative 3
Attacker
Distribute the malicious RTF via email or web downloads to maximize infection surface.
Business
Organizations face widespread endpoint compromise, operational disruption, and potential regulatory violations from data exposure.
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.
