Adobe Flash Player vulnerability
Memory corruption vulnerability in Adobe Flash Player enabling remote code execution. Actively exploited in the wild.
Verdict
Today item — known-exploited.
Out-of-bounds write flaw (CWE-787) in Flash Player permits unauthenticated attackers to execute arbitrary code through crafted content. High exploitation prevalence documented.
01
Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
10 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 0.7983 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Adobe, Flash Player. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-787 Out-of-bounds Write — 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 malicious Flash content triggering memory corruption during parsing or rendering.
Business
End-user systems compromised through legitimate web browsing or email attachment vectors.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
Achieve code execution within the Flash Player process context on the victim host.
Business
Attackers gain foothold for lateral movement, data exfiltration, or persistent compromise.
3
Lateral reach — past segmentation narrative 3
Attacker
Escalate privileges or pivot to system-level access depending on browser sandbox effectiveness.
Business
Enterprise security posture degraded; incident response and remediation costs incurred.
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.
