IBM WebSphere Application Server and Hypervisor Edition vulnerability
Serialized-object deserialization vulnerability in IBM WebSphere Application Server allows remote attackers to execute arbitrary commands without authentication.
Verdict
Today item — known-exploited.
CWE-94 unsafe deserialization flaw enables unauthenticated remote code execution. Active exploitation in the wild with high EPSS score indicates immediate threat to exposed instances.
01
Is it exploitable?
— the evidence, ranked above the scoreExploit available
Fully weaponized — public exploit code is cataloged for this vulnerability.We link the existence of the exploit; we do not host or redistribute payloads.
Reported 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 2022-01-10).
Probability (EPSS)
EPSS 0.97655 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: IBM, WebSphere Application Server and Server Hypervisor Edition. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-94 Code Injection — weakness family: Injection.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 serialized Java object and send it to the vulnerable WebSphere endpoint.
Business
Attacker gains code execution within the application server process, compromising confidentiality, integrity, and availability of hosted applications and data.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I escalate from application context to system-level access by leveraging server privileges.
Business
Full infrastructure compromise becomes possible, including lateral movement to other systems and persistent backdoor 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.
