Kentico Xperience vulnerability
Kentico Xperience contains an unsafe deserialization vulnerability (CWE-502) that allows unauthenticated attackers to execute arbitrary code by bypassing security header validation.
Verdict
Today item — known-exploited.
An unauthenticated remote attacker can exploit improper deserialization in Kentico Xperience to achieve code execution without authentication. The vulnerability has been actively exploited in the wild and carries a high exploitation probability.
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
86 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 2022-03-25).
Probability (EPSS)
EPSS 0.96031 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Kentico, Xperience. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-502 Deserialization of Untrusted Data — 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 object and send it to the vulnerable endpoint, bypassing security header checks.
Business
Attackers gain immediate unauthenticated code execution capability against exposed Kentico instances.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I execute arbitrary commands on the server with the privileges of the web application process.
Business
Complete compromise of the web server and potential lateral movement into internal infrastructure.
3
Lateral reach — past segmentation narrative 3
Attacker
I establish persistence and exfiltrate sensitive data or deploy additional malware.
Business
Data breach, operational disruption, and reputational damage from active exploitation in the wild.
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.
