Dassault Systèmes DELMIA Apriso vulnerability
Dassault Systèmes DELMIA Apriso contains a deserialization of untrusted data vulnerability (CWE-502) enabling remote code execution. The vulnerability is actively exploited in the wild.
Verdict
Today item — known-exploited.
An unauthenticated or low-privileged attacker can exploit unsafe deserialization in DELMIA Apriso to execute arbitrary code remotely, potentially compromising manufacturing operations and sensitive production data.

Severity / affected
CVSS 9 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H) · Affected: Dassault Systèmes, DELMIA Apriso. Confirm exact fixed builds in the vendor advisory.CVSS — CNA-assigned (CVE.org), version 3.1, set at disclosure.
Weakness (CWE)
Mapped to CWE-502 Deserialization of Untrusted Data — weakness family: Injection.CWE — CNA-assigned (CVE.org); the weakness class drives how the flaw is exploited.
CISA SSVC (triage disposition)
Exploitation: active · Automatable: no · Technical Impact: totalCISA's own stakeholder-specific triage inputs, published in the CVE record (CISA Coordinator role). NOTE: this is CISA's three decision points; the final Act/Attend/Track decision also requires a Mission & Well-being input not published here, so no overall decision is asserted.
Currency of the record
CISA added this to its KEV catalog 101 days after the CVE record was published.KEV lag = CISA-KEV dateAdded − CVE.org datePublished; a floor on how long the known-exploited flaw sat in the public record before the federal catalog listed it. Severity/weakness here is CNA- or CISA-assigned (current at disclosure), independent of NVD's analysis backlog.

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 deserialization endpoint in DELMIA Apriso.
Business
Manufacturing operations face immediate risk of system compromise and data theft.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
Upon deserialization, my payload executes arbitrary code with the privileges of the application process.
Business
Attackers gain persistent access to production systems and can modify or exfiltrate manufacturing data.
3
Lateral reach — past segmentation narrative 3
Attacker
I establish command and control over the compromised system to maintain access and pivot to connected infrastructure.
Business
Supply chain integrity is compromised; competitors or malicious actors gain visibility into proprietary designs and processes.
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.
