Adjacent-network deserialization requiring no auth or interaction maps to AV:A/AC:L/PR:N/UI:N; full host compromise gives C:H/I:H/A:H with no scope change (S:U).

Deserialization of untrusted data vulnerability in Johnson Control victor on Windows allows capec-586.
This issue affects victor: from 2.9 before 3.0.
AnalysisAI
Deserialization of untrusted data in Johnson Controls victor video management software (versions 2.9 up to but not including 3.0) on Windows allows an adjacent-network attacker to trigger object injection (CAPEC-586) and achieve high impact on confidentiality, integrity, and availability. The CVSS 4.0 vector (AV:A/PR:N/UI:N) indicates unauthenticated exploitation is possible for an attacker positioned on the same local network segment, with no user interaction. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to be on the same adjacent network segment as the victor host (CVSS AV:A) - not the open internet - and to be able to deliver a crafted serialized payload to a victor component that deserializes untrusted data (CWE-502/CAPEC-586); the affected software must be victor version 2.9 through any release before 3.0 running on Windows. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor-supplied CVSS 4.0 score of 8.7 (High) reflects an adjacent-network attack vector (AV:A), low complexity (AC:L), no privileges (PR:N), no user interaction (UI:N), and high impact to confidentiality, integrity, and availability (VC:H/VI:H/VA:H) with no scope change to subsequent systems. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who gains a foothold on the same local network segment as a victor host (for example a compromised workstation, camera, or rogue device on the security VLAN) sends a crafted serialized object to a victor service that deserializes it without validation. The malicious object graph is deserialized and triggers object injection, granting the attacker high-impact control over the victor host without any credentials or user interaction. … |
| Remediation | Upgrade Johnson Controls victor to version 3.0 or later, which is the first release outside the affected range (from 2.9 before 3.0) and remediates the deserialization flaw; consult the Johnson Controls advisory at https://www.johnsoncontrols.com/trust-center/cybersecurity/security-advisories for the exact patched build and upgrade guidance. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all systems running Johnson Controls victor versions 2.9 and restrict network access to video management interfaces through firewall rules or VLAN isolation to limit exposure to adjacent-network attackers only. …
