What, why and how

A improper privilege management in Fortinet FortiSandbox version 4.2.0 through 4.2.2, 4.0.0 through 4.0.2 and before 3.2.3 and FortiDeceptor version 4.1.0, 4.0.0 through 4.0.2 and before 3.3.3 allows a remote authenticated attacker to perform unauthorized API calls via crafted HTTP or HTTPS requests.

What

A improper privilege management in Fortinet FortiSandbox version 4.2.0 through 4.2.2, 4.0.0 through 4.0.2 and before 3.2.3 and FortiDeceptor version 4.1.0, 4.0.0 through 4.0.2 and before 3.3.3 allows a remote authenticated attacker to perform unauthorized API calls via crafted HTTP or HTTPS requests.

Why

The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.

How

An attacker operating through a network path may attempt exploitation with low privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
a network path → Improper Privilege Management → cause the confidentiality, integrity or availability impact described by the vendor

Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-269

CWE-269: Improper Privilege Management. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.

CVSS vector
?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.
