What, why and how

A buffer underwrite ('buffer underflow') vulnerability in the administrative interface of Fortinet FortiOS version 7.2.0 through 7.2.3, version 7.0.0 through 7.0.6, version 6.4.0 through 6.4.11 and version 6.2.12 and below, FortiProxy version 7.2.0 through 7.2.2, version 7.0.0 through 7.0.8, version 2.0.12 and below and FortiOS-6K7K version 7.0.5, version 6.4.0 through 6.4.10 and version 6.2.0 through 6.2.10 and below allows a remote unauthenticated attacker to execute arbitrary code or commands via specifically crafted requests.

A buffer underwrite ('buffer underflow') vulnerability in the administrative interface of Fortinet FortiOS version 7.2.0 through 7.2.3, version 7.0.0 through 7.0.6, version 6.4.0 through 6.4.11 and version 6.2.12 and below, FortiProxy version 7.2.0 through 7.2.2, version 7.0.0 through 7.0.8, version 2.0.12 and below and FortiOS-6K7K version 7.0.5, version 6.4.0 through 6.4.10 and version 6.2.0 through 6.2.10 and below allows a remote unauthenticated attacker to execute arbitrary code or commands via specifically crafted requests.

Why

The product writes to a buffer using an index or pointer that references a memory location prior to the beginning of the buffer.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may execute code or commands in the affected security context.

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 → Buffer Underwrite ('Buffer Underflow') → execute code or commands in the affected security context
Attack surface
Network
Privileges required
None: unauthenticated exploitation is possible
User interaction
None
Attack complexity
Low: no specialised conditions are recorded
Security boundary
Unchanged: impact remains within the vulnerable component's security authority
Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-124 ↗

CWE-124: Buffer Underwrite ('Buffer Underflow'). The product writes to a buffer using an index or pointer that references a memory location prior to the beginning of the buffer.

CVSS vector
?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:P/RL:U/RC:C

Common Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.

AVNetworkAttack vector: The vulnerable component can be reached over a network.ACLowAttack complexity: No specialised conditions are required beyond attacker-controlled input.PRNonePrivileges required: The attacker does not need an account or existing privileges.UINoneUser interaction: No action by another user is required.SUnchangedScope: The security impact remains within the vulnerable component's authority.CHighConfidentiality impact: A successful attack can cause a major loss.IHighIntegrity impact: A successful attack can cause a major loss.AHighAvailability impact: A successful attack can cause a major loss.
Post-exploitation / living off the land
After compromise, an attacker may use built-in shells, scripting engines, scheduled tasks and native network utilities for discovery, persistence or movement. This is a plausible LoTL path, not evidence that it has occurred for every attack.
