What, why and how

An out-of-bounds read vulnerability [CWE-125] in FortiOS SSLVPN web portal versions 7.4.0 through 7.4.4, versions 7.2.0 through 7.2.8, 7.0 all verisons, and 6.4 all versions may allow an authenticated attacker to perform a denial of service on the SSLVPN web portal via a specially crafted URL.

What

An out-of-bounds read vulnerability [CWE-125] in FortiOS SSLVPN web portal versions 7.4.0 through 7.4.4, versions 7.2.0 through 7.2.8, 7.0 all verisons, and 6.4 all versions may allow an authenticated attacker to perform a denial of service on the SSLVPN web portal via a specially crafted URL.

Why

The product reads data past the end, or before the beginning, of the intended buffer.

How

An attacker operating through a network path may attempt exploitation with low privileges. If successful, the issue may disrupt the affected service.

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

CWE-125 ↗

CWE-125: Out-of-bounds Read. The product reads data past the end, or before the beginning, of the intended buffer.

De kwetsbaarheden omvatten onder andere hard-coded cryptografische sleutels, onjuiste verwerking van OS-commando's, en out-of-bounds schrijf- en leesfouten. Aanvallers kunnen deze kwetsbaarheden misbruiken om ongeautoriseerde toegang te verkrijgen, willekeurige code uit te voeren en Denial-of-Service-aanvallen te veroorzaken.
