01

What, why and how

The App Settings (/admin/app) page in GROWI versions prior to v6.0.6 stores sensitive information in cleartext form. As a result, the Secret access key for external service may be obtained by an attacker who can access the App Settings page.

What

The App Settings (/admin/app) page in GROWI versions prior to v6.0.6 stores sensitive information in cleartext form. As a result, the Secret access key for external service may be obtained by an attacker who can access the App Settings page.

Why

The product stores sensitive information in cleartext within a resource that might be accessible to another control sphere.

How

An attacker operating through a network path may attempt exploitation with low privileges. If successful, the issue may obtain information outside the intended access boundary.

What

The App Settings (/admin/app) page in GROWI versions prior to v6.0.6 stores sensitive information in cleartext form. As a result, the Secret access key for external service may be obtained by an attacker who can access the App Settings page.

Why

The product stores sensitive information in cleartext within a resource that might be accessible to another control sphere.

How

An attacker operating through a network path may attempt exploitation with low privileges. If successful, the issue may obtain information outside the intended access boundary.

02

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 → Cleartext Storage of Sensitive Information → obtain information outside the intended access boundary

CWE-312 ↗

CWE-312: Cleartext Storage of Sensitive Information. The product stores sensitive information in cleartext within a resource that might be accessible to another control sphere.

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:L/UI:N/S:U/C:H/I:N/A:N

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.PRLowPrivileges required: The attacker needs basic user-level 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.INoneIntegrity impact: No direct loss is represented by this metric.ANoneAvailability impact: No direct loss is represented by this metric.
Post-exploitation / living off the land
No specific living-off-the-land technique is confirmed in the structured sources. Monitor normal administration tools for activity inconsistent with the affected service's baseline.
