01

What, why and how

Incorrect Default Permission vulnerability exists in SoMove (V2.8.1) and prior which could cause elevation of privilege and provide full access control to local system users to SoMove component and services when a SoMove installer script is launched.

What

Incorrect Default Permission vulnerability exists in SoMove (V2.8.1) and prior which could cause elevation of privilege and provide full access control to local system users to SoMove component and services when a SoMove installer script is launched.

Why

During installation, installed file permissions are set to allow anyone to modify those files.

How

An attacker operating through local access may attempt exploitation with low privileges. If successful, the issue may gain additional privileges.

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.

CWE-276: Incorrect Default Permissions. During installation, installed file permissions are set to allow anyone to modify those files.

Post-exploitation / living off the land
The issue can support a local privilege or sandbox boundary transition; normal system utilities may then be available in the gained context.
