  • SICK SOPAS Engineering Tool <2021.4 (4.8.0)
Summary
SDD files might contain an executable file that will be listed as the Emulators inside SOPAS ET. When a user starts the emulator, the executable is run without further checks. Attackers could wrap any executable file into an SDD and provide this to a SOPAS ET user. When installing the SDD the user may not be aware about the executable inside of the SDD.
Remediation
Update to at least version 4.8.0

01

What, why and how

SICK SOPAS ET before version 4.8.0 allows attackers to wrap any executable file into an SDD and provide this to a SOPAS ET user. When a user starts the emulator the executable is run without further checks.

What

SICK SOPAS ET before version 4.8.0 allows attackers to wrap any executable file into an SDD and provide this to a SOPAS ET user. When a user starts the emulator the executable is run without further checks.

Why

The current structured CVE record identifies a security weakness, but the root cause requires confirmation in the linked vendor material.

How

An attacker operating through local access may attempt exploitation without authentication after a user interaction. 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

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

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

AVLocalAttack vector: The attacker needs local access to the vulnerable system.ACLowAttack complexity: No specialised conditions are required beyond attacker-controlled input.PRNonePrivileges required: The attacker does not need an account or existing privileges.UIRequiredUser interaction: Another user must perform an action for exploitation to succeed.SChangedScope: The attack can affect a component governed by a different security 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
The issue can support a local privilege or sandbox boundary transition; normal system utilities may then be available in the gained context.
