What, why and how

Cleartext Transmission of Sensitive Information vulnerability in ABB Terra AC wallbox (UL40/80A), ABB Terra AC wallbox (UL32A), ABB Terra AC wallbox (CE) (Terra AC MID), ABB Terra AC wallbox (CE) Terra AC Juno CE, ABB Terra AC wallbox (CE) Terra AC PTB, ABB Terra AC wallbox (CE) Symbiosis, ABB Terra AC wallbox (JP).This issue affects Terra AC wallbox (UL40/80A): from 1.0;0 through 1.5.5; Terra AC wallbox (UL32A) : from 1.0;0 through 1.6.5; Terra AC wallbox (CE) (Terra AC MID): from 1.0;0 through 1.6.5; Terra AC wallbox (CE) Terra AC Juno CE: from 1.0;0 through 1.6.5; Terra AC wallbox (CE) Terra AC PTB : from 1.0;0 through 1.5.25; Terra AC wallbox (CE) Symbiosis: from 1.0;0 through 1.2.7; Terra AC wallbox (JP): from 1.0;0 through 1.6.5.

What

Why

The product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors.

How

An attacker operating through an adjacent network may attempt exploitation without authentication after a user interaction. If successful, the issue may obtain information outside the intended access boundary.

What

Why

The product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors.

How

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: an adjacent network → Cleartext Transmission of Sensitive Information → obtain information outside the intended access boundary
Attack surface: Adjacent
Privileges required: None: unauthenticated exploitation is possible
User interaction: Required interaction required
Attack complexity: High: exploitation depends on specific conditions
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-319 ↗
CWE-319: Cleartext Transmission of Sensitive Information. The product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors.
CVSS vector ? CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.: CVSS:3.1/AV:A/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H
Common Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.
AVAdjacentAttack vector: The attacker must be on an adjacent or logically close network.ACHighAttack complexity: Successful exploitation depends on specific conditions outside the attacker's direct control.PRNonePrivileges required: The attacker does not need an account or existing privileges.UIRequiredUser interaction: Another user must perform an action for exploitation to succeed.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: 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.
