1 known affected

The vendor explicitly identifies these products as affected by this CVE.

  • MConfig Version <=1.4.9.21
Summary
During the runtime of the MConfig Software application, an attacker can export the memory dump file into the operating system. If passwords are stored in plain text in memory, they will be included in these dump files. If such dump files are mishandled, attackers could obtain them and extract the passwords.
Remediation
The vulnerability is resolved in the following product versions: MConfig version 1.4.9.22 ABB advises users to update their devices to the latest software version. Additionally, ABB recommends implementing defensive measures to reduce the risk of vulnerability exploitation, as outlined in the product instruction manual.

What, why and how

Cleartext Storage of Sensitive Information in Memory vulnerability in ABB MConfig.This issue affects MConfig: through 1.4.9.21.

What

Cleartext Storage of Sensitive Information in Memory vulnerability in ABB MConfig.This issue affects MConfig: through 1.4.9.21.

Why

The product stores sensitive information in cleartext in memory.

How

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

What

Cleartext Storage of Sensitive Information in Memory vulnerability in ABB MConfig.This issue affects MConfig: through 1.4.9.21.

Why

The product stores sensitive information in cleartext in memory.

How

An attacker operating through local access 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
local access → Cleartext Storage of Sensitive Information in Memory → obtain information outside the intended access boundary
Attack surface
Local
Privileges required
Low: a basic authenticated account is required

CWE-316 ↗

CWE-316: Cleartext Storage of Sensitive Information in Memory. The product stores sensitive information in cleartext in memory.
