2 known affected

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

  • ABB M2M Gateway ARM600, firmware versions >=4.1.2|<=5.0.3
  • ABB M2M Gateway SW, software versions >=5.0.1|<=5.0.3
Summary
Processing large delegations may severely degrade resolver performance effectively denying legitimate clients access to the DNS resolution service. This could cause a denial-of-service conditions.
Remediation
Mitigating factors describe conditions and circumstances that make an attack that exploits the vulnerability difficult or less likely to succeed. The following mitigations are recommended. 3. ARM600 system is by default not dependent on the name service (DNS). If name service is not used in the system, the name service port (TCP/UDP port 53) can be blocked by a firewall. Refer to section General security recommendations for additional advice on how to keep your system secure.

01

What, why and how

By flooding the target resolver with queries exploiting this flaw an attacker can significantly impair the resolver's performance, effectively denying legitimate clients access to the DNS resolution service.

What

By flooding the target resolver with queries exploiting this flaw an attacker can significantly impair the resolver's performance, effectively denying legitimate clients access to the DNS resolution service.

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 a network path may attempt exploitation without authentication or 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
a network path → vulnerable operation → cause the confidentiality, integrity or availability impact described by the vendor
