1 known affected

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

  • RUGGEDCOM RST2428P (6GK6242-6PA00)
Summary
The affected device may be susceptible to resource exhaustion when subjected to high volumes of query requests. This could allow an attacker to cause a temporary denial of service, with the system recovering once the activity stops.
Remediation
Create a firewall rule that blocks the UDP ports if not required. The device uses UDP 34964 and one port in range 49152-65535 for discovery protocols like LLDP, DCP, MRP etc.

01

What, why and how

A vulnerability has been identified in RUGGEDCOM RST2428P (6GK6242-6PA00) (All versions). The affected device may be susceptible to resource exhaustion when subjected to high volumes of query requests. This could allow an attacker to cause a temporary denial of service, with the system recovering once the activity stops.

What

A vulnerability has been identified in RUGGEDCOM RST2428P (6GK6242-6PA00) (All versions). The affected device may be susceptible to resource exhaustion when subjected to high volumes of query requests. This could allow an attacker to cause a temporary denial of service, with the system recovering once the activity stops.

Why

The product does not properly control the allocation and maintenance of a limited resource.

How

An attacker operating through an adjacent network may attempt exploitation without authentication or user interaction. If successful, the issue may disrupt the affected service.

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 → Uncontrolled Resource Consumption → disrupt the affected service
Attack surface
Adjacent
Privileges required
None: unauthenticated exploitation is possible
User interaction
None
Attack complexity
High: exploitation depends on specific conditions
Security boundary

Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-400 ↗

CWE-400: Uncontrolled Resource Consumption. The product does not properly control the allocation and maintenance of a limited resource.

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

De kwetsbaarheden stellen een kwaadwillende mogelijk in staat aanvallen uit te voeren die kunnen leiden tot de volgende categorieën schade: - Denial-of-Service (DoS) - Manipulatie van gegevens - Omzeilen van een beveiligingsmaatregel - (Remote) code execution (root/admin rechten) - Toegang tot systeemgegevens - Toegang tot gevoelige gegevens - Verhogen van rechten De kwaadwillende heeft hiervoor toegang nodig tot de productieomgeving. Het is goed gebruik een dergelijke omgeving niet publiek toegankelijk te hebben.
