01

What, why and how

Use of a Broken or Risky Cryptographic Algorithm in SICK RFU62x firmware version < 2.21 allows a low-privileged remote attacker to decrypt the encrypted data if the user requested weak cipher suites to be used for encryption via the SSH interface. The patch and installation procedure for the firmware update is available from the responsible SICK customer contact person.

What

Use of a Broken or Risky Cryptographic Algorithm in SICK RFU62x firmware version < 2.21 allows a low-privileged remote attacker to decrypt the encrypted data if the user requested weak cipher suites to be used for encryption via the SSH interface. The patch and installation procedure for the firmware update is available from the responsible SICK customer contact person.

Why

The product uses a broken or risky cryptographic algorithm or protocol.

How

An attacker operating through a network path may attempt exploitation with low privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

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.
