Summary
Multiple vulnerabilities in SICK MEAC300

Notes

summary
SICK has identified vulnerabilities in MEAC300. These vulnerabilities, related to the OpenSSL library and specific device functionalities, could potentially allow remote, unauthenticated attackers to: 1) Cause a denial of service: Triggering an infinite loop that consumes CPU resources, rendering the device unresponsive (CVE-2022-0778). This impacts MEAC300 DE devices running vulnerable OpenSSL versions when processing manipulated SSH certificates. 2) Compromise the MEAC300: Exploit vulnerabilities accessible via Ethernet to potentially impact the availability, integrity, and confidentiality of the device. SICK recommends ensuring that affected products operate within secure network environments to mitigate these risks.
General Security Measures
As general security measures, SICK recommends to minimize network exposure of the devices, restrict network access and follow recommended security practices in order to run the devices in a protected IT environment.
Vulnerability Classification
SICK performs vulnerability classification by using the CVSS scoring system (*CVSS v3.1*). The environmental score is dependent on the customer’s environment and can affect the overall CVSS score. SICK recommends that customers individually evaluate the environmental score to achieve final scoring.

Internally this function is used when parsing certificates that contain elliptic curve public keys in compressed form or explicit elliptic curve parameters with a base point encoded in compressed form. It is possible to trigger the infinite loop by crafting a certificate that has invalid explicit curve parameters. Since certificate parsing happens prior to verification of the certificate signature, any process that parses an externally supplied certificate may thus be subject to a denial-of-service attack. The infinite loop can also be reached when parsing crafted private keys as they can contain explicit elliptic curve parameters.\u201d",
