Detailsinfo

A vulnerability has been found in SICK LMS5xx (the affected version unknown) and classified as critical. Affected by this vulnerability is an unknown part. The manipulation with an unknown input leads to a channel accessible vulnerability. The CWE definition for the vulnerability is CWE-300. The product does not adequately verify the identity of actors at both ends of a communication channel, or does not adequately ensure the integrity of the channel, in a way that allows the channel to be accessed or influenced by an actor that is not an endpoint. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

A remote unprivileged attacker can intercept the communication via e.g. Man-In-The-Middle, due to the absence of Transport Layer Security (TLS) in the SICK LMS5xx. This lack of encryption in the communication channel can lead to the unauthorized disclosure of sensitive information. The attacker can exploit this weakness to eavesdrop on the communication between the LMS5xx and the Client, and potentially manipulate the data being transmitted.

The weakness was shared 08/25/2023 as sca-2023-0007. It is possible to read the advisory at sick.com. This vulnerability is known as CVE-2023-4420 since 08/18/2023. The technical details are unknown and an exploit is not publicly available. The pricing for an exploit might be around USD $0-$5k at the moment (estimation calculated on 09/20/2023). The attack technique deployed by this issue is T1557 according to MITRE ATT&CK.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
