HIGHCVSS 7.4/10EPSS 0.24%

Last modified

CVE-2023-4420 is a high-severity vulnerability rated 7.4/10 on the CVSS scale. 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. EPSS estimates a 0.24% chance of exploitation in the next 30 days.

Description

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.
