CVE-2023-5392 describes an information leak vulnerability in Honeywell C300 products, where an analysis feature allows an attacker to extract more memory over the network than intended. This vulnerability carries a high CVSS score of 7.5, indicating a critical risk due to its network-based attack vector, low attack complexity, and high potential for confidentiality impact. While no active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion has been observed, Honeywell recommends updating to the latest product version to mitigate this risk.
