Summary

CVE-2023-37551 is a vulnerability that affects multiple versions of Codesys products. After successful authentication, specially crafted network communication requests can be used to download files with any file extensions to the controller using the CmpApp component. Unlike regular file downloads, no filtering of certain file types is performed in this case, which compromises the integrity of the CODESYS control runtime system by allowing potentially malicious files to be loaded onto the controller. The vulnerability has a medium severity rating with a base score of 6.5 and an exploitability score of 2.8. It requires low privileges and has no user interaction requirement, making it accessible over the network. The impact primarily affects integrity, while confidentiality remains unaffected. Organizations should remediate this vulnerability by applying patches or updates provided by Codesys to mitigate the potential danger posed by unauthorized file downloads and compromise of the control runtime system.
