A CSV injection vulnerability exists in SYS600. Injected malicious formulas can add or modify data to the spreadsheet, insert links, exfiltrate data, and in some cases, depending on how the user has their environment configured, execute malicious code on the user's machine. To exploit this issue attackers would need a way to create arbitrary log messages, achievable through normal functionality via SCIL scripts, a log injection vulnerability, or via the SYS600 broker.
