Monitor TCP ports 8080 and 8443 for HTTP POST requests to /AvalancheWeb/app/FileStoreConfig.jsf; if the linkFileStoreConfigSave parameter equals "linkFileStoreConfigSave" and the txtUncPath parameter contains "ProgramData\\Wavelink\\Avalanche", consider the request suspicious as it likely indicates exploitation of a Wavelink Avalanche vulnerability.
