Overview
Affected versions of this package are vulnerable to External Control of File Name or Path through the importSY, importZipMd, importSyncProviderWebDAV, importSyncProviderS3, and importConf file import processes in the kernel/api/import.go, kernel/api/sync.go, and kernel/api/system.go` components. An attacker can write files outside the intended import directory, potentially achieving code execution or overwriting application data, by supplying a crafted multipart filename.
Note: This is only exploitable if the attacker has administrative privileges.
