If the SOAP functionality is enabled, a local attacker can extract credentials to bypass the intended transfer workflow. Successful authentication against the SOAP interface grants access to privileged WCF methods, enabling an attacker to write or overwrite files within application-defined paths.\n\n## Affected\n\n- `navbox_firmware <= 4.16.1.20`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":35,"depthScoreParts":{"impact":34.7,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
