Vulnerabilities in cloud service disclosed.
A vulnerability exists in Google Cloud's Document AI service which could facilitate data exfiltration.
According to media reports, an attacker with adequate permissions could establish or alter processors even in organizations not using Document AI due to access being provided by the service's Core Service Agent, said researchers from Vectra AI.
The researchers determined that as Document AI allows users to process documents stored in Cloud Storage by creating both online (standard) jobs and offline (batch) processing jobs; when performing batch processing, the service utilizes the Document AI Core Service Agent to handle data ingestion and output the results.
“Critically, this service agent possesses broad permissions to access any Cloud Storage bucket within the same project,” researchers said.
On top of that, the Document AI service is vulnerable to transitive access abuse, which can lead to unauthorised access and data theft.
