Advisories for Maven/Io.github.robothy/Local-S3-Rest package

The LocalS3 project, which implements an S3-compatible storage interface, contains a critical XML External Entity (XXE) Injection vulnerability in its XML parsing functionality. When processing XML requests for multipart upload operations, the application accepts and processes XML external entities, allowing an attacker to read local system files and potentially make outbound network connections. The vulnerability exists because the XML parser is configured to process external entities and DTD (Document Type …

The LocalS3 project, an S3-compatible storage service, is vulnerable to XML External Entity (XXE) injection through its bucket tagging API. The vulnerability exists because the application processes XML input without properly disabling external entity resolution. When processing XML data for bucket tagging operations, the application allows the definition and resolution of external entities. This vulnerability allows an attacker to read arbitrary files from the server's filesystem by defining an external …

The LocalS3 project contains an XML External Entity (XXE) Injection vulnerability in its bucket operations that process XML data. Specifically, the vulnerability exists in the bucket ACL and bucket tagging operations. The application processes XML input without properly disabling external entity resolution, allowing an attacker to read arbitrary files from the server's filesystem. The vulnerability occurs because the XML parser used by the application processes DOCTYPE declarations and allows external …

The LocalS3 service's bucket creation endpoint is vulnerable to XML External Entity (XXE) injection. When processing the CreateBucketConfiguration XML document during bucket creation, the service's XML parser is configured to resolve external entities. This allows an attacker to declare an external entity that references an internal URL, which the server will then attempt to fetch when parsing the XML. The vulnerability specifically occurs in the location constraint processing, where the …
