This allows unauthenticated remote users to retrieve files accessible to the logged-on macOS user. When a remote user sends a crafted HTTP request to the server, it triggers a code path that will download a configuration file from a specified remote machine over HTTP. There is an XXE flaw in processing of this configuration file that allows reading local (to macOS) files and uploading them to remote machines.", "severity": [], "affected": [], "references": [ { "type": "ADVISORY", "url": "https://nvd.nist.gov/vuln/detail/CVE-2021-34823" }, { "type": "WEB", "url": "https://www.trustwave.com/en-us/resources/security-resources/security-advisories" }, { "type": "WEB", "url": "https://www.trustwave.com/en-us/resources/security-resources/security-advisories/?fid=29105" } ], "database_specific": { "cwe_ids": [ "CWE-611" ], "severity": "CRITICAL", "github_reviewed": false, "github_reviewed_at": null, "nvd_published_at": "2021-08-13T17:15:00Z" } }
