Attackers can exploit the macro dispatcher's lack of authorization model combined with the path resolver's failure to confine absolute paths to manipulate the template engine and compromise the confidentiality, integrity, and availability of the host.","cvssScore":10,"cvssSeverity":"CRITICAL","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","cwes":["CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://github.com/wgetnz/hfs2/blob/master/advisories/hfs2-template-macro-missing-authorization/README.md","tags":[]},{"url":"https://www.vulncheck.com/advisories/hfs2-unauthenticated-arbitrary-file-read-write-via-template-engine","tags":[]}],"exploitRefs":[{"url":"https://github.com/wgetnz/hfs2/blob/master/advisories/hfs2-template-macro-missing-authorization/README.md","tags":[]}],"hasPoc":true,"ai":{"summary":"HFS2 version 2.4.0 and earlier allows unauthenticated attackers to read, write, append, and delete files, posing a significant risk to the confidentiality, integrity, and availability of the host.","exploitability":"Exploitation is relatively straightforward due to the lack of authentication checks and the failure to confine absolute paths.","blast_radius":"If exploited, the impact could be severe, compromising the entire filesystem accessible to the HFS service account.","remediation":"Upgrade to HFS2 version 2.5.0 or later.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["rce","auth-bypass","file-access"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-09-27T08:46:17.776Z"}}
