Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Requires verification of individual access authorizations before granting facility entry, addressing missing authentication for critical physical access.
Knowing every system allows confirmation that critical functions are not left without required authentication mechanisms.
Requires authentication gates on critical functions that must remain unavailable to anonymous public users.
Decoy implementations of critical functions without authentication lure and record attackers probing for missing auth checks.
Requires established identification and authentication to unlock, mitigating missing authentication for continued system access.
Requiring identification and rationale for actions allowed without authentication ensures critical functions are not left unprotected by forcing review of authentication requirements.
Authorizing mobile device connections to organizational systems ensures authentication is performed for this critical access function.
Controls on authorized publication limit files and directories with nonpublic data from becoming accessible to external parties.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Unauthenticated access to public REST API enables arbitrary local file read (T1005) via path-controlled payload loading; directly matches public-facing app exploitation (T1190).
NVD Description
Dalfox is a powerful open-source XSS scanner and utility focused on automation. Prior to 2.13.0, when dalfox is run in REST API server mode, the custom-payload-file field in model.Options is JSON-tagged and deserialized directly from the attacker's request body, then…

propagated unchanged through dalfox.Initialize into the scan engine. The engine passes the value to voltFile.ReadLinesOrLiteral, which reads lines from any file path accessible to the dalfox process and embeds each line as an XSS payload in outbound HTTP requests directed at the attacker-controlled target URL. Because the server has no API key by default, an unauthenticated network attacker can exfiltrate the contents of arbitrary files on the dalfox host by reading them line-by-line through scan traffic. This vulnerability is fixed in 2.13.0.
