CVE-2019-1698 — Cisco Iot Field Network Director security vulnerability
A vulnerability in the web-based user interface of Cisco Internet of Things Field Network Director (IoT-FND) Software could allow an authenticated, remote attacker to gain read access to information that is stored on an affected system. The vulnerability is due to improper handling of XML External Entity (XXE) entries when parsing certain XML files. An attacker could exploit this vulnerability by importing a crafted XML file with malicious entries, which could allow the attacker to read files within the affected application. Versions prior to 4.4(0.26) are affected.

Matched remediation archetype
XML external entity and unsafe XML processing
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Inventory XML parsers used by APIs, file imports, office or image formats, identity protocols, feeds, and background jobs.
- Determine whether document type declarations, external entities, XInclude, schemas, or network resolvers are enabled.
- Map parser filesystem and network access and the sensitivity of documents it processes.
Remediate safely
- Configure each parser to reject document type declarations and disable external entity, XInclude, and network resolution features.
- Prefer a data format or hardened parser that does not support external resolution, and apply input size and depth limits.
- Update affected XML libraries and centralize secure parser construction so callers cannot silently override it.
