CVE-2017-7375

libxml2: Missing validation for external entities in xmlParsePEReference

Published Feb 19, 2018 CVSS 3.1 · 9.8 Critical EPSS 3.0% KEV · Not listed
Description
A flaw in libxml2 allows remote XML entity inclusion with default parser flags (i.e., when the caller did not request entity substitution, DTD validation, external DTD subset loading, or default DTD attributes). Depending on the context, this may expose a higher-risk attack surface in libxml2 not usually reachable with default parser flags, and expose content from local files, HTTP, or FTP servers (which might be otherwise unreachable).
