GHSA-J5G2-Q29X-CW3H
Vulnerability from github – Published: 2024-12-02 20:00 – Updated: 2024-12-04 16:13Withdrawn Advisory
This advisory has been withdrawn because the vulnerability affects users of the SimpleSAMLphp tarball, not the SimpleSAMLphp Composer package. The underlying information about CVE-2024-52596 is still valid.
Original Description
Summary
When loading an (untrusted) XML document, for example the SAMLResponse, it's possible to induce an XXE.
Mitigation:
Remove the LIBXML_DTDLOAD | LIBXML_DTDATTR options from $options is in: https://github.com/simplesamlphp/saml2/blob/717c0adc4877ebd58428637e5626345e59fa0109/src/SAML2/DOMDocumentFactory.php#L41

Mitigation
Many XML parsers and validators can be configured to disable external entity expansion.
CAPEC-221: Data Serialization External Entities Blowup
This attack takes advantage of the entity replacement property of certain data serialization languages (e.g., XML, YAML, etc.) where the value of the replacement is a URI. A well-crafted file could have the entity refer to a URI that consumes a large amount of resources to create a denial of service condition. This can cause the system to either freeze, crash, or execute arbitrary code depending on the URI.
