Title
XXE in esaml SAML library allows local file read and potential SSRF
Summary
XML External Entity (XXE) vulnerability in esaml (and its forks) allows an attacker to cause the system to read local files and incorporate their contents into processed SAML documents, and potentially perform SSRF via crafted SAML messages.
esaml parses attacker-controlled SAML messages using xmerl_scan:string/2 before signature verification without disabling XML entity expansion. On Erlang/OTP versions before 27, Xmerl allows entities by default, enabling pre-signature XXE attacks. An attacker can cause the host to read local files (e.g., Kubernetes-mounted secrets) into the SAML document. If the attacker is not a trusted SAML SP, signature verification will fail and the document is discarded, but file contents may still be exposed through logs or error messages.
This issue affects all versions of esaml, including forks by arekinath, handnot2, and dropbox. Users running on Erlang/OTP 27 or later are not affected due to Xmerl defaulting to entities disabled.

Title
Tolgee has an XXE Injection in Translation Import
Summary
Tolgee is an open-source localization platform. Prior to 3.166.3, the XML parsers used for importing Android XML resources (.xml) and .resx files don't disable external entity processing. An authenticated user who can import translation files into a project can exploit this to read arbitrary files from the server and make server-side requests to internal services. This vulnerability is fixed in 3.166.3.

OpenEMR: XInclude Injection in CCDA Import Allows Reading Arbitrary Server Files
Summary
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0.3, an authenticated user with access to the Carecoordination module can upload a crafted CCDA document containing `<xi:include href="file:///etc/passwd" parse="text"/>` to read arbitrary files from the server. Version 8.0.0.3 patches the issue.

thinkgem JeeSite Endpoint CasOutHandler.java xml external entity reference
Summary
A flaw has been found in thinkgem JeeSite up to 5.15.1. Impacted is an unknown function of the file /com/jeesite/common/shiro/cas/CasOutHandler.java of the component Endpoint. Executing a manipulation can lead to xml external entity reference. The attack may be performed from remote. Attacks of this nature are highly complex. The exploitability is considered difficult. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Title
XML Notepad: XML External Entity (XXE) Injection via Unsafe XmlTextReader in XML Diff and Schema Loading
Summary
XML Notepad is a Windows program that provides a simple intuitive User Interface for browsing and editing XML documents. Prior to version 2.9.0.21, XML Notepad does not disable DTD processing by default which means external entities are resolved automatically. There is a well known attack related to malicious DTD files where an attacker to craft a malicious XML file that loads a DTD that causes XML Notepad to make outbound HTTP/SMB requests, potentially leaking local file contents or capturing the victim's NTLM credentials. This issue has been patched in version 2.9.0.21.

Mitigation
Phases: Implementation, System Configuration
Description:
- 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.
