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.Show less

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.Show less

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.Show less

An issue was discovered in Zimbra Collaboration (ZCS) 10.0 and 10.1. An XML External Entity (XXE) vulnerability exists in the Zimbra Exchange Web Services (EWS) SOAP interface due to improper handling of XML input. An authenticated attacker can submit crafted XML data that is processed by an XML parser with external entity resolution enabled. Successful exploitation may allow disclosure of sensitive local files from the server.Show less

Improper Restriction of XML External Entity Reference vulnerability in XMLUtils.java in Slovensko.Digital Autogram allows remote unauthenticated attacker to conduct SSRF (Server Side Request Forgery) attacks and obtain unauthorized access to local files on filesystems running the vulnerable application. Successful exploitation requires the victim to visit a specially crafted website that sends request containing a specially crafted XML document to /sign endpoint of the local HTTP server run by the application.Show less

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.Show less

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.Show less

An XML External Entity (XXE) vulnerability allows malicious user to perform Server-Side Request Forgery (SSRF) via crafted XML input containing malicious external entity references. This issue affects Xerox FreeFlow Core versions up to and including 8.0.7.  Please consider upgrading to FreeFlow Core version 8.1.0 via the software available on -  https://www.support.xerox.com/en-us/product/core/downloadsShow less

IBM Db2 for Linux, UNIX and Windows (includes Db2 Connect Server) 11.5.0 through 11.5.9 and 12.1.0 through 12.1.3 is vulnerable to an XML external entity injection (XXE) attack when processing XML data. A remote attacker could exploit this vulnerability to expose sensitive information or consume memory resources.Show less

A vulnerability was determined in opencc JFlow up to 20260129. This affects the function Imp_Done of the file src/main/java/bp/wf/httphandler/WF_Admin_AttrFlow.java of the component Workflow Engine. This manipulation of the argument File causes xml external entity reference. The attack may be initiated remotely. The exploit has been publicly disclosed and may be utilized. The project was informed of the problem early through an issue report but has not responded yet.Show less

MSN Password Recovery 1.30 contains an XML external entity injection vulnerability that allows attackers to read local system files through crafted XML input. Attackers can exploit the 'Favorites' tab by injecting a malicious XML file that references external entities to retrieve sensitive system configuration information.Show less

CWE-611: Improper Restriction of XML External Entity Reference vulnerability exists that could cause unauthorized disclosure of local files, interaction within the EBO system, or denial of service conditions when a local user uploads a specially crafted TGML graphics file to the EBO server from Workstation.Show less

A vulnerability was identified in O2OA up to 9.0.0. This impacts an unknown function of the file /x_program_center/jaxrs/mpweixin/check of the component HTTP POST Request Handler. The manipulation leads to xml external entity reference. It is possible to initiate the attack remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.Show less

Asterisk is an open source private branch exchange and telephony toolkit. Prior to versions 20.7-cert9, 20.18.2, 21.12.1, 22.8.2, and 23.2.2, the ast_xml_open() function in xml.c parses XML documents using libxml with unsafe parsing options that enable entity expansion and XInclude processing. Specifically, it invokes xmlReadFile() with the XML_PARSE_NOENT flag and later processes XIncludes via xmlXIncludeProcess().If any untrusted or user-supplied XML file is passed to this function, it can allow an attacker to trigger XML External Entity (XXE) or XInclude-based local file disclosure, potentially exposing sensitive files from the host system. This can also be triggered in other cases in which the user is able to supply input in xml format that triggers the asterisk process to parse it. This issue has been patched in versions 20.7-cert9, 20.18.2, 21.12.1, 22.8.2, and 23.2.2.Show less

Improper Restriction of XML External Entity Reference vulnerability in Apache Syncope Console. An administrator with adequate entitlements to create or edit Keymaster parameters via Console can construct malicious XML text to launch an XXE attack, thereby causing sensitive data leakage occurs. This issue affects Apache Syncope: from 3.0 through 3.0.15, from 4.0 through 4.0.3. Users are recommended to upgrade to version 3.0.16 / 4.0.4, which fix this issue.Show less
