Vulnerability from github – Published: 2024-06-20 15:31 – Updated: 2025-11-04 18:31
VLAI
Details

When the Kiuwan Local Analyzer uploads the scan results to the Kiuwan SAST web application (either on-premises or cloud/SaaS solution), the transmitted data consists of a ZIP archive containing several files, some of them in the XML file format. During Kiuwan's server-side processing of these XML files, it resolves external XML entities, resulting in a XML external entity injection attack. An attacker with privileges to scan source code within the "Code Security" module is able to extract any files of the operating system with the rights of the application server user and is potentially able to gain sensitive files, such as configuration and passwords. Furthermore, this vulnerability also allows an attacker to initiate connections to internal systems, e.g. for port scans or accessing other internal functions / applications such as the Wildfly admin console of Kiuwan.

This issue affects Kiuwan SAST: <master.1808.p685.q13371

Honeywell Saia PG5 Controls Suite XML External Entity Processing Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Honeywell Saia PG5 Controls Suite. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

The specific flaw exists within the parsing of XML files. Due to the improper restriction of XML External Entity (XXE) references, a crafted document specifying a URI causes the XML parser to access the URI and embed the contents back into the XML document for further processing. An attacker can leverage this vulnerability to disclose information in the context of the current process. Was ZDI-CAN-18456.

Vulnerability from github – Published: 2023-07-10 21:52 – Updated: 2026-02-10 20:06
VLAI
Summary
Eclipse Jetty XmlParser allows arbitrary DOCTYPE declarations
Details

From the reporter

XmlParser is vulnerable to XML external entity (XXE) vulnerability. XmlParser is being used when parsing Jetty’s xml configuration files. An attacker might exploit this vulnerability in order to achieve SSRF or cause a denial of service. One possible scenario is importing a (remote) malicious WAR into a Jetty’s server, while the WAR includes a malicious web.xml.

Impact

There are no circumstances in a normally deployed Jetty server where potentially hostile XML is given to the XmlParser class without the attacker already having arbitrary access to the server. I.e. in order to exploit XmlParser the attacker would already have the ability to deploy and execute hostile code. Specifically, Jetty has no protection against malicious web application and potentially hostile web applications should only be run on an isolated virtualisation.

Thus this is not considered a vulnerability of the Jetty server itself, as any such usage of the jetty XmlParser is equally vulnerable as a direct usage of the JVM supplied SAX parser. No CVE will be allocated to this advisory.

However, any direct usage of the XmlParser class by an application may be vulnerable. The impact would greatly depend on how the application uses XmlParser, but it could be a denial of service due to large entity expansion, or possibly the revealing local files if the XML results are accessible remotely.

Patches

Ability to configure the SAXParserFactory to fit the needs of your particular XML parser implementation have been merged as part of PR #10067

Workarounds

  "details": "### From the reporter\n\n\u003e `XmlParser` is vulnerable to XML external entity (XXE) vulnerability.\n\u003e  XmlParser is being used when parsing Jetty\u2019s xml configuration files. An attacker might exploit\n\u003e this vulnerability in order to achieve SSRF or cause a denial of service.\n\u003e One possible scenario is importing a (remote) malicious WAR into a Jetty\u2019s server, while the\n\u003e WAR includes a malicious web.xml.\n\n### Impact\nThere are no circumstances in a normally deployed Jetty server where potentially hostile XML is given to the XmlParser class without the attacker already having arbitrary access to the server. I.e. in order to exploit `XmlParser` the attacker would already have the ability to deploy and execute hostile code.  Specifically, Jetty has no protection against malicious web application and potentially hostile web applications should only be run on an isolated virtualisation.  \n\nThus this is not considered a vulnerability of the Jetty server itself, as any such usage of the jetty XmlParser is equally vulnerable as a direct usage of the JVM supplied SAX parser.  No CVE will be allocated to this advisory.\n\nHowever, any direct usage of the `XmlParser` class by an application may be vulnerable.  The impact would greatly depend on how the application uses `XmlParser`, but it could be a denial of service due to large entity expansion, or possibly the revealing local files if the XML results are accessible remotely.\n\n### Patches\nAbility to configure the SAXParserFactory to fit the needs of your particular XML parser implementation have been merged as part of PR #10067\n\n### Workarounds\nDon\u0027t use Jetty\u0027s `XmlParser` to parse data from users.",

Mitigation
Implementation System Configuration

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.
