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.

GHSA-58QW-P7QM-5RVH
Vulnerability from github – Published: 2023-07-10 21:52 – Updated: 2026-02-10 20:06From the reporter
XmlParseris 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
Don't use Jetty's XmlParser to parse data from users.

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.
