Summary
OpenRemote has XXE in Velbus Asset Import
Details

Summary

The Velbus asset import path parses attacker-controlled XML without explicit XXE hardening. An authenticated user who can call the import endpoint may trigger XML external entity processing, which can lead to server-side file disclosure and SSRF. The target file must be less than 1023 characters.

Details

Velbus import uses DocumentBuilderFactory.newInstance().newDocumentBuilder().parse(...) on untrusted XML input, without explicit safeguards to disable DTD/external entities.

```154:165:agent/src/main/java/org/openremote/agent/protocol/velbus/AbstractVelbusProtocol.java @Override public Future startAssetImport(byte[] fileData, Consumer assetConsumer) {

    return executorService.submit(() -> {
        Document xmlDoc;
        try {
            String xmlStr = new String(fileData, StandardCharsets.UTF_8);
            LOG.info("Parsing VELBUS project file");

            xmlDoc = DocumentBuilderFactory
                .newInstance()
                .newDocumentBuilder()
                .parse(new InputSource(new StringReader(xmlStr)));


Expanded `Caption` content is propagated into created asset names:

```193:198:agent/src/main/java/org/openremote/agent/protocol/velbus/AbstractVelbusProtocol.java
                String name = module.getElementsByTagName("Caption").item(0).getTextContent();
                name = isNullOrEmpty(name) ? deviceType.toString() : name;

                // TODO: Use device specific asset types
                Asset<?> device = new ThingAsset(name);

PoC

  1. Log in to a realm with a user that can call Velbus asset import.
  2. Create/select a Velbus TCP Agent in that same realm.
  3. Send POST /api/{realm}/agent/assetImport/{agentId} with a Velbus project XML payload and compare behavior against a baseline import file.
  4. Save the below code as a xxe.xml and upload to Setup under https://localhost/manager/?realm=<YOUR_REALM>#/assets/false/<ASSET_ID>. Chnage the file:///etc/passwd to another file if your passwd is longer than 1023 characters.
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE velbus [
  <!ENTITY xxe SYSTEM "file:///etc/passwd">
]>
<Project>
  <Module type="VMB1RY" address="01" build="00" serial="LAB">
    <Caption>&xxe;</Caption>
  </Module>
</Project>

As long as the file content is under 1023 characters, the exploit will succeed. image

If the file content reaches the limit, an error is thrown. image

Impact

  • Type: XML External Entity (XXE)
  • Affected: Deployments exposing Velbus import to authenticated users with import access
  • Risk: limited local file disclosure (as long as the file is under 1023 characters) from the Manager runtime, and SSRF.

Vulnerability from github – Published: 2024-11-18 18:30 – Updated: 2024-11-18 18:30
VLAI
Details

A vulnerability in the web UI of Cisco SD-WAN vManage Software could allow an authenticated, remote attacker to gain read and write access to information that is stored on an affected system. The vulnerability is due to improper handling of XML External Entity (XXE) entries when parsing certain XML files. An attacker could exploit this vulnerability by persuading a user to import a crafted XML file with malicious entries. A successful exploit could allow the attacker to read and write files within the affected application.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Details

SRS Policy Manager 6.X is affected by an XML External Entity Injection (XXE) vulnerability due to a misconfigured XML parser that processes user-supplied DTD input without sufficient validation. A remote unauthenticated attacker can potentially exploit this vulnerability to read system files as a non-root user and may be able to temporarily disrupt the ESRS service.

Vulnerability from github – Published: 2024-05-03 03:30 – Updated: 2024-05-03 03:30
VLAI
Details

Inductive Automation Ignition SimpleXMLReader XML External Entity Processing Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Inductive Automation Ignition. Authentication is required to exploit this vulnerability.

The specific flaw exists within the SimpleXMLReader class. 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 SYSTEM. Was ZDI-CAN-17571.

Details

An External XML entity (XXE) vulnerability in ePO prior to 5.10 Update 14 can lead to an unauthenticated remote attacker to potentially trigger a Server Side Request Forgery attack. This can be exploited by mimicking the Agent Handler call to ePO and passing the carefully constructed XML file through the API.

Vulnerability from github – Published: 2022-09-22 00:00 – Updated: 2022-12-05 22:12

Summary
Jenkins Compuware Common Configuration Plugin vulnerable to Improper Restriction of XML External Entity Reference
Details

Jenkins Compuware Common Configuration Plugin 1.0.14 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.

This allows attackers able to change the contents of the Topaz Workbench CLI home directory on agents to have Jenkins parse a crafted file that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.

7.1 (High)

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.
