Summary
changedetection.io project has an XXE vulnerability
Details

changedetection.io_XXE_01 Vulnerability Report: We discovered a XXE vulnerability in the changedetection.io project

While analyzing the code logic, it was determined that an area may lead to unintended behavior under specific conditions. With the project's security in mind, see the analysis results to discern whether this may indicate a potential security risk.

Overview

  • SOURCE_VERSION: 0.54.9 (9f3a9fdc18bba404244801e5df8109e213ce9ff4)
  • Vulnerability type: XXE
  • Finding title: XML XPath helpers parse untrusted XML with entity resolution left to lxml defaults
  • Affected location: changedetectionio/html_tools.py:287

Root Cause

xpath_filter() switches to XML mode for XML/RSS content and creates etree.XMLParser(strip_cdata=False) without explicitly disabling external entity resolution, external DTD loading, or network-backed entity lookup. The helper then parses untrusted XML bytes directly with etree.fromstring(...).

Source-to-Sink Chain

  1. Untrusted XML/RSS response content is fetched from monitored URLs.
  2. Stream detection marks the content as XML/RSS and the include-filter path invokes xpath_filter(..., is_xml=True).
  3. xpath_filter() builds the default XML parser and calls etree.fromstring(...) at changedetectionio/html_tools.py:287.
  4. External entity declarations in attacker XML can be expanded by parser-default behavior in affected runtime combinations.

Exploitation Preconditions

  1. Attacker controls the watched XML/RSS response body.
  2. The watch uses an XPath include filter that triggers XML helper parsing.
  3. Runtime parser behavior allows external entity expansion (for example, vulnerable dependency/default combinations).
  4. The process can read the referenced local resource.

Risk

The XML helper path can turn watch processing into a local file disclosure primitive when entity expansion is enabled by parser defaults.

Impact

Sensitive local files can be exposed into extracted watch output, diff history, and downstream notification channels.

Remediation

  1. Harden XML parser construction with resolve_entities=False, load_dtd=False, and no_network=True.
  2. Reject DOCTYPE/entity declarations for untrusted XML if DTD features are unnecessary.
  3. Add regression tests that assert external entities are never expanded in XPath XML helper flows.

GHSA-V8JR-7G4W-CP39

Vulnerability from github – Published: 2025-07-22 15:32 – Updated: 2025-11-05 00:31
VLAI
Details

An XML External Entity (XXE) injection vulnerability exists in ETQ Reliance on the CG (legacy) platform within the /resources/sessions/sso endpoint. The SAML authentication handler processes XML input without disabling external entity resolution, allowing crafted SAML responses to invoke external entity references. This could enable attackers to retrieve sensitive files or perform server-side request forgery (SSRF). The issue was addressed by disabling external entity processing for the affected XML parser in versions SE.2025.1 and 2025.1.2.

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.
