Title
changedetection.io: XXE vulnerability in the changedetection.io project
Summary
changedetection.io is a free open source web page change detection tool. In 0.54.9 and earlier, 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(...).

Title
Vvveb < 1.0.8.2 XML External Entity Injection via Import
Summary
Vvveb before version 1.0.8.2 contains an XML external entity (XXE) injection vulnerability in the admin Tools/Import feature that allows authenticated site_admin users to read arbitrary files and modify database records. Attackers can exploit the XML parser configuration in system/import/xml.php to inject file:// or php://filter entity references that are resolved and persisted into the application database, enabling arbitrary file disclosure and administrator password hash overwriting for privilege escalation.

Title
SolidCAM-GPPL-IDE: XML External Entity (XXE) and billion-laughs DoS in VMID parser
Summary
SolidCAM-GPPL-IDE is an unofficial, independently developed extension, Postprocessor IDE for SolidCAM. From version 1.0.0 to before version 1.0.2, Opening a .gpp file in the SolidCAM Postprocessor IDE extension causes the language server to parse a companion .vmid file from the same directory (naming convention: foo.gpp to foo.vmid). The VMID parser called XDocument.Load(path) without any XmlReaderSettings, inheriting the framework defaults which in .NET 8 allow DTD processing. A malicious .vmid file could therefore: disclose local files via external entity references, exhaust memory via recursive entity expansion, and cause denial of service via oversized or deeply nested XML. This issue has been patched in version 1.0.2.

From version 1.0.0 to before version 1.0.2, Opening a .gpp file in the SolidCAM Postprocessor IDE extension causes the language server to parse a companion .vmid file from the same directory (naming convention: foo.gpp to foo.vmid). The VMID parser called XDocument.Load(path) without any XmlReaderSettings, inheriting the framework defaults which in .NET 8 allow DTD processing. A malicious .vmid file could therefore: disclose local files via external entity references, exhaust memory via recursive entity expansion, and cause denial of service via oversized or deeply nested XML. This issue has been patched in version 1.0.2."

Mitigation

Phases: Implementation, System Configuration

Description:

  • 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.
