CVE-2022-29265 (GCVE-0-2022-29265)

Vulnerability from cvelistv5 – Published: 2022-04-30 08:05 – Updated: 2024-08-03 06:17
VLAI
Title
Improper Restriction of XML External Entity References in Multiple Components
Summary
Multiple components in Apache NiFi 0.0.1 to 1.16.0 do not restrict XML External Entity references in the default configuration. The Standard Content Viewer service attempts to resolve XML External Entity references when viewing formatted XML files. The following Processors attempt to resolve XML External Entity references when configured with default property values: - EvaluateXPath - EvaluateXQuery - ValidateXml Apache NiFi flow configurations that include these Processors are vulnerable to malicious XML documents that contain Document Type Declarations with XML External Entity references. The resolution disables Document Type Declarations in the default configuration for these Processors, and disallows XML External Entity resolution in standard services.
Severity
No CVSS data available.

Title
Arbitrary file access through XML parsing in org.xwiki.commons:xwiki-commons-xml
Summary
org.xwiki.commons:xwiki-commons-xml is a common module used by other XWiki top level projects. Starting in version 2.7 and prior to versions 12.10.10, 13.4.4, and 13.8-rc-1, it is possible for a script to access any file accessing to the user running XWiki application server with XML External Entity Injection through the XML script service. The problem has been patched in versions 12.10.10, 13.4.4, and 13.8-rc-1. There is no easy workaround for fixing this vulnerability other than upgrading and being careful when giving Script rights.

Title
Improper Restriction of XML External Entity Reference in Excel-Streaming-Reader
Summary
Excel-Streaming-Reader is an easy-to-use implementation of a streaming Excel reader using Apache POI. Prior to xlsx-streamer 2.1.0, the XML parser that was used did apply all the necessary settings to prevent XML Entity Expansion issues. Upgrade to version 2.1.0 to receive a patch. There is no known workaround.

CVE-2022-23170 (GCVE-0-2022-23170)

Vulnerability from cvelistv5 – Published: 2022-06-24 15:00 – Updated: 2024-09-16 19:24

Title
SysAid - Okta SSO integration
Summary
SysAid - Okta SSO integration - was found vulnerable to XML External Entity Injection vulnerability. Any SysAid environment that uses the Okta SSO integration might be vulnerable. An unauthenticated attacker could exploit the XXE vulnerability by sending a malformed POST request to the identity provider endpoint. An attacker can extract the identity provider endpoint by decoding the SAMLRequest parameter's value and searching for the AssertionConsumerServiceURL parameter's value. It often allows an attacker to view files on the application server filesystem and interact with any back-end or external systems that the application can access. In some situations, an attacker can escalate an XXE attack to compromise the underlying server or other back-end infrastructure by leveraging the XXE vulnerability to perform server-side request forgery (SSRF) attacks.

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.
