## What is CVE-2023-0100?

CVE-2023-0100 is a high-severity server-side request forgery vulnerability in The Eclipse Foundation Eclipse BIRT (Business Intelligence Reporting Tool), published on 15 Mar 2023. Any signed-in user can exploit it over the network, with no action from the victim.

### Official 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.

Weakness: CWE-20 (Improper Input Validation)

What it is: CVE-2023-0100 is a high-severity server-side request forgery vulnerability in The Eclipse Foundation Eclipse BIRT (Business Intelligence Reporting Tool), published on 15 Mar 2023. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2023-0100 in the wild and no public exploit code.

Affected packages and fixed versions:
- org.eclipse.birt:org.eclipse.birt.report.viewer (Maven): affected from 2.6.2; fixed in 4.13
- org.eclipse.birt:org.eclipse.birt.report.viewer (Maven): affected from 2.6.2; fixed in 4.13

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
