Technical description

This issue affects the

ExtractEmbeddedFiles example in Apache PDFBox: from 2.0.24 through 2.0.35, from 3.0.0 through 3.0.6.

The ExtractEmbeddedFiles example contains a path traversal vulnerability (CWE-22) because

the filename that is obtained from

PDComplexFileSpecification.getFilename() is appended to the extraction path.

Users who have copied this example into their production code should

review it to ensure that the extraction path is acceptable. The example

has been changed accordingly, now the initial path and the extraction

paths are converted into canonical paths and it is verified that

extraction path contains the initial path. The documentation has also

been adjusted.

Remediation

Check the references section for vendor advisories and patches from apache. Update pdfbox-examples to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
