Name of the Vulnerable Software and Affected Versions
veraPDF versions 1.17.35 through 1.30.1
veraPDF versions 1.31.0 through 1.31.70
Description
An XML External Entity (XXE) issue exists in the
validation-model/src/main/java/org/verapdf/gf/model/impl/pd/GFPDAcroForm.java file within the getdynamicRender() function. The problem occurs when the software uses a default-configured DocumentBuilderFactory to parse an XML stream from the /XFA entry of a PDF's /AcroForm dictionary without enabling security features such as disallow-doctype-decl. A remote attacker can provide a crafted PDF containing a malicious XFA stream that triggers external entity expansion during PDF/UA-1 validation. This can lead to local file disclosure or Server-Side Request Forgery (SSRF), where the server is coerced into making outbound requests.Recommendations
Update veraPDF to version 1.30.2.
Update veraPDF to version 1.31.71.
As a temporary mitigation, restrict the validation of PDFs against the PDF/UA-1 profile to minimize the risk of exploitation.
Fix
XXE
