UPDATE: DocuSign’s online validation tool patched

In January this year, DocuSign patched its online digital signature validation tool (validator.docusign.com) to ensure it could address the three digital signature vulnerabilities identified in a research paper by a team from Ruhr-University Bochum in Germany.

Those vulnerabilities related to online validation services in general—they had no impact on the integrity or validity of a digital signature written to a document by the core DocuSign eSignature solution. In addition, given DocuSign had already patched the validator tool before the research paper was published, we have asked the researchers to update their online records accordingly.
