### [CVE-2024-34581](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2024-34581) ![](https://img.shields.io/static/v1?label=Product&message=n%2Fa&color=blue) ![](https://img.shields.io/static/v1?label=Version&message=0%20&color=brightgreen) ![](https://img.shields.io/static/v1?label=Version&message=n%2Fa%20&color=brightgreen) ![](https://img.shields.io/static/v1?label=Vulnerability&message=n%2Fa&color=brightgreen) ### Description The W3C XML Signature Syntax and Processing (XMLDsig) specification, starting with 1.0, was originally published with a "RetrievalMethod is a URI ... that may be used to obtain key and/or certificate information" statement and no accompanying information about SSRF risks, and this may have contributed to vulnerable implementations such as those discussed in CVE-2023-36661 and CVE-2024-21893. NOTE: this was mitigated in 1.1 and 2.0 via a directly referenced Best Practices document that calls on implementers to be wary of SSRF. ### POC #### Reference - https://www.w3.org/TR/2013/NOTE-xmldsig-bestpractices-20130411/ #### Github - https://github.com/ARPSyndicate/cve-scores - https://github.com/fkie-cad/nvd-json-data-feeds
