CVSS: 6.5EPSS: 0%CPEs: 1EXPL: 0CVE-2021-21238 – SAML XML Signature wrapping
https://notcve.org/view.php?id=CVE-2021-21238
21 Jan 2021 — PySAML2 is a pure python implementation of SAML Version 2 Standard. PySAML2 before 6.5.0 has an improper verification of cryptographic signature vulnerability. All users of pysaml2 that need to validate signed SAML documents are impacted. The vulnerability is a variant of XML Signature wrapping because it did not validate the SAML document against an XML schema. This allowed invalid XML documents to be processed and such a document can trick pysaml2 with a wrapped signature. • https://github.com/IdentityPython/pysaml2/commit/1d8fd268f5bf887480a403a7a5ef8f048157cc14 • CWE-347: Improper Verification of Cryptographic Signature •

21 Jan 2021 — PySAML2 is a pure python implementation of SAML Version 2 Standard. PySAML2 before 6.5.0 has an improper verification of cryptographic signature vulnerability. Users of pysaml2 that use the default CryptoBackendXmlSec1 backend and need to verify signed SAML documents are impacted. PySAML2 does not ensure that a signed SAML document is correctly signed. The default CryptoBackendXmlSec1 backend is using the xmlsec1 binary to verify the signature of signed SAML documents, but by default xmlsec1 accepts any typ... • https://github.com/RyanBoomer30/CVE-2021-21239-Exploit • CWE-347: Improper Verification of Cryptographic Signature •

https://notcve.org/view.php?id=CVE-2020-5390
13 Jan 2020 — PySAML2 before 5.0.0 does not check that the signature in a SAML document is enveloped and thus signature wrapping is effective, i.e., it is affected by XML Signature Wrapping (XSW). The signature information and the node/object that is signed can be in different places and thus the signature verification will succeed, but the wrong data will be used. This specifically affects the verification of assertion that have been signed. PySAML2 versiones anteriores a la versión 5.0.0 no comprueba que la firma en un... • https://github.com/IdentityPython/pysaml2/commit/5e9d5acbcd8ae45c4e736ac521fd2df5b1c62e25 • CWE-347: Improper Verification of Cryptographic Signature •
