| CVE-2021-21239 | 2 Debian, Pysaml2 Project | 2 Debian Linux, Pysaml2 | 2021-03-10 | 4.3 MEDIUM | 6.5 MEDIUM |
| 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 type of key found within the given document. xmlsec1 needs to be configured explicitly to only use only _x509 certificates_ for the verification process of the SAML document signature. This is fixed in PySAML2 6.5.0. | |||||
| CVE-2021-21238 | 1 Pysaml2 Project | 1 Pysaml2 | 2021-01-29 | 4.3 MEDIUM | 6.5 MEDIUM |
| 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. This is fixed in PySAML2 6.5.0. | |||||
| CVE-2017-1000246 | 1 Pysaml2 Project | 1 Pysaml2 | 2019-10-03 | 5.0 MEDIUM | 5.3 MEDIUM |
| Python package pysaml2 version 4.4.0 and earlier reuses the initialization vector across encryptions in the IDP server, resulting in weak encryption of data. | |||||
