Pysaml2 Project Pysaml2 vulnerabilities

CVE-2016-10127 [CRITICAL] CWE-611 PySAML2 XML external entity attack PySAML2 XML external entity attack PySAML2 allows remote attackers to conduct XML external entity (XXE) attacks via a crafted SAML XML request or response.

CVE-2021-21239 [MEDIUM] CWE-347 CVE-2021-21239: PySAML2 is a pure python implementation of SAML Version 2 Standard. PySAML2 before 6.5.0 has an impr 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 sign

CVE-2021-21238 [MEDIUM] CWE-347 CVE-2021-21238: PySAML2 is a pure python implementation of SAML Version 2 Standard. PySAML2 before 6.5.0 has an impr 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 a

CVE-2020-5390 [HIGH] CWE-347 CVE-2020-5390: PySAML2 before 5.0.0 does not check that the signature in a SAML document is enveloped and thus sign 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. T

CVE-2017-1000433 [HIGH] CWE-287 CVE-2017-1000433: pysaml2 version 4.4.0 and older accept any password when run with python optimizations enabled. This pysaml2 version 4.4.0 and older accept any password when run with python optimizations enabled. This allows attackers to log in as any user without knowing their password.

CVE-2017-1000246 [MEDIUM] CWE-330 CVE-2017-1000246: Python package pysaml2 version 4.4.0 and earlier reuses the initialization vector across encryptions 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.

CVE-2016-10149 [HIGH] CWE-611 CVE-2016-10149: XML External Entity (XXE) vulnerability in PySAML2 4.4.0 and earlier allows remote attackers to read XML External Entity (XXE) vulnerability in PySAML2 4.4.0 and earlier allows remote attackers to read arbitrary files via a crafted SAML XML request or response.
