<p>PySAML2 is a pure python implementation of SAML2</p>

|
||
<description>
|
||
<p>It was found that the PySAML2 relies on an assert statement to check the
|
||
user’s password. A python optimizations might remove this assertion.

|
||
<impact type="normal">
|
||
<p>A remote attacker could bypass security restrictions and access any
|
||
application which is using PySAML2 for authentication.
|
||
</p>
|
||
</impact>
|
||
<workaround>
|
||
<p>Disable python optimizations.</p>
|
