### Impact OpenAM up to version 14.7.2 does not properly validate the signature of SAML responses received as part of the SAMLv1.x Single Sign-On process. Attackers can use this fact to impersonate any OpenAM user, including the administrator, by sending a specially crafted SAML response to the SAMLPOSTProfileServlet servlet.

### Patches This problem has been patched in OpenAM 14.7.3-SNAPSHOT and later

### Workarounds One should comment servlet `SAMLPOSTProfileServlet` in web.xml or disable SAML in OpenAM ```xml <servlet> <description>SAMLPOSTProfileServlet</description> <servlet-name>SAMLPOSTProfileServlet</servlet-name> <servlet-class>com.sun.identity.saml.servlet.SAMLPOSTProfileServlet</servlet-class> </servlet> ... <servlet-mapping> <servlet-name>SAMLSOAPReceiver</servlet-name> <url-pattern>/SAMLSOAPReceiver</url-pattern> </servlet-mapping> ```
