PeopleSoft SSO Integrations

PeopleSoft Single Signon Integration with NextGen SSO Solution

What is PeopleSoft Single Signon – SSO?

PeopleSoft SSO is most desired for PeopleSoft Portal implementations, as PeopleSoft Portal is the central and unified interface to access other PeopleSoft Applications, such as HCM or CRM. PeopleSoft SSO authenticates the user during the first login to PeopleSoft Portal, then allows the user to access other PeopleSoft Applications without forcing the user to login to the each application over and over. Therefore, SSO is a must have for PeopleSoft Applications. Unlike other applications, Oracle PeopleSoft offers Single Signon – SSO out of the box to offer the better user expereince for its customers. This out of the box PeopleSoft SSO uses PS_TOKEN cookie to store the user or session information to pass from PeopleSoft Application to another.

Security Concerns with PS_TOKEN – TokenChpoken Attack

PS_TOKEN cookie stores confidential information such as UserID – Name of the Authenticated User, Node Name – Node Name Authenticated the user, Date And Time – when the PS_TOKEN was issued, and SHA Signature in base64 encoded.

According to ERPScan report about Oracle PeopleSoft vulnerabilities, PeopleSoft Applications are susceptible to the TokenChpoken attack, which affects systems that use Single Sign On SSO, is possible because an PS_TOKEN Authentication cookie used by PeopleSoft Applications can be forged. When the PS_TOKEN is identified by a “brute force” TokenChpoken attack, it is possible to log in under a system account and gain access to all data from the compromised system. The following are the quick references.

 

Solution for PS_TOKEN TokenChpoken Attack Vulnerability

  1. Disable out of the box SSO from PeopleSoft to eliminate PS_TOKEN completely.
  2. Enable External SSO for PeopleSoft with solutions such Microsoft Azure, CA Siteminder, Okta, Oracle Access Manager, and SSOGEN.
  3. Enable Multi Factor Authentication – MFA for PeopleSoft Applications
  4. Enable External SSO for all PeopleSoft Applications for seamless access

How to enable PeopleSoft Single Signon?

Reverse Proxy

Configure Apache or Oracle HTTP Server Reverse Proxy to front-end all the PeopleSoft Servers, proxying /psp/, /ps, /psc, amd /cs URIs.

Disable Direct Access

Ensure that all the traffic is routed through the above webserver and Disable direct access to PeopleSoft Server URLs.
 

Enable External SSO

Enable SSO at Web Server – Reverse Proxy and Configure SSO in PeopleSoft. Header Injection and Cookie forgery are completely eliminated.

         &authMethod <> "OSSO" And
         &authMethod <> "SSO" Then
      getWWWAuthConfig();
      If %SignonUserId = &defaultUserId Then
         &userID = %Request.GetHeader("PS_SSO_UID");
         If &userID <> "" Then
            If &bConfigRead = False Then
               getLDAPConfig();
            End-If;
            SetAuthenticationResult(True, &userID, "", False);
