Why is PeopleSoft SSO important?
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.
Security Concerns with PS_TOKEN – TokenChpoken Attack
Oracle PeopleSoft offers Single Sign On – SSO out of the box to offer the better user experience 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.
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. Read more at:
Solution for PS_TOKEN TokenChpoken Attack Vulnerability
- Disable out of the box SSO from PeopleSoft to eliminate PS_TOKEN completely.
- Enable External SSO for PeopleSoft with solutions such Microsoft Azure, CA Siteminder, Okta, Oracle Access Manager, and SSOGEN.
- Enable Multi Factor Authentication – MFA for PeopleSoft Applications
- Enable External SSO for all PeopleSoft Applications for seamless access
How to enable PeopleSoft Single Sign On?
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.

PeopleSoft SSO Configuration
Logon to Peoplesoft Console http://ps.example.com:8000/psp/ps/?cmd=start using Admin credentials(Example: PS/PS).
Navigate to Peopletools >> Security >> User Profiles >> User Profiles to create a new user profile, for example: OAMPSFT and Add Peoplesoft User.
Peopletools >> Security >> Security Objects >> Signon PeopleCode – Uncheck all options and check ‘OAMSSO_AUTHENTICATION’.
In Application Designer, Click Open and Select ‘Record’, and Open ‘FUNCLIB_LDAP’ and click Open.
Update Peoplecode of LDAPAUTH for getWWWAuthConfig() function to update defaultUserID to OAMPSFT that we have just created.
Update the user Header with PS_SSO_UID for OAMSSO_AUTHENTICATION function. SSOGEN_USER is another header variable, which is good for this function. SSOGEN_USER is available out of the box for SSOgen Integrations.
Restart PeopleSoft Services and perform SSO Login use cases.
Function OAMSSO_AUTHENTICATION() If %PSAuthResult = True And &authMethod <> "LDAP" And &authMethod <> "WWW" And &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); &authMethod = "OAMSSO"; End-If; End-If; End-If; End-Function;
