CSRF and Fingerprint token handling added to custom URL generation
Resolved in Pega Version 8.4
An error screen appeared with the message "Server response error, no update data returned" while doing a check out and check in of the offer rule. This was traced to CSRF token validation: in this scenario, a custom URL was being framed and the corresponding request did not have a valid CSRF/ Fingerprint token, which can occur when there are custom AJAX/Non-ajax URLs constructed manually in the non-autogenerated/HTML streams. To address this, handling has been added for CSRF and fingerprint tokens as part of the custom URL generation.

URL Encryption and Obfuscation made compatible with site-minder
Resolved in Pega Version 8.4
Attempting to install a DL using Hfix Manager worked when not going through SSO but failed when using SSO. Investigation showed that this was due to the use of URLEncryption: URLEncryption uses a Pega-supplied base64 to encode the cipher text with MIME type encoding by default, which adds newline character after every 72 characters. This is not compatible with site-minder. which has policies to restrict newline characters in the URL. As a result, none of the encrypted requests were being processed. To resolve this, post-processing logic has been added to remove newline characters from encoded text. This change has also been applied top URLObfuscation.

Support added for Authentication service rule attributes in embedded pages
Resolved in Pega Version 8.4
SSO login was not working, giving the error "Unable to process the SAML WebSSO request : No value specified for Attribute in SAML assertion". Investigation showed the Authentication service rule could only map attributes that are on the top level page and did not consider embedded page values. To resolve this, tools.getProperty will be used to fetch the property reference value instead of find Page and getString.

Authorization header base 64 format error recategorized as debug logging
Resolved in Pega Version 8.4
Numerous messages were generated indicating that the Authorization Header format was invalid when using the format " : " (Base64 Og==) . As this is the default behavior for a particular class of proxy servers, the error statement has been updated to be logged as a debug statement and will be visible only when that logging is enabled.

Web Tier busy threads released on timeout
Resolved in Pega Version 8.6.1
Tomcat Web Tier Busy Threads were not being correctly released, causing stability and performance problems that included health check pings not receiving a thread to service the request so the node was marked as bad, users were quiesced, and the node replaced. Investigation showed the 'put' on the blocking queue did not time out when the queue was full and waited indefinitely, keeping the thread blocked. To resolve this, the system will use 'offer' on the blocking queue instead of 'put' to force thread release on timeout. In addition, debug logs have been added to understand when the offer (or Put) does not succeed and the state of the queue that is causing this issue; the debug logs for class com.pega.pegarules.session.internal.serverpush.RoboticAutomationImpl should be enabled only if the thread busy issue is observed and for limited time window while actively debugging.

Resolved Push Node Daily Information exception
Resolved in Pega Version 8.6.1
The "Push Nodes Info Daily" agent was generating an exception on each of the nodes. This has been resolved by enhancing the PegaAESRemote code to handle the exception and get the node info locally, then push it to the console when it is not able to get it via the cluster management API.

Certificate match will use Subject Distinguished Name
Resolved in Pega Version 8.6.1
Signature verification was failing due to the system not finding the matching root certificate for the chain. The root certificate was in the trust store, but the system found a different certificate first and that other certificate (an intermediate certificate) was not considered a valid certificate for validating the whole certificate chain. This was traced to filtering on the Issuer Distinguished Name (DN) instead of the Subject DN and was due to intermediate certificates potentially having the same Issuer as a root certificate (e.g. if that root certificate was used to create the intermediate certificate). To resolve this, an update has been made to check the Subject DN instead of Issuer DN.
