Pivotal CRM Unsafe Deserialization Vulnerability (CWE-502) Advisory and Patch Guide

Vulnerability Overview Vulnerability Name: Insecure Deserialization (CWE-502) Vulnerability Description: This vulnerability involves insecure deserialization in Pivotal version 6.6.04.08. The issue arises from the use of for handling request/response payloads and persistent state. Attackers can trigger gadget-chain deserialization by manipulating serialized input, leading to Remote Code Execution (RCE). Affected Scope Affected Versions: Pivotal 6.6.04.08 Affected Components: - Pivotal Package Client (Smart Client) - Pivotal Business Server (PBS) Remediation Recommended Fix: Upgrade to Pivotal CRM 6.6.5.10 - Version 6.6.5.10 includes a comprehensive fix for CWE-502 and enhances security protections for data processing platforms. - Upgrade Steps: 1. Download the 6.6.5.10 installer from the download portal. 2. Refer to the release notes and upgrade guide. 3. No additional actions are required; the fix is automatically included in the upgrade. Alternative Fix: For environments that cannot upgrade to 6.6.5.10, apply the patch package . - The patch package includes the following fixes: - Smart Client: 1. Stop the Pivotal Smart Client service. 2. Backup existing DLLs (e.g., ). 3. Replace with the DLL from the patch package ( ). 4. Restart the Smart Client service. - PBS: 1. Stop the Pivotal Business Server service. 2. Backup existing DLLs (e.g., ). 3. Replace with the DLL from the patch package ( ). 4. Restart the PBS service. - Deployment Order: If using both Smart Client and PBS, deploy the PBS patch first, or deploy both patches simultaneously to avoid compatibility issues. Verification After deploying the patch, confirm that Smart Client functions normally (login and read/write operations). Confirm that the PBS service is running properly and Smart Client can connect. Re-run the initial security tests that flagged the issue to confirm that deserialization/RCE payloads are blocked. Considerations After updating the Smart Client DLL, users may need to re-authenticate. If the security report identifies other issues (such as unencrypted HTTP traffic), they must be addressed separately. Frequently Asked Questions How to confirm if affected: If a security scan reports CWE-502 and identifies the use of .NET , the system may be affected. Do Smart Client and PBS need to be patched simultaneously: If both components are in scope, both should be patched; if only one component is in scope, patch only that component. Changes after patching: Smart Client no longer uses , and PBS prevents dangerous deserialization types via . Patch Download Patch Package: Patch_CWE502_20260316.zip (274 KB) --- Summary: This vulnerability involves insecure deserialization affecting the Smart Client and PBS components in Pivotal version 6.6.04.08. Upgrading to version 6.6.5.10 is recommended, or the patch package can be applied as an alternative.
