Enhancements and Issues Addressed
The following enhancements and addressed issues are included in this release:
- Updated the PowerPack for Python 3.11 compatibility.
- Improved the security of the PowerPack by implementing secure XML parsing that disables external entity resolutions, thereby preventing XML External Entity (XXE) vulnerabilites.
- Addressed an issue that occurred when upgrading to version 105 of the "Cisco: UCS Manager" PowerPack which caused collection errors for multiple Dynamic Applications. The issues were resolved by replacing the libsxlt library with a lxml Python library for the "Cisco: UCS Service Profile Discovery" Dynamic Application and by implementing minor updates to syntax strings for the remaining affected Dynamic Applications.
