The solution: “immediately” patch each affected installation by updating to the latest available version, according to the vendor.
Atlassian fixed a high-severity issue in the FasterXML Jackson Databind code used in some versions of Jira Software Data Center and Server. The bug, tracked as CVE-2020-25649, could allow XML external entity (XXE) attacks.
It’s a good idea to update both Confluence and Jira Software to the latest version, according to the collaboration business.
VMware bug CVE-2023-34063. It’s a problem with access control in Aria Automation versions prior to 8.16. VMware Cloud Foundation may be affected.
The bug has a high rating of 9.9 CVSS. VMware warns that if it is successfully exploited, it can allow unauthorized access to remote organizations and workflows. Luckily this one also has a fix, so upgrade to VMware Aria Automation 8.16, and then apply the patch.
As the virtualization giant notes: “The only supported upgrade path after applying the patch is to version 8.16. VMware strongly recommends this version. If you upgrade to an intermediate version, the vulnerability will be reintroduced, requiring an additional round of patching.”
VMware has no reports of exploitation so far. However, it is likely that potential attackers are already searching for vulnerable installations. Therefore, it is important to apply the fix promptly, before the software vendor is required to update its advisory.
