AI Analysis
Technical Summary
The vulnerability in XWiki Platform's org.xwiki.platform:xwiki-platform-oldcore component involves allocation of resources without limits or throttling (CWE-770). Specifically, REST API endpoints such as /xwiki/rest/wikis/xwiki/spaces/AnnotationCode/pages/AnnotationConfig/objects/AnnotationCode.AnnotationConfig/0/properties return metadata including all available pages without query limits. This behavior can lead to resource exhaustion on servers hosting large wikis. The issue affects versions >= 1.8-rc-1 and < 16.10.16, >= 17.0.0-rc-1 and < 17.4.8, and >= 17.5.0-rc-1 and < 17.10.1. Patches have been released in versions 16.10.16, 17.4.8, and 17.10.1 to address this vulnerability.
Potential Impact
Exploitation of this vulnerability can cause resource exhaustion on the server hosting the XWiki Platform, potentially leading to denial of service conditions. The impact is limited to performance degradation or service unavailability due to excessive resource consumption. There is no indication of privilege escalation, data disclosure, or code execution. No known exploits are reported in the wild.
Mitigation Recommendations
A fix is available and has been released in XWiki Platform versions 16.10.16, 17.4.8, and 17.10.1. Users should upgrade to one of these or later versions to remediate the vulnerability. Since this is not a cloud service, remediation requires applying the official patches. Patch status is confirmed by the vendor advisory embedded in the description.
