CyberRota Analysis
AI-GeneratedCentreStack versions prior to 17.4 are vulnerable to an XML external entity (XXE) injection, allowing unauthenticated attackers to exfiltrate sensitive files by exploiting the SharePoint storage configuration handler. This vulnerability can lead to the exposure of critical data, including database credentials and cryptographic keys, through crafted requests to the StorageConfig endpoint. Organizations using affected versions of CentreStack should prioritize patching to mitigate the risk of unauthorized data access.
Original NVD Description
CentreStack before 17.4 contains an XML external entity (XXE) injection vulnerability that allows unauthenticated attackers to exfiltrate arbitrary files by supplying a malicious URL to the SharePoint storage configuration handler. Attackers can send a crafted request to the unauthenticated StorageConfig endpoint causing the server to fetch and parse attacker-controlled XML containing external DTD references, resulting in out-of-band file exfiltration of sensitive files such as Web.config, which may contain database credentials and cryptographic key material.
