The XML document processed in the GMS ECM URL endpoint is vulnerable to XML external entity (XXE) injection, potentially resulting in the disclosure of sensitive information.
This issue affects GMS: 9.3.4 and earlier versions.
El documento XML procesado en el endpoint URL de GMS ECM es vulnerable a la inyección de entidad externa XML (XXE), lo que podría resultar en la divulgación de información confidencial. Este problema afecta a GMS: 9.3.4 y versiones anteriores.
This vulnerability allows remote attackers to disclose sensitive information on affected installations of SonicWALL GMS Virtual Appliance. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed.
The specific flaw exists within the ECMPolicyRequest class. Due to the improper restriction of XML External Entity (XXE) references, a specially crafted document specifying a URI causes the XML parser to access the URI and embed the contents back into the XML document for further processing. An attacker can leverage this vulnerability to disclose information in the context of root.
