GHSA-G2VX-F8P2-FQ5G
Vulnerability from github – Published: 2024-11-18 18:30 – Updated: 2024-11-18 18:30A vulnerability in the web UI of Cisco SD-WAN vManage Software could allow an authenticated, remote attacker to gain read and write access to information that is stored on an affected system. The vulnerability is due to improper handling of XML External Entity (XXE) entries when parsing certain XML files. An attacker could exploit this vulnerability by persuading a user to import a crafted XML file with malicious entries. A successful exploit could allow the attacker to read and write files within the affected application.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

This vulnerability allows remote attackers to disclose sensitive information on affected installations of Inductive Automation Ignition. Authentication is required to exploit this vulnerability.
The specific flaw exists within the SimpleXMLReader class. Due to the improper restriction of XML External Entity (XXE) references, a 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 the SYSTEM. Was ZDI-CAN-17571.

Mitigation
Many XML parsers and validators can be configured to disable external entity expansion.
CAPEC-221: Data Serialization External Entities Blowup
This attack takes advantage of the entity replacement property of certain data serialization languages (e.g., XML, YAML, etc.) where the value of the replacement is a URI. A well-crafted file could have the entity refer to a URI that consumes a large amount of resources to create a denial of service condition. This can cause the system to either freeze, crash, or execute arbitrary code depending on the URI.
