It is possible to define an entity by providing a substitution string in the form of a URI. The XML parser can access the contents of this URI and embed these contents back into the XML document for further processing.\nBy submitting an XML file that defines an external entity with a file:\u002F\u002F URI, an attacker can cause the processing application to read the contents of a local file. For example, a URI such as \"file:\u002F\u002F\u002Fc:\u002Fwinnt\u002Fwin.ini\" designates (in Windows) the file C:\\Winnt\\win.ini, or file:\u002F\u002F\u002Fetc\u002Fpasswd designates the password file in Unix-based systems. Using URIs with other schemes such as http:\u002F\u002F, the attacker can force the application to make outgoing requests to servers that the attacker cannot reach directly, which can be used to bypass firewall restrictions or hide the source of attacks such as port scanning.\nOnce the content of the URI is read, it is fed back into the application that is processing the XML. This application may echo back the data (e.g. in an error message), thereby exposing the file contents.","Draft","Base","Simple",{"id":74,"name":75,"description":76,"extendedDescription":77,"status":70,"abstraction":71,"structure":72},"CWE-776","Improper Restriction of Recursive Entity References in DTDs ('XML Entity Expansion')","The product uses XML documents and allows their structure to be defined with a Document Type Definition (DTD), but it does not properly control the number of recursive definitions of entities.","If the DTD contains a large number of nested or recursive entities, this can lead to explosive growth of data when parsed, causing a denial of service.",2,false,[],{"title":82,"metaDescription":83,"keywords":84,"canonicalUrl":85,"structuredData":86},"What is CVE-2023-20052?
