XPath injection vulnerability in Epic MyChart allows remote attackers to access contents of an XML document containing static display strings, such as field labels, via the topic parameter to help.asp. NOTE: this was originally reported as a SQL injection vulnerability, but this may be inaccurate.
The product does not properly neutralize special elements that are used in XML, allowing attackers to modify the syntax, content, or commands of the XML before it is processed by an end system.
https://cwe.mitre.org/data/definitions/91.html →Open in CWE collection →An attacker can craft special user-controllable input consisting of XPath expressions to inject the XML database and bypass authentication or glean information that they normally would not be able to. XPath Injection enables an attacker to talk directly to the XML database, thus bypassing the application completely. XPath Injection results from the failure of an application to properly sanitize input used as part of dynamic XPath expressions used to query an XML database.
https://capec.mitre.org/data/definitions/83.html →Open in CAPEC collection →An attacker utilizes crafted XML user-controllable input to probe, attack, and inject data into the XML database, using techniques similar to SQL injection. The user-controllable input can allow for unauthorized viewing of data, bypassing authentication or the front-end application for direct XML database access, and possibly altering database information.
