Apache Log4j2 versions 2.0-alpha1 through 2.16.0 (excluding 2.12.3 and 2.3.1) did not protect from uncontrolled recursion from self-referential lookups. This allows an attacker with control over Thread Context Map data to cause a denial of service when a crafted string is interpreted. This issue was fixed in Log4j 2.17.0, 2.12.3, and 2.3.1.

SolarWinds Orion Platform 2018.4 HF3 (NPM 12.4, NetPath 1.1.4) is vulnerable to Information Leakage, because of improper error handling with stack traces, as demonstrated by discovering a full pathname upon a 500 Internal Server Error via the api2/swis/query?lang=en-us&swAlertOnError=false query parameter.

SolarWinds Orion Platform 2018.4 HF3 (NPM 12.4, NetPath 1.1.4) allows Stored HTML Injection by administrators via the Web Console Settings screen.

A vulnerability was found in Hibernate-Validator. The SafeHtml validator annotation fails to properly sanitize payloads consisting of potentially malicious code in HTML comments and instructions. This vulnerability can result in an XSS attack.

In Apache Log4j 2.x before 2.8.2, when using the TCP socket server or UDP socket server to receive serialized log events from another application, a specially crafted binary payload can be sent that, when deserialized, can execute arbitrary code.
