A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.0.0 prior to 2.9.10.1, 2.8.11.5, and 2.6.7.3. When Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint and the service has the apache-log4j-extra (version 1.2.x) jar in the classpath, and an attacker can provide a JNDI service to access, it is possible to make the service execute a malicious payload.

A Polymorphic Typing issue was discovered in FasterXML jackson-databind before 2.9.10, 2.8.11.5, and 2.6.7.3. It is related to com.zaxxer.hikari.HikariDataSource. This is a different vulnerability than CVE-2019-14540.

A flaw was discovered in FasterXML jackson-databind, where it would permit polymorphic deserialization of malicious objects using the ehcache and logback JNDI gadgets when used in conjunction with polymorphic type handling methods such as enableDefaultTyping() or when @JsonTypeInfo is using Id.CLASS or Id.MINIMALCLASS or in any other way which ObjectMapper.readValue might instantiate objects from unsafe sources. An attacker could use this flaw to execute arbitrary code.

A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.0.0 prior to 2.9.10.1, 2.8.11.5, and 2.6.7.3. When Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint and the service has the p6spy (3.8.6) jar in the classpath, and an attacker can find an RMI service endpoint to access, it is possible to make the service execute a malicious payload. This issue exists because of com.p6spy.engine.spy.P6DataSource mishandling.

Remedy

The following conditions are needed for an exploit, we recommend avoiding all if possible * Deserialization from sources you do not control * `enableDefaultTyping()` * `@JsonTypeInfo using `id.CLASS` or `id.MINIMAL_CLASS`

A HTTP smuggling flaw was found in HttpObjectDecoder.java in Netty in versions prior to version 4.1.44. HTTP headers with an invalid fold, in this case CRLF (carriage return, line feed) without being followed by SP (space) or HTAB (horizontal tab), result in situations where headers can be misread. Data integrity is the highest threat with this vulnerability.

1 / 5

Remedy

* Use HTTP/2 instead (clear boundaries between requests) * Disable reuse of backend connections eg. ```http-reuse never``` in HAProxy or whatever equivalent LB settings

A flaw was found in Netty before version 4.1.44, where it accepted multiple Content-Length headers and also accepted both Transfer-Encoding, as well as Content-Length headers where it should reject the message under such circumstances. In circumstances where Netty is used in the context of a server, it could result in a viable HTTP smuggling vulnerability.
