Denial of Service (DoS)

org.apache.tomcat.embed:tomcat-embed-core is a Core Tomcat implementation.

Affected versions of this package are vulnerable to Denial of Service (DoS) when processing a crafted HTTP/2 request. If the request exceeded any of the configured limits for headers, the associated HTTP/2 stream was not reset until after all of the headers had been processed.

How to fix Denial of Service (DoS)?

Upgrade org.apache.tomcat.embed:tomcat-embed-core to version 8.5.99, 9.0.86, 10.1.19, 1.0.0-M17 or higher.

Improper Input Validation

org.apache.tomcat.embed:tomcat-embed-core is a Core Tomcat implementation.

Affected versions of this package are vulnerable to Improper Input Validation due to the improper parsing of HTTP trailer headers. An attacker can manipulate the server into treating a single request as multiple requests by sending a trailer header that exceeds the header size limit. This could lead to request smuggling when the server is behind a reverse proxy.

How to fix Improper Input Validation?

Upgrade org.apache.tomcat.embed:tomcat-embed-core to version 8.5.96, 9.0.83, 10.1.16, 11.0.0-M10 or higher.

Incomplete Cleanup

org.apache.tomcat.embed:tomcat-embed-core is a Core Tomcat implementation.

Affected versions of this package are vulnerable to Incomplete Cleanup when recycling various internal objects. An error could cause some parts of the recycling process to be skipped, leading to information leaking from the current request/response to the next. An attacker can gain unauthorised access to sensitive information by exploiting this error.

How to fix Incomplete Cleanup?

Upgrade org.apache.tomcat.embed:tomcat-embed-core to version 8.5.94, 9.0.81, 10.1.14, 11.0.0-M12 or higher.

Improper Input Validation

org.apache.tomcat.embed:tomcat-embed-core is a Core Tomcat implementation.

Affected versions of this package are vulnerable to Improper Input Validation due to the improper handling of HTTP trailer headers. An attacker can manipulate the server into treating a single request as multiple requests by sending a specially crafted, invalid trailer header. This could lead to request smuggling when the server is behind a reverse proxy.

How to fix Improper Input Validation?

Upgrade org.apache.tomcat.embed:tomcat-embed-core to version 8.5.94, 9.0.81, 10.1.14, 11.0.0-M12 or higher.

[8.5.0,8.5.94) [9.0.0-M1,9.0.81) [10.1.0-M1,10.1.14) [11.0.0-M1,11.0.0-M12)

Incomplete Cleanup

org.apache.tomcat.embed:tomcat-embed-core is a Core Tomcat implementation.

Affected versions of this package are vulnerable to Incomplete Cleanup in the internal fork of Commons FileUpload package. An attacker can potentially cause a denial of service on Windows by opening a stream for an uploaded file but failing to close the stream. This results in the file never being deleted from the disk, creating the possibility of an eventual denial of service due to the disk being full.

Note:

This vulnerability is exploitable on Windows operating systems.

How to fix Incomplete Cleanup?

Upgrade org.apache.tomcat.embed:tomcat-embed-core to version 8.5.94, 9.0.81 or higher.

Denial of Service (DoS)

org.apache.tomcat.embed:tomcat-embed-core is a Core Tomcat implementation.

Affected versions of this package are vulnerable to Denial of Service (DoS) in the implementation of the HTTP/2 protocol. An attacker can cause a denial of service (including via DDoS) by rapidly resetting many streams through request cancellation.

How to fix Denial of Service (DoS)?

Upgrade org.apache.tomcat.embed:tomcat-embed-core to version 8.5.94, 9.0.81, 10.1.14, 11.0.0-M12 or higher.
