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)
  • H
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.

Access Restriction Bypass

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

Affected versions of this package are vulnerable to Access Restriction Bypass. If the ROOT (default) web application is configured to use FORM authentication then it is possible that a specially crafted URL could be used to trigger a redirect to an URL of the attackers choice.

The vulnerability is limited to the ROOT (default) web application.

How to fix Access Restriction Bypass?

Upgrade org.apache.tomcat.embed:tomcat-embed-core to version 8.5.93, 9.0.80, 10.1.13, 11.0.0-M11 or higher.

[8.5.0,8.5.93) [9.0.0-M1,9.0.80) [10.1.0-M1,10.1.13) [11.0.0-M1,11.0.0-M11)

Unprotected Transport of Credentials

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

Affected versions of this package are vulnerable to Unprotected Transport of Credentials when using the RemoteIpFilter with requests received from a reverse proxy via HTTP, in which the X-Forwarded-Proto header is set to https. Session cookies do not include the secure attribute, so the user agent may transmit the session cookie over an insecure channel.

How to fix Unprotected Transport of Credentials?

Upgrade org.apache.tomcat.embed:tomcat-embed-core to version 8.5.86, 9.0.72, 10.1.6, 11.0.0-M3 or higher.

[8.5.0,8.5.86) [9.0.0-M1,9.0.72) [10.1.0-M1,10.1.6) [11.0.0-M1,11.0.0-M3)
  • M
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 an attacker sends a large number of request parts in a series of uploads or a single multipart upload.

NOTE: After upgrading to the fixed version, the setFileCountMax() must be explicitly set to avoid this vulnerability.

How to fix Denial of Service (DoS)?

Upgrade org.apache.tomcat.embed:tomcat-embed-core to version 8.5.85, 9.0.71, 10.1.5, 11.0.0-M3 or higher.

[8.5.0,8.5.85) [9.0.0-M1,9.0.71) [10.1.0-M1,10.1.5) [11.0.0-M1,11.0.0-M3)

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 such that the JsonErrorReportValve does not escape the type, message or description values. In some circumstances these are constructed from user provided data and it is possible for users to supply values that invalidate or manipulate the JSON output.

How to fix Improper Input Validation?

Upgrade org.apache.tomcat.embed:tomcat-embed-core to version 8.5.84, 9.0.69, 10.1.2 or higher.

HTTP Request Smuggling

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

Affected versions of this package are vulnerable to HTTP Request Smuggling when improper requests containing an invalid Content-Length header are not being properly rejected.

Note: Exploiting this vulnerability is also possible if Tomcat was located behind a reverse proxy that also failed to reject the request with the invalid header.

How to fix HTTP Request Smuggling?

Upgrade org.apache.tomcat.embed:tomcat-embed-core to version 8.5.53, 9.0.68, 10.0.27, 10.1.1 or higher.

[8.5.0,8.5.53) [9.0.0-M1,9.0.68) [10.0.0-M1,10.0.27) [10.1.0-M1,10.1.1)
