Uncaught Exception

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

Affected versions of this package are vulnerable to Uncaught Exception due to the custom Jakarta Authentication ServerAuthContext component which may throw an exception during the authentication process without setting an HTTP status to indicate failure. An attacker can gain unauthorized access by exploiting this unchecked error condition.

Note:

This is only exploitable if Tomcat is configured to use a custom Jakarta Authentication ServerAuthContext component that behaves in this way. According to the maintainers, no such cases are known.

How to fix Uncaught Exception?

Upgrade org.apache.tomcat.embed:tomcat-embed-core to version 9.0.96, 10.1.31, 11.0.0 or higher.

[9.0.0.M1,9.0.96) [10.1.0-M1,10.1.31) [11.0.0-M1,11.0.0)
  • M
Inadequate Encryption Strength

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

Affected versions of this package are vulnerable to Inadequate Encryption Strength due to incorrect recycling of the request and response used by HTTP/2 requests. An attacker can cause a mix-up of requests and/or responses between users by exploiting the reuse of incorrect objects.

How to fix Inadequate Encryption Strength?

Upgrade org.apache.tomcat.embed:tomcat-embed-core to version 9.0.96, 10.1.31, 11.0.0 or higher.

[9.0.93,9.0.96) [10.1.28,10.1.31) [11.0.0-M24,11.0.0)

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) due to an incomplete fix for CVE-2023-24998. If non-default HTTP connector settings were used such that the maxParameterCount could be reached using query string parameters and a request was submitted that supplied exactly maxParameterCount parameters in the query string, the limit on uploaded request parts could be bypassed.

How to fix Denial of Service (DoS)?

Upgrade org.apache.tomcat.embed:tomcat-embed-core to version 8.5.88, 9.0.74, 10.1.8, 11.0.0-M5 or higher.

[8.5.85,8.5.88) [9.0.71,9.0.74) [10.1.5,10.1.8) [11.0.0-M2,11.0.0-M5)

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)
