org.apache.tomcat:tomcat-catalina@9.0.34 vulnerabilities

org.apache.tomcat:tomcat-catalina is a Tomcat Servlet Engine Core Classes and Standard implementations.

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.

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

org.apache.tomcat:tomcat-catalina is a Tomcat Servlet Engine Core Classes and Standard implementations.

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.

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

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.

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

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.

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

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.

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

org.apache.tomcat:tomcat-catalina is a Tomcat Servlet Engine Core Classes and Standard implementations.

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.

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

org.apache.tomcat:tomcat-catalina is a Tomcat Servlet Engine Core Classes and Standard implementations.

Affected versions of this package are vulnerable to Information Exposure. due to a concurrency bug that could cause client connections to share an Http11Processor instance resulting in responses, or part responses, to be received by the wrong client.

Upgrade org.apache.tomcat:tomcat-catalina to version 8.5.78, 9.0.62, 10.0.20, 10.1.0-M14 or higher.

org.apache.tomcat:tomcat-catalina is a Tomcat Servlet Engine Core Classes and Standard implementations.

Affected versions of this package are vulnerable to Insufficient Technical Documentation. The documentation for the EncryptInterceptor incorrectly stated it enabled Tomcat clustering to run over an untrusted network. This was not correct. While the EncryptInterceptor does provide confidentiality and integrity protection, it does not protect against all risks associated with running over any untrusted network, particularly DoS risks.

Note: The documentation was updated in version 9.0.63.

Upgrade org.apache.tomcat:tomcat-catalina to version 9.0.63 or higher.

org.apache.tomcat:tomcat-catalina is a Tomcat Servlet Engine Core Classes and Standard implementations.

Affected versions of this package are vulnerable to Privilege Escalation via a time of check, time of use vulnerability that allows a local attacker to perform actions with the privileges of the user that the Tomcat process is using. This issue is only exploitable when Tomcat is configured to persist sessions using the FileStore.

Upgrade org.apache.tomcat:tomcat-catalina to version 8.5.74, 9.0.57, 10.0.15, 10.1.0-M9 or higher.

org.apache.tomcat:tomcat-catalina is a Tomcat Servlet Engine Core Classes and Standard implementations.

Affected versions of this package are vulnerable to Improper Input Validation. Queries made by the JNDI Realm did not always correctly escape parameters. Parameter values could be sourced from user provided data (e.g., user names) as well as configuration data provided by an administrator. In limited circumstances it was possible for users to authenticate using variations of their user name and/or to bypass some of the protection provided by the LockOut Realm.

Upgrade org.apache.tomcat:tomcat-catalina to version 10.0.6, 9.0.46, 8.5.66, 7.0.109 or higher.

Affected versions of this package are vulnerable to Remote Code Execution (RCE). The fix for CVE-2020-9484 was incomplete. When using Apache Tomcat with a configuration edge case that was highly unlikely to be used, the Tomcat instance was still vulnerable to CVE-2020-9494. Note that both the previously published prerequisites for CVE-2020-9484 and the previously published mitigations for CVE-2020-9484 also apply to this issue.

Upgrade org.apache.tomcat:tomcat-catalina to version 10.0.2, 9.0.43, 8.5.63, 7.0.108 or higher.

Affected versions of this package are vulnerable to Information Disclosure. When serving resources from a network location using the NTFS file system, affected versions were susceptible to JSP source code disclosure in some configurations. The root cause was the unexpected behaviour of the JRE API File.getCanonicalPath() which in turn was caused by the inconsistent behaviour of the Windows API (FindFirstFileW) in some circumstances.

Upgrade org.apache.tomcat:tomcat-catalina to version 10.0.0-M10, 9.0.40, 8.5.60, 7.0.107 or higher.

org.apache.tomcat:tomcat-catalina is a Tomcat Servlet Engine Core Classes and Standard implementations.

Affected versions of this package are vulnerable to Remote Code Execution (RCE). If an attacker is able to control the contents and name of a file on the server; and the server is configured to use the PersistenceManager with a FileStore; and the PersistenceManager is configured with sessionAttributeValueClassNameFilter="null" (the default unless a SecurityManager is used) or a sufficiently lax filter to allow the attacker provided object to be deserialized; and the attacker knows the relative file path from the storage location used by FileStore to the file the attacker has control over; then, using a specifically crafted request, the attacker will be able to trigger remote code execution via deserialization of the file under their control.

Upgrade org.apache.tomcat:tomcat-catalina to version 10.0.0-M5, 9.0.35, 8.5.55, 7.0.104 or higher.
