CVSS v3.1 |
| Apache Tomcat through 7.0.x allows remote attackers to cause a denial of service (daemon outage) via partial HTTP requests, as demonstrated by Slowloris. |
| java/org/apache/catalina/core/AsyncContextImpl.java in Apache Tomcat 7.x before 7.0.40 does not properly handle the throwing of a RuntimeException in an AsyncListener in an application, which allows context-dependent attackers to obtain sensitive request information intended for other applications in opportunistic circumstances via an application that records the requests that it processes. |
| Apache Tomcat 6.0.30 through 6.0.33 and 7.x before 7.0.22 does not properly perform certain caching and recycling operations involving request objects, which allows remote attackers to obtain unintended read access to IP address and HTTP header information in opportunistic circumstances by reading TCP data. |
| Apache Tomcat 5.5.x before 5.5.35, 6.x before 6.0.34, and 7.x before 7.0.23 uses an inefficient approach for handling parameters, which allows remote attackers to cause a denial of service (CPU consumption) via a request that contains many parameters and parameter values, a different vulnerability than CVE-2011-4858. |
| The HTTP Digest Access Authentication implementation in Apache Tomcat 5.5.x before 5.5.34, 6.x before 6.0.33, and 7.x before 7.0.12 does not check qop values, which might allow remote attackers to bypass intended integrity-protection requirements via a qop=auth value, a different vulnerability than CVE-2011-1184. |
| The HTTP Digest Access Authentication implementation in Apache Tomcat 5.5.x before 5.5.34, 6.x before 6.0.33, and 7.x before 7.0.12 does not check realm values, which might allow remote attackers to bypass intended access restrictions by leveraging the availability of a protection space with weaker authentication or authorization requirements, a different vulnerability than CVE-2011-1184. |
| org/apache/catalina/filters/CsrfPreventionFilter.java in Apache Tomcat 6.x before 6.0.36 and 7.x before 7.0.32 allows remote attackers to bypass the cross-site request forgery (CSRF) protection mechanism via a request that lacks a session identifier. |
| org/apache/catalina/realm/RealmBase.java in Apache Tomcat 6.x before 6.0.36 and 7.x before 7.0.30, when FORM authentication is used, allows remote attackers to bypass security-constraint checks by leveraging a previous setUserPrincipal call and then placing /j_security_check at the end of a URI. |
| Apache Tomcat 6.x before 6.0.37 and 7.x before 7.0.30 does not properly handle chunk extensions in chunked transfer coding, which allows remote attackers to cause a denial of service by streaming data. |
| java/org/apache/coyote/http11/InternalNioInputBuffer.java in the HTTP NIO connector in Apache Tomcat 6.x before 6.0.36 and 7.x before 7.0.28 does not properly restrict the request-header size, which allows remote attackers to cause a denial of service (memory consumption) via a large amount of header data. |
| org/apache/catalina/core/DefaultInstanceManager.java in Apache Tomcat 7.x before 7.0.22 does not properly restrict ContainerServlets in the Manager application, which allows local users to gain privileges by using an untrusted web application to access the Manager application's functionality. |
| The fix for CVE-2023-24998 was incomplete for Apache Tomcat 11.0.0-M2 to 11.0.0-M4, 10.1.5 to 10.1.7, 9.0.71 to 9.0.73 and 8.5.85 to 8.5.87. 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 for uploaded request parts could be bypassed with the potential for a denial of service to occur. |
| A regression in the fix for bug 66512 in Apache Tomcat 11.0.0-M5, 10.1.8, 9.0.74 and 8.5.88 meant that, if a response did not include any HTTP headers no AJP SEND_HEADERS messare woudl be sent for the response which in turn meant that at least one AJP proxy (mod_proxy_ajp) would use the response headers from the previous request leading to an information leak. |
| While investigating bug 64830 it was discovered that Apache Tomcat 10.0.0-M1 to 10.0.0-M9, 9.0.0-M1 to 9.0.39 and 8.5.0 to 8.5.59 could re-use an HTTP request header value from the previous stream received on an HTTP/2 connection for the request associated with the subsequent stream. While this would most likely lead to an error and the closure of the HTTP/2 connection, it is possible that information could leak between requests. |
| Important: Authentication Bypass CVE-2023-41081
The mod_jk component of Apache Tomcat Connectors in some circumstances, such as when a configuration included "JkOptions +ForwardDirectories" but the configuration did not provide explicit mounts for all possible proxied requests, mod_jk would use an implicit mapping and map the request to the first defined worker. Such an implicit mapping could result in the unintended exposure of the status worker and/or bypass security constraints configured in httpd. As of JK 1.2.49, the implicit mapping functionality has been removed and all mappings must now be via explicit configuration. Only mod_jk is affected by this issue. The ISAPI redirector is not affected.
This issue affects Apache Tomcat Connectors (mod_jk only): from 1.2.0 through 1.2.48.
Users are recommended to upgrade to version 1.2.49, which fixes the issue.

|
| The JsonErrorReportValve in Apache Tomcat 8.5.83, 9.0.40 to 9.0.68 and 10.1.0-M1 to 10.1.1 did not escape the type, message or description values. In some circumstances these are constructed from user provided data and it was therefore possible for users to supply values that invalidated or manipulated the JSON output. |
| In Apache Tomcat 10.1.0-M1 to 10.1.0-M16, 10.0.0-M1 to 10.0.22, 9.0.30 to 9.0.64 and 8.5.50 to 8.5.81 the Form authentication example in the examples web application displayed user provided data without filtering, exposing a XSS vulnerability. |
| The documentation of Apache Tomcat 10.1.0-M1 to 10.1.0-M14, 10.0.0-M1 to 10.0.20, 9.0.13 to 9.0.62 and 8.5.38 to 8.5.78 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. |
| The fix for bug CVE-2020-9484 introduced a time of check, time of use vulnerability into Apache Tomcat 10.1.0-M1 to 10.1.0-M8, 10.0.0-M5 to 10.0.14, 9.0.35 to 9.0.56 and 8.5.55 to 8.5.73 that allowed 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. |
| The fix for bug 63362 present in Apache Tomcat 10.1.0-M1 to 10.1.0-M5, 10.0.0-M1 to 10.0.11, 9.0.40 to 9.0.53 and 8.5.60 to 8.5.71 introduced a memory leak. The object introduced to collect metrics for HTTP upgrade connections was not released for WebSocket connections once the connection was closed. This created a memory leak that, over time, could lead to a denial of service via an OutOfMemoryError. |
