| CVE | Severity | Published▾ | Status | Exploitation | Description |
|---|---|---|---|---|---|
| CVE-2026-50229 | Medium | 2026-06-29 | Protected by Waratek | Working exploit published | Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS) vulnerability in the number guess example for Apache Tomcat. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.22, from 10.1.0-M1 through 10.1.55, from 9.0.0.M1 through 9.0.118, from 8.5.0 through 8.5.100, from 7.0.0 through 7.0.109. Other versions that have reached end of support may also be affected. Users are recommended to upgrade to version 11.0.23, 10.1.56 or 9.0.119, which fix the issue. |
| CVE-2025-31650 | High | 2025-04-28 | Protected by Waratek | Working exploit published | Improper Input Validation vulnerability in Apache Tomcat. Incorrect error handling for some invalid HTTP priority headers resulted in incomplete clean-up of the failed request which created a memory leak. A large number of such requests could trigger an OutOfMemoryException resulting in a denial of service. This issue affects Apache Tomcat: from 9.0.76 through 9.0.102, from 10.1.10 through 10.1.39, from 11.0.0-M2 through 11.0.5. The following versions were EOL at the time the CVE was created but are known to be affected: 8.5.90 though 8.5.100. Users are recommended to upgrade to version 9.0.104, 10.1.40 or 11.0.6 which fix the issue. |
| CVE-2023-45648 | Medium | 2023-10-10 | Mitigation candidate | Working exploit published | Improper Input Validation vulnerability in Apache Tomcat.Tomcat from 11.0.0-M1 through 11.0.0-M11, from 10.1.0-M1 through 10.1.13, from 9.0.0-M1 through 9.0.81 and from 8.5.0 through 8.5.93 did not correctly parse HTTP trailer headers. A specially crafted, invalid trailer header could cause Tomcat to treat a single request as multiple requests leading to the possibility of request smuggling when behind a reverse proxy. Older, EOL versions may also be affected. Users are recommended to upgrade to version 11.0.0-M12 onwards, 10.1.14 onwards, 9.0.81 onwards or 8.5.94 onwards, which fix the issue. |
| CVE-2022-29885 | High | 2022-05-12 | Mitigation candidate | Working exploit published | 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. |
| CVE-2020-13935 | High | 2020-07-14 | Mitigation candidate | Working exploit published | The payload length in a WebSocket frame was not correctly validated in Apache Tomcat 10.0.0-M1 to 10.0.0-M6, 9.0.0.M1 to 9.0.36, 8.5.0 to 8.5.56 and 7.0.27 to 7.0.104. Invalid payload lengths could trigger an infinite loop. Multiple requests with invalid payload lengths could lead to a denial of service. |
| CVE-2020-9484 | High | 2020-05-20 | Protected by Waratek | Working exploit published | When using Apache Tomcat versions 10.0.0-M1 to 10.0.0-M4, 9.0.0.M1 to 9.0.34, 8.5.0 to 8.5.54 and 7.0.0 to 7.0.103 if a) an attacker is able to control the contents and name of a file on the server; and b) the server is configured to use the PersistenceManager with a FileStore; and c) 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 d) 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. Note that all of conditions a) to d) must be true for the attack to succeed. |
| CVE-2019-0221 | Medium | 2019-05-28 | Mitigation candidate | Working exploit published | The SSI printenv command in Apache Tomcat 9.0.0.M1 to 9.0.0.17, 8.5.0 to 8.5.39 and 7.0.0 to 7.0.93 echoes user provided data without escaping and is, therefore, vulnerable to XSS. SSI is disabled by default. The printenv command is intended for debugging and is unlikely to be present in a production website. |
| CVE-2016-6816 | High | 2017-03-20 | Protected by Waratek | Working exploit published | The code in Apache Tomcat 9.0.0.M1 to 9.0.0.M11, 8.5.0 to 8.5.6, 8.0.0.RC1 to 8.0.38, 7.0.0 to 7.0.72, and 6.0.0 to 6.0.47 that parsed the HTTP request line permitted invalid characters. This could be exploited, in conjunction with a proxy that also permitted the invalid characters but with a different interpretation, to inject data into the HTTP response. By manipulating the HTTP response the attacker could poison a web-cache, perform an XSS attack and/or obtain sensitive information from requests other then their own. |
| CVE-2014-0050 | High | 2014-04-01 | Mitigation candidate | Working exploit published | MultipartStream.java in Apache Commons FileUpload before 1.3.1, as used in Apache Tomcat, JBoss Web, and other products, allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via a crafted Content-Type header that bypasses a loop's intended exit conditions. |
| CVE-2011-4858 | Medium | 2012-01-05 | Mitigation candidate | Working exploit published | Apache Tomcat before 5.5.35, 6.x before 6.0.35, and 7.x before 7.0.23 computes hash values for form parameters without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted parameters. |
| CVE-2010-4476 | Medium | 2011-02-17 | Mitigation candidate | Working exploit published | The Double.parseDouble method in Java Runtime Environment (JRE) in Oracle Java SE and Java for Business 6 Update 23 and earlier, 5.0 Update 27 and earlier, and 1.4.2_29 and earlier, as used in OpenJDK, Apache, JBossweb, and other products, allows remote attackers to cause a denial of service via a crafted string that triggers an infinite loop of estimations during conversion to a double-precision binary floating-point number, as demonstrated using 2.2250738585072012e-308. |
| CVE-2010-4172 | Medium | 2010-11-26 | Mitigation candidate | Working exploit published | Multiple cross-site scripting (XSS) vulnerabilities in the Manager application in Apache Tomcat 6.0.12 through 6.0.29 and 7.0.0 through 7.0.4 allow remote attackers to inject arbitrary web script or HTML via the (1) orderBy or (2) sort parameter to sessionsList.jsp, or unspecified input to (3) sessionDetail.jsp or (4) java/org/apache/catalina/manager/JspHelper.java, related to use of untrusted web applications. |
| CVE-2010-1157 | Low | 2010-04-23 | Mitigation candidate | Working exploit published | Apache Tomcat 5.5.0 through 5.5.29 and 6.0.0 through 6.0.26 might allow remote attackers to discover the server's hostname or IP address by sending a request for a resource that requires (1) BASIC or (2) DIGEST authentication, and then reading the realm field in the WWW-Authenticate header in the reply. |
| CVE-2009-0580 | Medium | 2009-06-05 | Mitigation candidate | Working exploit published | Apache Tomcat 4.1.0 through 4.1.39, 5.5.0 through 5.5.27, and 6.0.0 through 6.0.18, when FORM authentication is used, allows remote attackers to enumerate valid usernames via requests to /j_security_check with malformed URL encoding of passwords, related to improper error checking in the (1) MemoryRealm, (2) DataSourceRealm, and (3) JDBCRealm authentication realms, as demonstrated by a % (percent) value for the j_password parameter. |
| CVE-2008-2938 | Medium | 2008-08-13 | Protected by Waratek | Working exploit published | Directory traversal vulnerability in Apache Tomcat 4.1.0 through 4.1.37, 5.5.0 through 5.5.26, and 6.0.0 through 6.0.16, when allowLinking and UTF-8 are enabled, allows remote attackers to read arbitrary files via encoded directory traversal sequences in the URI, a different vulnerability than CVE-2008-2370. NOTE: versions earlier than 6.0.18 were reported affected, but the vendor advisory lists 6.0.16 as the last affected version. |
| CVE-2008-2370 | Medium | 2008-08-04 | Protected by Waratek | Working exploit published | Apache Tomcat 4.1.0 through 4.1.37, 5.5.0 through 5.5.26, and 6.0.0 through 6.0.16, when a RequestDispatcher is used, performs path normalization before removing the query string from the URI, which allows remote attackers to conduct directory traversal attacks and read arbitrary files via a .. (dot dot) in a request parameter. |
| CVE-2008-1232 | Medium | 2008-08-04 | Mitigation candidate | Working exploit published | Cross-site scripting (XSS) vulnerability in Apache Tomcat 4.1.0 through 4.1.37, 5.5.0 through 5.5.26, and 6.0.0 through 6.0.16 allows remote attackers to inject arbitrary web script or HTML via a crafted string that is used in the message argument to the HttpServletResponse.sendError method. |
| CVE-2007-5333 | Medium | 2008-02-12 | Mitigation candidate | Working exploit published | Apache Tomcat 6.0.0 through 6.0.14, 5.5.0 through 5.5.25, and 4.1.0 through 4.1.36 does not properly handle (1) double quote (") characters or (2) %5C (encoded backslash) sequences in a cookie value, which might cause sensitive information such as session IDs to be leaked to remote attackers and enable session hijacking attacks. NOTE: this issue exists because of an incomplete fix for CVE-2007-3385. |
| CVE-2007-5461 | Low | 2007-10-15 | Protected by Waratek | Working exploit published | Absolute path traversal vulnerability in Apache Tomcat 4.0.0 through 4.0.6, 4.1.0, 5.0.0, 5.5.0 through 5.5.25, and 6.0.0 through 6.0.14, under certain configurations, allows remote authenticated users to read arbitrary files via a WebDAV write request that specifies an entity with a SYSTEM tag. |
| CVE-2007-3382 | Medium | 2007-08-14 | Mitigation candidate | Working exploit published | Apache Tomcat 6.0.0 to 6.0.13, 5.5.0 to 5.5.24, 5.0.0 to 5.0.30, 4.1.0 to 4.1.36, and 3.3 to 3.3.2 treats single quotes ("'") as delimiters in cookies, which might cause sensitive information such as session IDs to be leaked and allow remote attackers to conduct session hijacking attacks. |
| CVE-2007-2449 | Medium | 2007-06-14 | Mitigation candidate | Working exploit published | Multiple cross-site scripting (XSS) vulnerabilities in certain JSP files in the examples web application in Apache Tomcat 4.0.0 through 4.0.6, 4.1.0 through 4.1.36, 5.0.0 through 5.0.30, 5.5.0 through 5.5.24, and 6.0.0 through 6.0.13 allow remote attackers to inject arbitrary web script or HTML via the portion of the URI after the ';' character, as demonstrated by a URI containing a "snp/snoop.jsp;" sequence. |
| CVE-2006-7196 | Medium | 2007-05-10 | Mitigation candidate | Working exploit published | Cross-site scripting (XSS) vulnerability in the calendar application example in Apache Tomcat 4.0.0 through 4.0.6, 4.1.0 through 4.1.31, 5.0.0 through 5.0.30, and 5.5.0 through 5.5.15 allows remote attackers to inject arbitrary web script or HTML via the time parameter to cal2.jsp and possibly unspecified other vectors. NOTE: this may be related to CVE-2006-0254.1. |
| CVE-2006-3835 | Medium | 2006-07-25 | Mitigation candidate | Working exploit published | Apache Tomcat 5 before 5.5.17 allows remote attackers to list directories via a semicolon (;) preceding a filename with a mapped extension, as demonstrated by URLs ending with /;index.jsp and /;help.do. |
| CVE-2005-4703 | Medium | 2005-12-31 | Mitigation candidate | Working exploit published | Apache Tomcat 4.0.3, when running on Windows, allows remote attackers to obtain sensitive information via a request for a file that contains an MS-DOS device name such as lpt9, which leaks the pathname in an error message, as demonstrated by lpt9.xtp using Nikto. |
| CVE-2003-0866 | Medium | 2003-11-17 | Mitigation candidate | Working exploit published | The Catalina org.apache.catalina.connector.http package in Tomcat 4.0.x up to 4.0.3 allows remote attackers to cause a denial of service via several requests that do not follow the HTTP protocol, which causes Tomcat to reject later requests. |
| CVE-2002-1567 | Medium | 2003-10-06 | Mitigation candidate | Working exploit published | Cross-site scripting (XSS) vulnerability in Apache Tomcat 4.1 allows remote attackers to execute arbitrary web script and steal cookies via a URL with encoded newlines followed by a request to a .jsp file whose name contains the script. |
| CVE-2003-0042 | Medium | 2003-02-07 | Protected by Waratek | Working exploit published | Jakarta Tomcat before 3.3.1a, when used with JDK 1.3.1 or earlier, allows remote attackers to list directories even with an index.html or other file present, or obtain unprocessed source code for a JSP file, via a URL containing a null character. |
| CVE-2002-2272 | High | 2002-12-31 | Mitigation candidate | Working exploit published | Tomcat 4.0 through 4.1.12, using mod_jk 1.2.1 module on Apache 1.3 through 1.3.27, allows remote attackers to cause a denial of service (desynchronized communications) via an HTTP GET request with a Transfer-Encoding chunked field with invalid values. |
| CVE-2002-2006 | Medium | 2002-12-31 | Mitigation candidate | Working exploit published | The default installation of Apache Tomcat 4.0 through 4.1 and 3.0 through 3.3.1 allows remote attackers to obtain the installation path and other sensitive system information via the (1) SnoopServlet or (2) TroubleShooter example servlets. |
| CVE-2002-1148 | Medium | 2002-10-11 | Mitigation candidate | Working exploit published | The default servlet (org.apache.catalina.servlets.DefaultServlet) in Tomcat 4.0.4 and 4.1.10 and earlier allows remote attackers to read source code for server files via a direct request to the servlet. |
| CVE-2001-0590 | Medium | 2001-08-02 | Mitigation candidate | Working exploit published | Apache Software Foundation Tomcat Servlet prior to 3.2.2 allows a remote attacker to read the source code to arbitrary 'jsp' files via a malformed URL request which does not end with an HTTP protocol specification (i.e. HTTP/1.0). |
| CVE-2000-0759 | Medium | 2000-10-20 | Mitigation candidate | Working exploit published | Jakarta Tomcat 3.1 under Apache reveals physical path information when a remote attacker requests a URL that does not exist, which generates an error message that includes the physical path. |
