CVE Severity Published▾ Status Exploitation Description
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-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-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-2010-1157 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-2007-2449 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-2007-1355 Medium 2007-05-21 Mitigation candidate Working exploit published Multiple cross-site scripting (XSS) vulnerabilities in the appdev/sample/web/hello.jsp example application in 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 5.5.23, and 6.0.0 through 6.0.10 allow remote attackers to inject arbitrary web script or HTML via the test parameter and unspecified vectors.
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.
