CVE-2017-5645 4 Apache, Netapp, Oracle and 1 more 86 Log4j, Oncommand Api Services, Oncommand Insight and 83 more 2026-10-08 9.8 Critical
In Apache Log4j 2.x before 2.8.2, when using the TCP socket server or UDP socket server to receive serialized log events from another application, a specially crafted binary payload can be sent that, when deserialized, can execute arbitrary code.
CVE-2016-6797 6 Apache, Canonical, Debian and 3 more 15 Tomcat, Ubuntu Linux, Debian Linux and 12 more 2026-10-08 7.5 High
The ResourceLinkFactory implementation in Apache Tomcat 9.0.0.M1 to 9.0.0.M9, 8.5.0 to 8.5.4, 8.0.0.RC1 to 8.0.36, 7.0.0 to 7.0.70 and 6.0.0 to 6.0.45 did not limit web application access to global JNDI resources to those resources explicitly linked to the web application. Therefore, it was possible for a web application to access any global JNDI resource whether an explicit ResourceLink had been configured or not.
CVE-2016-6796 6 Apache, Canonical, Debian and 3 more 16 Tomcat, Ubuntu Linux, Debian Linux and 13 more 2026-10-08 7.5 High
A malicious web application running on Apache Tomcat 9.0.0.M1 to 9.0.0.M9, 8.5.0 to 8.5.4, 8.0.0.RC1 to 8.0.36, 7.0.0 to 7.0.70 and 6.0.0 to 6.0.45 was able to bypass a configured SecurityManager via manipulation of the configuration parameters for the JSP Servlet.
CVE-2016-5018 6 Apache, Canonical, Debian and 3 more 16 Tomcat, Ubuntu Linux, Debian Linux and 13 more 2026-10-08 9.1 Critical
In Apache Tomcat 9.0.0.M1 to 9.0.0.M9, 8.5.0 to 8.5.4, 8.0.0.RC1 to 8.0.36, 7.0.0 to 7.0.70 and 6.0.0 to 6.0.45 a malicious web application was able to bypass a configured SecurityManager via a Tomcat utility method that was accessible to web applications.
CVE-2016-0762 6 Apache, Canonical, Debian and 3 more 16 Tomcat, Ubuntu Linux, Debian Linux and 13 more 2026-10-08 5.9 Medium
The Realm implementations in Apache Tomcat versions 9.0.0.M1 to 9.0.0.M9, 8.5.0 to 8.5.4, 8.0.0.RC1 to 8.0.36, 7.0.0 to 7.0.70 and 6.0.0 to 6.0.45 did not process the supplied password if the supplied user name did not exist. This made a timing attack possible to determine valid user names. Note that the default configuration includes the LockOutRealm which makes exploitation of this vulnerability harder.
CVE-2021-30640 4 Apache, Debian, Oracle and 1 more 10 Tomcat, Debian Linux, Communications Cloud Native Core Policy and 7 more 2026-10-08 6.5 Medium
A vulnerability in the JNDI Realm of Apache Tomcat allows an attacker to authenticate using variations of a valid user name and/or to bypass some of the protection provided by the LockOut Realm. This issue affects Apache Tomcat 10.0.0-M1 to 10.0.5; 9.0.0.M1 to 9.0.45; 8.5.0 to 8.5.65.
CVE-2021-25329 4 Apache, Debian, Oracle and 1 more 15 Tomcat, Debian Linux, Agile Product Lifecycle Management and 12 more 2026-10-08 7.0 High
The fix for CVE-2020-9484 was incomplete. When using Apache Tomcat 10.0.0-M1 to 10.0.0, 9.0.0.M1 to 9.0.41, 8.5.0 to 8.5.61 or 7.0.0. to 7.0.107 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.
CVE-2021-24122 4 Apache, Debian, Oracle and 1 more 6 Tomcat, Debian Linux, Agile Product Lifecycle Management and 3 more 2026-10-08 5.9 Medium
When serving resources from a network location using the NTFS file system, Apache Tomcat versions 10.0.0-M1 to 10.0.0-M9, 9.0.0.M1 to 9.0.39, 8.5.0 to 8.5.59 and 7.0.0 to 7.0.106 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.
CVE-2020-9484 8 Apache, Canonical, Debian and 5 more 30 Tomcat, Ubuntu Linux, Debian Linux and 27 more 2026-10-08 7.0 High
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-2020-1935 7 Apache, Canonical, Debian and 4 more 25 Tomcat, Ubuntu Linux, Debian Linux and 22 more 2026-10-08 4.8 Medium
In Apache Tomcat 9.0.0.M1 to 9.0.30, 8.5.0 to 8.5.50 and 7.0.0 to 7.0.99 the HTTP header parsing code used an approach to end-of-line parsing that allowed some invalid HTTP headers to be parsed as valid. This led to a possibility of HTTP Request Smuggling if Tomcat was located behind a reverse proxy that incorrectly handled the invalid Transfer-Encoding header in a particular manner. Such a reverse proxy is considered unlikely.
CVE-2020-13935 8 Apache, Canonical, Debian and 5 more 23 Tomcat, Ubuntu Linux, Debian Linux and 20 more 2026-10-08 7.5 High
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-2019-17563 6 Apache, Canonical, Debian and 3 more 14 Tomcat, Ubuntu Linux, Debian Linux and 11 more 2026-10-08 7.5 High
When using FORM authentication with Apache Tomcat 9.0.0.M1 to 9.0.29, 8.5.0 to 8.5.49 and 7.0.0 to 7.0.98 there was a narrow window where an attacker could perform a session fixation attack. The window was considered too narrow for an exploit to be practical but, erring on the side of caution, this issue has been treated as a security vulnerability.
CVE-2019-12418 7 Apache, Canonical, Debian and 4 more 7 Tomcat, Ubuntu Linux, Debian Linux and 4 more 2026-10-08 7.0 High
When Apache Tomcat 9.0.0.M1 to 9.0.28, 8.5.0 to 8.5.47, 7.0.0 and 7.0.97 is configured with the JMX Remote Lifecycle Listener, a local attacker without access to the Tomcat process or configuration files is able to manipulate the RMI registry to perform a man-in-the-middle attack to capture user names and passwords used to access the JMX interface. The attacker can then use these credentials to access the JMX interface and gain complete control over the Tomcat instance.
CVE-2016-3092 5 Apache, Canonical, Debian and 2 more 9 Commons Fileupload, Tomcat, Ubuntu Linux and 6 more 2026-10-07 7.5 High
The MultipartStream class in Apache Commons Fileupload before 1.3.2, as used in Apache Tomcat 7.x before 7.0.70, 8.x before 8.0.36, 8.5.x before 8.5.3, and 9.x before 9.0.0.M7 and other products, allows remote attackers to cause a denial of service (CPU consumption) via a long boundary string.
CVE-2014-0050 3 Apache, Oracle, Redhat 16 Commons Fileupload, Tomcat, Retail Applications and 13 more 2026-10-07 7.5 High
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-2017-12617 6 Apache, Canonical, Debian and 3 more 60 Tomcat, Ubuntu Linux, Debian Linux and 57 more 2026-08-25 8.1 High
When running Apache Tomcat versions 9.0.0.M1 to 9.0.0, 8.5.0 to 8.5.22, 8.0.0.RC1 to 8.0.46 and 7.0.0 to 7.0.81 with HTTP PUTs enabled (e.g. via setting the readonly initialisation parameter of the Default servlet to false) it was possible to upload a JSP file to the server via a specially crafted request. This JSP could then be requested and any code it contained would be executed by the server.
CVE-2021-25122 4 Apache, Debian, Oracle and 1 more 15 Tomcat, Debian Linux, Agile Product Lifecycle Management and 12 more 2026-08-25 7.5 High
When responding to new h2c connection requests, Apache Tomcat versions 10.0.0-M1 to 10.0.0, 9.0.0.M1 to 9.0.41 and 8.5.0 to 8.5.61 could duplicate request headers and a limited amount of request body from one request to another meaning user A and user B could both see the results of user A's request.
CVE-2026-76166 1 Redhat 7 Jboss Enterprise Application Platform, Jboss Enterprise Application Platform Expansion Pack, Jboss Enterprise Web Server and 4 more 2026-08-21 4.3 Medium
A flaw was found in mod_cluster's AdvertiseListenerImpl (org.jboss.modcluster core module). A single crafted UDP multicast datagram with a valid HTTP status line and a "Server:" header but without the "Date:", "Digest:", and "Sequence:" headers triggers a NullPointerException in verifyDigest() that is not caught by the worker thread's exception handler. This causes the advertise listener thread to terminate permanently. The failure is silent (isListening() continues to return true) and persists until the node is restarted. The crash occurs before the AdvertiseSecurityKey comparison, so deployments with a configured security key are still affected.
CVE-2023-44487 33 Akka, Amazon, Apache and 30 more 378 Http Server, Opensearch Data Prepper, Apisix and 375 more 2026-08-11 7.5 High
The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023.
CVE-2016-2183 6 Cisco, Nodejs, Openssl and 3 more 14 Content Security Management Appliance, Node.js, Openssl and 11 more 2026-05-29 7.5 High
The DES and Triple DES ciphers, as used in the TLS, SSH, and IPSec protocols and other protocols and products, have a birthday bound of approximately four billion blocks, which makes it easier for remote attackers to obtain cleartext data via a birthday attack against a long-duration encrypted session, as demonstrated by an HTTPS session using Triple DES in CBC mode, aka a "Sweet32" attack.
