|---|---|---|---|---|---|
| CVE-2020-9490 | 7 Apache, Canonical, Debian and 4 more | 25 Http Server, Ubuntu Linux, Debian Linux and 22 more | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| Apache HTTP Server versions 2.4.20 to 2.4.43. A specially crafted value for the 'Cache-Digest' header in a HTTP/2 request would result in a crash when the server actually tries to HTTP/2 PUSH a resource afterwards. Configuring the HTTP/2 feature via "H2Push off" will mitigate this vulnerability for unpatched servers. | |||||
| CVE-2020-9484 | 7 Apache, Canonical, Debian and 4 more | 26 Tomcat, Ubuntu Linux, Debian Linux and 23 more | 2024-11-21 | 4.4 MEDIUM | 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-2020-35452 | 4 Apache, Debian, Fedoraproject and 1 more | 6 Http Server, Debian Linux, Fedora and 3 more | 2024-11-21 | 6.8 MEDIUM | 7.3 HIGH |
| Apache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted Digest nonce can cause a stack overflow in mod_auth_digest. There is no report of this overflow being exploitable, nor the Apache HTTP Server team could create one, though some particular compiler and/or compilation option might make it possible, with limited consequences anyway due to the size (a single byte) and the value (zero byte) of the overflow | |||||
| CVE-2020-1938 | 7 Apache, Blackberry, Debian and 4 more | 21 Geode, Tomcat, Good Control and 18 more | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
| When using the Apache JServ Protocol (AJP), care must be taken when trusting incoming connections to Apache Tomcat. Tomcat treats AJP connections as having higher trust than, for example, a similar HTTP connection. If such connections are available to an attacker, they can be exploited in ways that may be surprising. In Apache Tomcat 9.0.0.M1 to 9.0.0.30, 8.5.0 to 8.5.50 and 7.0.0 to 7.0.99, Tomcat shipped with an AJP Connector enabled by default that listened on all configured IP addresses. It was expected (and recommended in the security guide) that this Connector would be disabled if not required. This vulnerability report identified a mechanism that allowed: - returning arbitrary files from anywhere in the web application - processing any file in the web application as a JSP Further, if the web application allowed file upload and stored those files within the web application (or the attacker was able to control the content of the web application by some other means) then this, along with the ability to process a file as a JSP, made remote code execution possible. It is important to note that mitigation is only required if an AJP port is accessible to untrusted users. Users wishing to take a defence-in-depth approach and block the vector that permits returning arbitrary files and execution as JSP may upgrade to Apache Tomcat 9.0.31, 8.5.51 or 7.0.100 or later. A number of changes were made to the default AJP Connector configuration in 9.0.31 to harden the default configuration. It is likely that users upgrading to 9.0.31, 8.5.51 or 7.0.100 or later will need to make small changes to their configurations. | |||||
| CVE-2020-1935 | 6 Apache, Canonical, Debian and 3 more | 20 Tomcat, Ubuntu Linux, Debian Linux and 17 more | 2024-11-21 | 5.8 MEDIUM | 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-2020-1934 | 6 Apache, Canonical, Debian and 3 more | 11 Http Server, Ubuntu Linux, Debian Linux and 8 more | 2024-11-21 | 5.0 MEDIUM | 5.3 MEDIUM |
| In Apache HTTP Server 2.4.0 to 2.4.41, mod_proxy_ftp may use uninitialized memory when proxying to a malicious FTP server. | |||||

| In Apache HTTP Server 2.4.0 to 2.4.41, redirects configured with mod_rewrite that were intended to be self-referential might be fooled by encoded newlines and redirect instead to an an unexpected URL within the request URL. | |||||
| CVE-2020-17527 | 4 Apache, Debian, Netapp and 1 more | 12 Tomcat, Debian Linux, Element Plug-in and 9 more | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| 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. | |||||
| CVE-2020-13950 | 4 Apache, Debian, Fedoraproject and 1 more | 6 Http Server, Debian Linux, Fedora and 3 more | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| Apache HTTP Server versions 2.4.41 to 2.4.46 mod_proxy_http can be made to crash (NULL pointer dereference) with specially crafted requests using both Content-Length and Transfer-Encoding headers, leading to a Denial of Service | |||||
| CVE-2020-13943 | 3 Apache, Debian, Oracle | 4 Tomcat, Debian Linux, Instantis Enterprisetrack and 1 more | 2024-11-21 | 4.0 MEDIUM | 4.3 MEDIUM |
| If an HTTP/2 client connecting to Apache Tomcat 10.0.0-M1 to 10.0.0-M7, 9.0.0.M1 to 9.0.37 or 8.5.0 to 8.5.57 exceeded the agreed maximum number of concurrent streams for a connection (in violation of the HTTP/2 protocol), it was possible that a subsequent request made on that connection could contain HTTP headers - including HTTP/2 pseudo headers - from a previous request rather than the intended headers. This could lead to users seeing responses for unexpected resources. | |||||
| CVE-2020-13935 | 7 Apache, Canonical, Debian and 4 more | 18 Tomcat, Ubuntu Linux, Debian Linux and 15 more | 2024-11-21 | 5.0 MEDIUM | 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-2020-13934 | 6 Apache, Canonical, Debian and 3 more | 14 Tomcat, Ubuntu Linux, Debian Linux and 11 more | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| An h2c direct connection to Apache Tomcat 10.0.0-M1 to 10.0.0-M6, 9.0.0.M5 to 9.0.36 and 8.5.1 to 8.5.56 did not release the HTTP/1.1 processor after the upgrade to HTTP/2. If a sufficient number of such requests were made, an OutOfMemoryException could occur leading to a denial of service. | |||||
| CVE-2020-11993 | 7 Apache, Canonical, Debian and 4 more | 13 Http Server, Ubuntu Linux, Debian Linux and 10 more | 2024-11-21 | 4.3 MEDIUM | 7.5 HIGH |
| Apache HTTP Server versions 2.4.20 to 2.4.43 When trace/debug was enabled for the HTTP/2 module and on certain traffic edge patterns, logging statements were made on the wrong connection, causing concurrent use of memory pools. Configuring the LogLevel of mod_http2 above "info" will mitigate this vulnerability for unpatched servers. | |||||
| CVE-2020-11987 | 4 Apache, Debian, Fedoraproject and 1 more | 22 Batik, Debian Linux, Fedora and 19 more | 2024-11-21 | 6.4 MEDIUM | 8.2 HIGH |
| Apache Batik 1.13 is vulnerable to server-side request forgery, caused by improper input validation by the NodePickerPanel. By using a specially-crafted argument, an attacker could exploit this vulnerability to cause the underlying server to make arbitrary GET requests. | |||||

| SQLite through 3.31.1 allows attackers to cause a denial of service (segmentation fault) via a malformed window-function query because the AggInfo object's initialization is mishandled. | |||||
| CVE-2019-9517 | 12 Apache, Apple, Canonical and 9 more | 25 Http Server, Traffic Server, Mac Os X and 22 more | 2024-11-21 | 7.8 HIGH | 7.5 HIGH |
| Some HTTP/2 implementations are vulnerable to unconstrained interal data buffering, potentially leading to a denial of service. The attacker opens the HTTP/2 window so the peer can send without constraint; however, they leave the TCP window closed so the peer cannot actually write (many of) the bytes on the wire. The attacker then sends a stream of requests for a large response object. Depending on how the servers queue the responses, this can consume excess memory, CPU, or both. | |||||
| CVE-2019-17569 | 5 Apache, Debian, Netapp and 2 more | 16 Tomcat, Tomee, Debian Linux and 13 more | 2024-11-21 | 5.8 MEDIUM | 4.8 MEDIUM |
| The refactoring present in Apache Tomcat 9.0.28 to 9.0.30, 8.5.48 to 8.5.50 and 7.0.98 to 7.0.99 introduced a regression. The result of the regression was that invalid Transfer-Encoding headers were incorrectly processed leading 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-2019-17567 | 3 Apache, Fedoraproject, Oracle | 5 Http Server, Fedora, Enterprise Manager Ops Center and 2 more | 2024-11-21 | 5.0 MEDIUM | 5.3 MEDIUM |
| Apache HTTP Server versions 2.4.6 to 2.4.46 mod_proxy_wstunnel configured on an URL that is not necessarily Upgraded by the origin server was tunneling the whole connection regardless, thus allowing for subsequent requests on the same connection to pass through with no HTTP validation, authentication or authorization possibly configured. | |||||
| CVE-2019-17566 | 2 Apache, Oracle | 18 Batik, Api Gateway, Business Intelligence and 15 more | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| Apache Batik is vulnerable to server-side request forgery, caused by improper input validation by the "xlink:href" attributes. By using a specially-crafted argument, an attacker could exploit this vulnerability to cause the underlying server to make arbitrary GET requests. | |||||
