CVE-2020-11996 6 Apache, Canonical, Debian and 3 more 8 Tomcat, Ubuntu Linux, Debian Linux and 5 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
A specially crafted sequence of HTTP/2 requests sent to Apache Tomcat 10.0.0-M1 to 10.0.0-M5, 9.0.0.M1 to 9.0.35 and 8.5.0 to 8.5.55 could trigger high CPU usage for several seconds. If a sufficient number of such requests were made on concurrent HTTP/2 connections, the server could become unresponsive.
CVE-2020-11994 2 Apache, Oracle 4 Camel, Communications Diameter Signaling Router, Enterprise Manager Base Platform and 1 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
Server-Side Template Injection and arbitrary file disclosure on Camel templating components
CVE-2020-11993 7 Apache, Canonical, Debian and 4 more 13 Http Server, Ubuntu Linux, Debian Linux and 10 more 2023-11-07 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-2020-11989 1 Apache 1 Shiro 2023-11-07 7.5 HIGH 9.8 CRITICAL
Apache Shiro before 1.5.3, when using Apache Shiro with Spring dynamic controllers, a specially crafted request may cause an authentication bypass.
CVE-2020-11988 2 Apache, Fedoraproject 2 Xmlgraphics Commons, Fedora 2023-11-07 6.4 MEDIUM 8.2 HIGH
Apache XmlGraphics Commons 2.4 and earlier is vulnerable to server-side request forgery, caused by improper input validation by the XMPParser. By using a specially-crafted argument, an attacker could exploit this vulnerability to cause the underlying server to make arbitrary GET requests. Users should upgrade to 2.6 or later.
CVE-2020-11986 1 Apache 1 Netbeans 2023-11-07 7.5 HIGH 9.8 CRITICAL
To be able to analyze gradle projects, the build scripts need to be executed. Apache NetBeans follows this pattern. This causes the code of the build script to be invoked at load time of the project. Apache NetBeans up to and including 12.0 did not request consent from the user for the analysis of the project at load time. This in turn will run potentially malicious code, from an external source, without the consent of the user.
CVE-2020-11985 1 Apache 1 Http Server 2023-11-07 4.3 MEDIUM 5.3 MEDIUM
IP address spoofing when proxying using mod_remoteip and mod_rewrite For configurations using proxying with mod_remoteip and certain mod_rewrite rules, an attacker could spoof their IP address for logging and PHP scripts. Note this issue was fixed in Apache HTTP Server 2.4.24 but was retrospectively allocated a low severity CVE in 2020.
CVE-2020-11984 7 Apache, Canonical, Debian and 4 more 13 Http Server, Ubuntu Linux, Debian Linux and 10 more 2023-11-07 7.5 HIGH 9.8 CRITICAL
Apache HTTP server 2.4.32 to 2.4.44 mod_proxy_uwsgi info disclosure and possible RCE
CVE-2020-11979 4 Apache, Fedoraproject, Gradle and 1 more 37 Ant, Fedora, Gradle and 34 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
As mitigation for CVE-2020-1945 Apache Ant 1.10.8 changed the permissions of temporary files it created so that only the current user was allowed to access them. Unfortunately the fixcrlf task deleted the temporary file and created a new one without said protection, effectively nullifying the effort. This would still allow an attacker to inject modified source files into the build process.
CVE-2020-11976 1 Apache 2 Fortress, Wicket 2023-11-07 5.0 MEDIUM 7.5 HIGH
By crafting a special URL it is possible to make Wicket deliver unprocessed HTML templates. This would allow an attacker to see possibly sensitive information inside a HTML template that is usually removed during rendering. Affected are Apache Wicket versions 7.16.0, 8.8.0 and 9.0.0-M5
CVE-2020-11975 1 Apache 1 Unomi 2023-11-07 10.0 HIGH 9.8 CRITICAL
Apache Unomi allows conditions to use OGNL scripting which offers the possibility to call static Java classes from the JDK that could execute code with the permission level of the running Java process.
CVE-2020-11971 2 Apache, Oracle 5 Camel, Communications Diameter Intelligence Hub, Communications Diameter Signaling Router and 2 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
Apache Camel's JMX is vulnerable to Rebind Flaw. Apache Camel 2.22.x, 2.23.x, 2.24.x, 2.25.x, 3.0.0 up to 3.1.0 is affected. Users should upgrade to 3.2.0.
CVE-2020-11969 1 Apache 1 Tomee 2023-11-07 6.8 MEDIUM 9.8 CRITICAL
If Apache TomEE is configured to use the embedded ActiveMQ broker, and the broker URI includes the useJMX=true parameter, a JMX port is opened on TCP port 1099, which does not include authentication. This affects Apache TomEE 8.0.0-M1 - 8.0.1, Apache TomEE 7.1.0 - 7.1.2, Apache TomEE 7.0.0-M1 - 7.0.7, Apache TomEE 1.0.0 - 1.7.5.
CVE-2019-9518 11 Apache, Apple, Canonical and 8 more 20 Traffic Server, Mac Os X, Swiftnio and 17 more 2023-11-07 7.8 HIGH 7.5 HIGH
Some HTTP/2 implementations are vulnerable to a flood of empty frames, potentially leading to a denial of service. The attacker sends a stream of frames with an empty payload and without the end-of-stream flag. These frames can be DATA, HEADERS, CONTINUATION and/or PUSH_PROMISE. The peer spends time processing each frame disproportionate to attack bandwidth. This can consume excess CPU.
CVE-2019-9517 12 Apache, Apple, Canonical and 9 more 25 Http Server, Traffic Server, Mac Os X and 22 more 2023-11-07 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-2019-9516 12 Apache, Apple, Canonical and 9 more 21 Traffic Server, Mac Os X, Swiftnio and 18 more 2023-11-07 6.8 MEDIUM 6.5 MEDIUM
Some HTTP/2 implementations are vulnerable to a header leak, potentially leading to a denial of service. The attacker sends a stream of headers with a 0-length header name and 0-length header value, optionally Huffman encoded into 1-byte or greater headers. Some implementations allocate memory for these headers and keep the allocation alive until the session dies. This can consume excess memory.
CVE-2019-9515 12 Apache, Apple, Canonical and 9 more 24 Traffic Server, Mac Os X, Swiftnio and 21 more 2023-11-07 7.8 HIGH 7.5 HIGH
Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service. The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost equivalent in behavior to a ping. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.
CVE-2019-9514 13 Apache, Apple, Canonical and 10 more 30 Traffic Server, Mac Os X, Swiftnio and 27 more 2023-11-07 7.8 HIGH 7.5 HIGH
Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both.
CVE-2019-9513 12 Apache, Apple, Canonical and 9 more 22 Traffic Server, Mac Os X, Swiftnio and 19 more 2023-11-07 7.8 HIGH 7.5 HIGH
Some HTTP/2 implementations are vulnerable to resource loops, potentially leading to a denial of service. The attacker creates multiple request streams and continually shuffles the priority of the streams in a way that causes substantial churn to the priority tree. This can consume excess CPU.
CVE-2019-9512 5 Apache, Apple, Canonical and 2 more 6 Traffic Server, Mac Os X, Swiftnio and 3 more 2023-11-07 7.8 HIGH 7.5 HIGH
Some HTTP/2 implementations are vulnerable to ping floods, potentially leading to a denial of service. The attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.
