In Apache httpd 2.2.0 to 2.4.29, when generating an HTTP Digest authentication challenge, the nonce sent to prevent reply attacks was not correctly generated using a pseudo-random seed. In a cluster of servers using a common Digest authentication configuration, HTTP requests could be replayed across servers by an attacker without detection.

Improper Authentication vulnerability in TLS origin validation of Apache Traffic Server allows an attacker to create a man in the middle attack. This issue affects Apache Traffic Server 8.0.0 to 8.1.0.

Improper authentication is possible in Apache Traffic Control versions 3.0.0 and 3.0.1 if LDAP is enabled for login in the Traffic Ops API component. Given a username for a user that can be authenticated via LDAP, it is possible to improperly authenticate as that user without that user's correct password.

java/org/apache/catalina/authenticator/FormAuthenticator.java in the form authentication feature in Apache Tomcat 6.0.21 through 6.0.36 and 7.x before 7.0.33 does not properly handle the relationships between authentication requirements and sessions, which allows remote attackers to inject a request into a session by sending this request during completion of the login form, a variant of a session fixation attack.

The default configuration for Apache Qpid 0.20 and earlier, when the federation_tag attribute is enabled, accepts AMQP connections without checking the source user ID, which allows remote attackers to bypass authentication and have other unspecified impact via an AMQP request.

Improper Authentication vulnerability in TLS origin verification of Apache Traffic Server allows for man in the middle attacks. This issue affects Apache Traffic Server 8.0.0 to 8.0.8.

Cross-site scripting (XSS) vulnerability in ecommerce/control/keywordsearch in the Apache Open For Business Project (OFBiz) and Opentaps 0.9.3 allows remote attackers to inject arbitrary web script or HTML via the SEARCH_STRING parameter, a different issue than CVE-2006-6587. NOTE: some of these details are obtained from third party information.

Format string vulnerability in the mod_tcl module 1.0 for Apache 2.x allows context-dependent attackers to execute arbitrary code via format string specifiers that are not properly handled in a set_var function call in (1) tcl_cmds.c and (2) tcl_core.c.

Integer overflow in the ap_proxy_send_fb function in proxy/proxy_util.c in mod_proxy in the Apache HTTP Server before 1.3.42 on 64-bit platforms allows remote origin servers to cause a denial of service (daemon crash) or possibly execute arbitrary code via a large chunk size that triggers a heap-based buffer overflow.

Multiple format string vulnerabilities in (1) neon 0.24.4 and earlier, and other products that use neon including (2) Cadaver, (3) Subversion, and (4) OpenOffice, allow remote malicious WebDAV servers to execute arbitrary code.

Multiple cross-site scripting (XSS) vulnerabilities in the (1) examples and (2) ROOT web applications for Jakarta Tomcat 3.x through 3.3.1a allow remote attackers to insert arbitrary web script or HTML.

Apache OpenOffice opens dBase/DBF documents and shows the contents as spreadsheets. DBF are database files with data organized in fields. When reading DBF data the size of certain fields is not checked: the data is just copied into local variables. A carefully crafted document could overflow the allocated space, leading to the execution of arbitrary code by altering the contents of the program stack. This issue affects Apache OpenOffice up to and including version 4.1.10

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.

From Apache Tika versions 1.7 to 1.17, clients could send carefully crafted headers to tika-server that could be used to inject commands into the command line of the server running tika-server. This vulnerability only affects those running tika-server on a server that is open to untrusted clients. The mitigation is to upgrade to Tika 1.18.

The Apache Xerces-C 3.0.0 to 3.2.3 XML parser contains a use-after-free error triggered during the scanning of external DTDs. This flaw has not been addressed in the maintained version of the library and has no current mitigation other than to disable DTD processing. This can be accomplished via the DOM using a standard parser feature, or via SAX using the XERCES_DISABLE_DTD environment variable.

Apache OpenMeetings 1.0.0 is vulnerable to Cross-Site Request Forgery (CSRF) attacks, XSS attacks, click-jacking, and MIME based attacks.

Apache CXF Fediz ships with an OpenId Connect (OIDC) service which has a Client Registration Service, which is a simple web application that allows clients to be created, deleted, etc. A CSRF (Cross Style Request Forgery) style vulnerability has been found in this web application in Apache CXF Fediz prior to 1.4.0 and 1.3.2, meaning that a malicious web application could create new clients, or reset secrets, etc, after the admin user has logged on to the client registration service and the session is still active.

Apache CXF Fediz ships with a number of container-specific plugins to enable WS-Federation for applications. A CSRF (Cross Style Request Forgery) style vulnerability has been found in the Spring 2, Spring 3, Jetty 8 and Jetty 9 plugins in Apache CXF Fediz prior to 1.4.0, 1.3.2 and 1.2.4.

Two errors in the "asn1_find_node()" function (lib/parser_aux.c) within GnuTLS libtasn1 version 4.10 can be exploited to cause a stacked-based buffer overflow by tricking a user into processing a specially crafted assignments file via the e.g. asn1Coding utility.

Cross-site scripting (XSS) vulnerability in the default error page of Apache 2.0 before 2.0.43, and 1.3.x up to 1.3.26, when UseCanonicalName is "Off" and support for wildcard DNS is present, allows remote attackers to execute script as other web page visitors via the Host: header, a different vulnerability than CAN-2002-1157.

A race condition in Guacamole's terminal emulator in versions 0.9.5 through 0.9.10-incubating could allow writes of blocks of printed data to overlap. Such overlapping writes could cause packet data to be misread as the packet length, resulting in the remaining data being written beyond the end of a statically-allocated buffer.

In Apache Airflow 1.8.2 and earlier, a CSRF vulnerability allowed for a remote command injection on a default install of Airflow.

Apache Karaf allows monitoring of applications and the Java runtime by using the Java Management Extensions (JMX). JMX is a Java RMI based technology that relies on Java serialized objects for client server communication. Whereas the default JMX implementation is hardened against unauthenticated deserialization attacks, the implementation used by Apache Karaf is not protected against this kind of attack. The impact of Java deserialization vulnerabilities strongly depends on the classes that are available within the targets class path. Generally speaking, deserialization of untrusted data does always represent a high security risk and should be prevented. The risk is low as, by default, Karaf uses a limited set of classes in the JMX server class path. It depends of system scoped classes (e.g. jar in the lib folder).

A crafted request uri-path can cause mod_proxy to forward the request to an origin server choosen by the remote user. This issue affects Apache HTTP Server 2.4.48 and earlier.

A vulnerability in the OpenOffice Writer DOC file parser before 4.1.4, and specifically in the WW8Fonts Constructor, allows attackers to craft malicious documents that cause denial of service (memory corruption and application crash) potentially resulting in arbitrary code execution.

Apache jUDDI uses several classes related to Java's Remote Method Invocation (RMI) which (as an extension to UDDI) provides an alternate transport for accessing UDDI services. RMI uses the default Java serialization mechanism to pass parameters in RMI invocations. A remote attacker can send a malicious serialized object to the above RMI entries. The objects get deserialized without any check on the incoming data. In the worst case, it may let the attacker run arbitrary code remotely. For both jUDDI web service applications and jUDDI clients, the usage of RMI is disabled by default. Since this is an optional feature and an extension to the UDDI protocol, the likelihood of impact is low. Starting with 3.3.10, all RMI related code was removed.

In Apache httpd 2.4.0 to 2.4.29, the expression specified in <FilesMatch> could match '$' to a newline character in a malicious filename, rather than matching only the end of the filename. This could be exploited in environments where uploads of some files are are externally blocked, but only by matching the trailing portion of the filename.

Cross-site scripting (XSS) vulnerability in the forum implementation in the ecommerce component in the Apache Open For Business Project (OFBiz) allows remote attackers to inject arbitrary web script or HTML by posting a message.

Integer underflow in LibreOffice before 4.4.5 and Apache OpenOffice before 4.1.2, when the configuration setting "Load printer settings with the document" is enabled, allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via crafted PrinterSetup data in an ODF document.

The project received a report that all versions of Apache OpenOffice through 4.1.8 can open non-http(s) hyperlinks. The problem has existed since about 2006 and the issue is also in 4.1.9. If the link is specifically crafted this could lead to untrusted code execution. It is always best practice to be careful opening documents from unknown and unverified sources. The mitigation in Apache OpenOffice 4.1.10 (unreleased) assures that a security warning is displayed giving the user the option of continuing to open the hyperlink.

Apache Dubbo prior to 2.7.9 support Tag routing which will enable a customer to route the request to the right server. These rules are used by the customers when making a request in order to find the right endpoint. When parsing these YAML rules, Dubbo customers may enable calling arbitrary constructors.

A deserialization flaw was found in Apache Chainsaw versions prior to 2.1.0 which could lead to malicious code execution.

When running Apache Tomcat 7.0.0 to 7.0.79 on Windows with HTTP PUTs enabled (e.g. via setting the readonly initialisation parameter of the Default 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.

HtmlUnit prior to 2.37.0 contains code execution vulnerabilities. HtmlUnit initializes Rhino engine improperly, hence a malicious JavScript code can execute arbitrary Java code on the application. Moreover, when embedded in Android application, Android-specific initialization of Rhino engine is done in an improper way, hence a malicious JavaScript code can execute arbitrary Java code on the application.

Apache CXF Fediz ships with a number of container-specific plugins to enable WS-Federation for applications. A CSRF (Cross Style Request Forgery) style vulnerability has been found in the Spring 2, Spring 3 and Spring 4 plugins in versions before 1.4.3 and 1.3.3. The vulnerability can result in a security context that is set up using a malicious client's roles for the given enduser.

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.

A vulnerability in OpenOffice's PPT file parser before 4.1.4, and specifically in PPTStyleSheet, allows attackers to craft malicious documents that cause denial of service (memory corruption and application crash) potentially resulting in arbitrary code execution.

An issue was discovered in Legion of the Bouncy Castle BC Java 1.65 and 1.66. The OpenBSDBCrypt.checkPassword utility method compared incorrect data when checking the password, allowing incorrect passwords to indicate they were matching with previously hashed ones that were different.

A vulnerability in Apache OpenOffice Writer DOC file parser before 4.1.4, and specifically in ImportOldFormatStyles, allows attackers to craft malicious documents that cause denial of service (memory corruption and application crash) potentially resulting in arbitrary code execution.

Out-of-bounds Write vulnerability in TCP Stack of Apache NuttX (incubating) versions up to and including 9.1.0 and 10.0.0 allows attacker to corrupt memory by supplying and invalid fragmentation offset value specified in the IP header. This is only impacts builds with both CONFIG_EXPERIMENTAL and CONFIG_NET_TCP_REASSEMBLY build flags enabled.

If Apache TomEE 8.0.0-M1 - 8.0.3, 7.1.0 - 7.1.3, 7.0.0-M1 - 7.0.8, 1.0.0 - 1.7.5 is configured to use the embedded ActiveMQ broker, and the broker config is misconfigured, a JMX port is opened on TCP port 1099, which does not include authentication. CVE-2020-11969 previously addressed the creation of the JMX management interface, however the incomplete fix did not cover this edge case.

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.

Unsafe deserialization occurs within a Dubbo application which has HTTP remoting enabled. An attacker may submit a POST request with a Java object in it to completely compromise a Provider instance of Apache Dubbo, if this instance enables HTTP. This issue affected Apache Dubbo 2.7.0 to 2.7.4, 2.6.0 to 2.6.7, and all 2.5.x versions.

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

Apache Struts 2.0.0 through 2.3.x before 2.3.20 uses predictable <s:token/> values, which allows remote attackers to bypass the CSRF protection mechanism.

CVE-2018-8025 describes an issue in Apache HBase that affects the optional "Thrift 1" API server when running over HTTP. There is a race-condition which could lead to authenticated sessions being incorrectly applied to users, e.g. one authenticated user would be considered a different user or an unauthenticated user would be treated as an authenticated user. https://issues.apache.org/jira/browse/HBASE-20664 implements a fix for this issue. It has been fixed in versions: 1.2.6.1, 1.3.2.1, 1.4.5, 2.0.1.

When running on Windows with enableCmdLineArguments enabled, the CGI Servlet in Apache Tomcat 9.0.0.M1 to 9.0.17, 8.5.0 to 8.5.39 and 7.0.0 to 7.0.93 is vulnerable to Remote Code Execution due to a bug in the way the JRE passes command line arguments to Windows. The CGI Servlet is disabled by default. The CGI option enableCmdLineArguments is disable by default in Tomcat 9.0.x (and will be disabled by default in all versions in response to this vulnerability). For a detailed explanation of the JRE behaviour, see Markus Wulftange's blog (https://codewhitesec.blogspot.com/2016/02/java-and-command-line-injections-in-windows.html) and this archived MSDN blog (https://web.archive.org/web/20161228144344/https://blogs.msdn.microsoft.com/twistylittlepassagesallalike/2011/04/23/everyone-quotes-command-line-arguments-the-wrong-way/).

A carefully crafted or corrupt zip file can cause an OOM in Apache Tika's RecursiveParserWrapper in versions 1.7-1.21. Users should upgrade to 1.22 or later.

Apache OFBiz 17.12.01 is vulnerable to some CSRF attacks.

A number of HTTP endpoints in the Airflow webserver (both RBAC and classic) did not have adequate protection and were vulnerable to cross-site request forgery attacks.
