Apache Hadoop 0.23.x before 0.23.11 and 2.x before 2.4.1, as used in Cloudera CDH 5.0.x before 5.0.2, do not check authorization for the (1) refreshNamenodes, (2) deleteBlockPool, and (3) shutdownDatanode HDFS admin commands, which allows remote authenticated users to cause a denial of service (DataNodes shutdown) or perform unnecessary operations by issuing a command.

In Apache Brooklyn before 0.10.0, the REST server is vulnerable to cross-site scripting where one authenticated user can cause scripts to run in the browser of another user authorized to access the first user's resources. This is due to improper escaping of server-side content. There is known to be a proof-of-concept exploit using this vulnerability.

subversion: Command injection through clients via malicious svn+ssh URLs

A maliciously constructed svn+ssh:// URL would cause Subversion clients before 1.8.19, 1.9.x before 1.9.7, and 1.10.0.x through 1.10.0-alpha3 to run an arbitrary shell command. Such a URL could be generated by a malicious server, by a malicious user committing to a honest server (to attack another user of that server's repositories), or by a proxy server. The vulnerability affects all clients, including those that use file://, http://, and plain (untunneled) svn://.

It was found that under some situations and configurations of Apache Storm 1.x before 1.0.4 and 1.1.x before 1.1.1, it is theoretically possible for the owner of a topology to trick the supervisor to launch a worker as a different, non-root, user. In the worst case this could lead to secure credentials of the other user being compromised.

In Apache Hadoop versions 2.6.1 to 2.6.5, 2.7.0 to 2.7.3, and 3.0.0-alpha1, if a file in an encryption zone with access permissions that make it world readable is localized via YARN's localization mechanism, that file will be stored in a world-readable location and can be shared freely with any application that requests to localize that file.

When an Apache Geode cluster before v1.2.1 is operating in secure mode, an unauthenticated client can enter multi-user authentication mode and send metadata messages. These metadata operations could leak information about application data types. In addition, an attacker could perform a denial of service attack on the cluster.

apache-cxf: XSS in Apache CXF FormattedServiceListWriter

The HTTP transport module in Apache CXF prior to 3.0.12 and 3.1.x prior to 3.1.9 uses FormattedServiceListWriter to provide an HTML page which lists the names and absolute URL addresses of the available service endpoints. The module calculates the base URL using the current HttpServletRequest. The calculated base URL is used by FormattedServiceListWriter to build the service endpoint absolute URLs. If the unexpected matrix parameters have been injected into the request URL then these matrix parameters will find their way back to the client in the services list page which represents an XSS risk to the client.

When a cluster is operating in secure mode, a user with read privileges for specific data regions can use the gfsh command line utility to execute queries. In Apache Geode before 1.2.1, the query results may contain data from another user's concurrently executing gfsh query, potentially revealing data that the user is not authorized to view.

struts: DoS attack via crafted XML payload processed by REST Plugin using XStream library

The REST Plugin in Apache Struts 2.1.x, 2.3.7 through 2.3.33 and 2.5 through 2.5.12 is using an outdated XStream library which is vulnerable and allow perform a DoS attack using malicious request with specially crafted XML payload.

The UI daemon in Apache Storm 0.10.0 before 0.10.0-beta1 allows remote attackers to execute arbitrary code via unspecified vectors.

In Apache Impala (incubating) before 2.10.0, a malicious user with "ALTER" permissions on an Impala table can access any other Kudu table data by altering the table properties to make it "external" and then changing the underlying table mapping to point to other Kudu tables. This violates and works around the authorization requirement that creating a Kudu external table via Impala requires an "ALL" privilege at the server scope. This privilege requirement for "CREATE" commands is enforced to precisely avoid this scenario where a malicious user can change the underlying Kudu table mapping. The fix is to enforce the same privilege requirement for "ALTER" commands that would make existing non-external Kudu tables external.

When handling a libprocess message wrapped in an HTTP request, libprocess in Apache Mesos before 1.1.3, 1.2.x before 1.2.2, 1.3.x before 1.3.1, and 1.4.0-dev crashes if the request path is empty, because the parser assumes the request path always starts with '/'. A malicious actor can therefore cause a denial of service of Mesos masters rendering the Mesos-controlled cluster inoperable.

httpd: Read after free in mod_http2

When under stress, closing many connections, the HTTP/2 handling code in Apache httpd 2.4.26 would sometimes access memory after it has been freed, resulting in potentially erratic behaviour.

httpd: Uninitialized memory reflection in mod_auth_digest

In Apache httpd before 2.2.34 and 2.4.x before 2.4.27, the value placeholder in [Proxy-]Authorization headers of type 'Digest' was not initialized or reset before or between successive key=value assignments by mod_auth_digest. Providing an initial key with no '=' assignment could reflect the stale value of uninitialized pool memory used by the prior request, leading to leakage of potentially confidential information, and a segfault in other cases resulting in denial of service.

struts: Denial of service when using a Spring AOP functionality

When using a Spring AOP functionality to secure Struts actions it is possible to perform a DoS attack. Solution is to upgrade to Apache Struts version 2.5.12 or 2.3.33.

When handling a decoding failure for a malformed URL path of an HTTP request, libprocess in Apache Mesos before 1.1.3, 1.2.x before 1.2.2, 1.3.x before 1.3.1, and 1.4.0-dev might crash because the code accidentally calls inappropriate function. A malicious actor can therefore cause a denial of service of Mesos masters rendering the Mesos-controlled cluster inoperable.

Apache Ignite 1.0.0-RC3 to 2.0 uses an update notifier component to update the users about new project releases that include additional functionality, bug fixes and performance improvements. To do that the component communicates to an external PHP server (http://ignite.run) where it needs to send some system properties like Apache Ignite or Java version. Some of the properties might contain user sensitive information.

Apache OpenMeetings 1.0.0 responds to the following insecure HTTP methods: PUT, DELETE, HEAD, and PATCH.

Apache OpenMeetings 1.0.0 doesn't check contents of files being uploaded. An attacker can cause a denial of service by uploading multiple large files to the server.

netty: Infinite loop vulnerability when handling renegotiation using SslProvider.OpenSsl

handler/ssl/OpenSslEngine.java in Netty 4.0.x before 4.0.37.Final and 4.1.x before 4.1.1.Final allows remote attackers to cause a denial of service (infinite loop).
