SQLLoginModule in Apache Geronimo 2.0 through 2.1 does not throw an exception for a nonexistent username, which allows remote attackers to bypass authentication via a login attempt with any username not contained in the database.

The authorization framework in Apache Hive 1.0.0, 1.0.1, 1.1.0, 1.1.1, 1.2.0 and 1.2.1, on clusters protected by Ranger and SqlStdHiveAuthorization, allows attackers to bypass intended parent table access restrictions via unspecified partition-level operations.

Apache Pony Mail 0.6c through 0.8b allows remote attackers to bypass authentication.

The LDAPLoginModule implementation in the Java Authentication and Authorization Service (JAAS) in Apache ActiveMQ 5.x before 5.10.1 allows remote attackers to bypass authentication by logging in with an empty password and valid username, which triggers an unauthenticated bind. NOTE: this identifier has been SPLIT per ADT2 due to different vulnerability types. See CVE-2015-6524 for the use of wildcard operators in usernames.

The Admin UI in Apache Ranger before 0.5.1 does not properly handle authentication requests that lack a password, which allows remote attackers to bypass authentication by leveraging knowledge of a valid username.

It was noticed that a malicious process impersonating an Impala daemon in Apache Impala (incubating) 2.7.0 to 2.8.0 could cause Impala daemons to skip authentication checks when Kerberos is enabled (but TLS is not). If the malicious server responds with 'COMPLETE' before the SASL handshake has completed, the client will consider the handshake as completed even though no exchange of credentials has happened.

The WS-SP UsernameToken policy in Apache CXF 2.4.5 and 2.5.1 allows remote attackers to bypass authentication by sending an empty UsernameToken as part of a SOAP request.

Apache Shiro before 1.7.0, when using Apache Shiro with Spring, a specially crafted HTTP request may cause an authentication bypass.

Apache Qpid 0.12 does not properly verify credentials during the joining of a cluster, which allows remote attackers to obtain access to the messaging functionality and job functionality of a cluster by leveraging knowledge of a cluster-username.

Apache Shiro before 1.8.0, when using Apache Shiro with Spring Boot, a specially crafted HTTP request may cause an authentication bypass. Users should update to Apache Shiro 1.8.0.

In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, use of the ap_get_basic_auth_pw() by third-party modules outside of the authentication phase may lead to authentication requirements being bypassed.

CoreResponseStateManager in Apache MyFaces Trinidad 1.0.0 through 1.0.13, 1.2.x before 1.2.15, 2.0.x before 2.0.2, and 2.1.x before 2.1.2 might allow attackers to conduct deserialization attacks via a crafted serialized view state string.

Jodd before 5.0.4 performs Deserialization of Untrusted JSON Data when setClassMetadataName is set.

The fix issued for CVE-2020-17530 was incomplete. So from Apache Struts 2.0.0 to 2.5.29, still some of the tag’s attributes could perform a double evaluation if a developer applied forced OGNL evaluation by using the %{...} syntax. Using forced OGNL evaluation on untrusted user input can lead to a Remote Code Execution and security degradation.

In Apache Synapse, by default no authentication is required for Java Remote Method Invocation (RMI). So Apache Synapse 3.0.1 or all previous releases (3.0.0, 2.1.0, 2.0.0, 1.2, 1.1.2, 1.1.1) allows remote code execution attacks that can be performed by injecting specially crafted serialized objects. And the presence of Apache Commons Collections 3.2.1 (commons-collections-3.2.1.jar) or previous versions in Synapse distribution makes this exploitable. To mitigate the issue, we need to limit RMI access to trusted users only. Further upgrading to 3.0.1 version will eliminate the risk of having said Commons Collection version. In Synapse 3.0.1, Commons Collection has been updated to 3.2.2 version.

The (1) UpdateRequestHandler for XSLT or (2) XPathEntityProcessor in Apache Solr before 4.1 allows remote attackers to have an unspecified impact via XML data containing an external entity declaration in conjunction with an entity reference, related to an XML External Entity (XXE) issue, different vectors than CVE-2013-6407.

The application plugins in Apache CXF Fediz 1.2.x before 1.2.3 and 1.3.x before 1.3.1 do not match SAML AudienceRestriction values against configured audience URIs, which might allow remote attackers to have bypass intended restrictions and have unspecified other impact via a crafted SAML token with a trusted signature.

SQL injection vulnerability in mod_auth_mysql.c in the mod-auth-mysql (aka libapache2-mod-auth-mysql) module for the Apache HTTP Server 2.x, when configured to use a multibyte character set that allows a \ (backslash) as part of the character encoding, allows remote attackers to execute arbitrary SQL commands via unspecified inputs in a login request.

Remote code execution occurs in Apache Solr before 7.1 with Apache Lucene before 7.1 by exploiting XXE in conjunction with use of a Config API add-listener command to reach the RunExecutableListener class. Elasticsearch, although it uses Lucene, is NOT vulnerable to this. Note that the XML external entity expansion vulnerability occurs in the XML Query Parser which is available, by default, for any query request with parameters deftype=xmlparser and can be exploited to upload malicious data to the /upload request handler or as Blind XXE using ftp wrapper in order to read arbitrary local files from the Solr server. Note also that the second vulnerability relates to remote code execution using the RunExecutableListener available on all affected versions of Solr.

Apache Struts 2.3.19 to 2.3.20.2, 2.3.21 to 2.3.24.1, and 2.3.25 to 2.3.28, when Dynamic Method Invocation is enabled, allow remote attackers to execute arbitrary code via vectors related to an ! (exclamation mark) operator to the REST Plugin.

DataNodes in Apache Hadoop 2.0.0 alpha does not check the BlockTokens of clients when Kerberos is enabled and the DataNode has checked out the same BlockPool twice from a NodeName, which might allow remote clients to read arbitrary blocks, write to blocks to which they only have read access, and have other unspecified impacts.

Apache Commons FileUpload before 1.3.3 DiskFileItem File Manipulation Remote Code Execution

When loading models or dictionaries that contain XML it is possible to perform an XXE attack, since Apache OpenNLP is a library, this only affects applications that load models or dictionaries from untrusted sources.

Apache HBase 0.98 before 0.98.12.1, 1.0 before 1.0.1.1, and 1.1 before 1.1.0.1, as used in IBM InfoSphere BigInsights 3.0, 3.0.0.1, and 3.0.0.2 and other products, uses incorrect ACLs for ZooKeeper coordination state, which allows remote attackers to cause a denial of service (daemon outage), obtain sensitive information, or modify data via unspecified client traffic.

Remote code execution is possible with Apache Tomcat before 6.0.48, 7.x before 7.0.73, 8.x before 8.0.39, 8.5.x before 8.5.7, and 9.x before 9.0.0.M12 if JmxRemoteLifecycleListener is used and an attacker can reach JMX ports. The issue exists because this listener wasn't updated for consistency with the CVE-2016-3427 Oracle patch that affected credential types.

Apache Camel's Jackson and JacksonXML unmarshalling operation are vulnerable to Remote Code Execution attacks.

Stack-based buffer overflow in the map_uri_to_worker function (native/common/jk_uri_worker_map.c) in mod_jk.so for Apache Tomcat JK Web Server Connector 1.2.19 and 1.2.20, as used in Tomcat 4.1.34 and 5.5.20, allows remote attackers to execute arbitrary code via a long URL that triggers the overflow in a URI worker map routine.

The forum implementation in the ecommerce component in the Apache Open For Business Project (OFBiz) trusts the (1) dataResourceTypeId, (2) contentTypeId, and certain other hidden form fields, which allows remote attackers to create unauthorized types of content, modify content, or have other unknown impact.

Apache Standard Taglibs before 1.2.3 allows remote attackers to execute arbitrary code or conduct external XML entity (XXE) attacks via a crafted XSLT extension in a (1) <x:parse> or (2) <x:transform> JSTL XML tag.

The Apache XML-RPC (aka ws-xmlrpc) library 3.1.3, as used in Apache Archiva, allows remote attackers to execute arbitrary code via a crafted serialized Java object in an <ex:serializable> element.

Apache Commons Configuration performs variable interpolation, allowing properties to be dynamically evaluated and expanded. The standard format for interpolation is "${prefix:name}", where "prefix" is used to locate an instance of org.apache.commons.configuration2.interpol.Lookup that performs the interpolation. Starting with version 2.4 and continuing through 2.7, the set of default Lookup instances included interpolators that could result in arbitrary code execution or contact with remote servers. These lookups are: - "script" - execute expressions using the JVM script execution engine (javax.script) - "dns" - resolve dns records - "url" - load values from urls, including from remote servers Applications using the interpolation defaults in the affected versions may be vulnerable to remote code execution or unintentional contact with remote servers if untrusted configuration values are used. Users are recommended to upgrade to Apache Commons Configuration 2.8.0, which disables the problematic interpolators by default.

The REST plugin in Apache Struts 2 2.3.19 through 2.3.28.1 allows remote attackers to execute arbitrary code via a crafted expression.

The ReplicationHandler (normally registered at "/replication" under a Solr core) in Apache Solr has a "masterUrl" (also "leaderUrl" alias) parameter that is used to designate another ReplicationHandler on another Solr core to replicate index data into the local core. To prevent a SSRF vulnerability, Solr ought to check these parameters against a similar configuration it uses for the "shards" parameter. Prior to this bug getting fixed, it did not. This problem affects essentially all Solr versions prior to it getting fixed in 8.8.2.

Apache OFBiz 12.04.x before 12.04.06 and 13.07.x before 13.07.03 allow remote attackers to execute arbitrary commands via a crafted serialized Java object, related to the Apache Commons Collections library.

Apache Software Foundation (ASF) Struts before 1.2.9 allows remote attackers to bypass validation via a request with a 'org.apache.struts.taglib.html.Constants.CANCEL' parameter, which causes the action to be canceled but would not be detected from applications that do not use the isCancelled check.

Apache httpd cookie buffer overflow for versions 1.1.1 and earlier.
