Apache Software Foundation CouchDB any version

Due to differences in the Erlang-based JSON parser and JavaScript-based JSON parser, it is possible in Apache CouchDB before 1.7.0 and 2.x before 2.1.1 to submit _users documents with duplicate keys for 'roles' used for access control within the database, including the special case '_admin' role, that denotes administrative users. In combination with CVE-2017-12636 (Remote Code Execution), this can be used to give non-admin users access to arbitrary shell commands on the server as the database system user. The JSON parser differences result in behaviour that if two 'roles' keys are available in the JSON, the second one will be used for authorising the document write, but the first 'roles' key is used for subsequent authorization for the newly created user. By design, users can not assign themselves roles. The vulnerability allows non-admin users to give themselves admin privileges.

Remote Code Execution Vulnerability in Packaging

CouchDB administrative users can configure the database server via HTTP(S). Some of the configuration options include paths for operating system-level binaries that are subsequently launched by CouchDB. This allows an admin user in Apache CouchDB before 1.7.0 and 2.x before 2.1.1 to execute arbitrary shell commands as the CouchDB user, including downloading and executing scripts from the public internet.

Apache CouchDB administrative users can configure the database server via HTTP(S). Due to insufficient validation of administrator-supplied configuration settings via the HTTP API, it is possible for a CouchDB administrator user to escalate their privileges to that of the operating system's user that CouchDB runs under, by bypassing the blacklist of configuration settings that are not allowed to be modified via the HTTP API. This privilege escalation effectively allows an existing CouchDB admin user to gain arbitrary remote code execution, bypassing already disclosed CVE-2017-12636. Mitigation: All users should upgrade to CouchDB releases 1.7.2 or 2.1.2.

CouchDB administrative users before 2.2.0 can configure the database server via HTTP(S). Due to insufficient validation of administrator-supplied configuration settings via the HTTP API, it is possible for a CouchDB administrator user to escalate their privileges to that of the operating system's user under which CouchDB runs, by bypassing the blacklist of configuration settings that are not allowed to be modified via the HTTP API. This privilege escalation effectively allows a CouchDB admin user to gain arbitrary remote code execution, bypassing CVE-2017-12636 and CVE-2018-8007.

CouchDB in Vectra Networks Cognito Brain and Sensor before 4.3 contains a local code execution vulnerability.

Privilege escalation vulnerability when using HTML attachments

Prior to CouchDB version 2.3.0, CouchDB allowed for runtime-configuration of key components of the database. In some cases, this lead to vulnerabilities where CouchDB admin users could access the underlying operating system as the CouchDB user. Together with other vulnerabilities, it allowed full system entry for unauthenticated users. Rather than waiting for new vulnerabilities to be discovered, and fixing them as they come up, the CouchDB development team decided to make changes to avoid this entire class of vulnerabilities.

Apache CouchDB before 1.0.4, 1.1.x before 1.1.2, and 1.2.x before 1.2.1 allows remote attackers to execute arbitrary code via a JSONP callback, related to Adobe Flash.

Apache CouchDB 1.5.0 and earlier allows remote attackers to cause a denial of service (CPU and memory consumption) via the count parameter to /_uuids.

Directory traversal vulnerability in the partition2 function in mochiweb_util.erl in MochiWeb before 2.4.0, as used in Apache CouchDB before 1.0.4, 1.1.x before 1.1.2, and 1.2.x before 1.2.1, allows remote attackers to read arbitrary files via a ..\ (dot dot backslash) in the default URI.

Cross-site scripting (XSS) vulnerability in the Futon UI in Apache CouchDB before 1.0.4, 1.1.x before 1.1.2, and 1.2.x before 1.2.1 allows remote attackers to inject arbitrary web script or HTML via unspecified parameters to the browser-based test suite.
