An unprivileged user or program on Microsoft Windows which can create OpenSSL configuration files in a fixed location may cause utility programs shipped with MongoDB server to run attacker defined code as the user running the utility. This issue MongoDB Server v4.0 versions prior to 4.0.11; MongoDB Server v3.6 versions prior to 3.6.14 and MongoDB Server v3.4 prior to 3.4.22.

Incorrect scoping of kill operations in MongoDB Server's packaged SysV init scripts allow users with write access to the PID file to insert arbitrary PIDs to be killed when the root user stops the MongoDB process via SysV init. This issue affects MongoDB Server v4.0 versions prior to 4.0.11; MongoDB Server v3.6 versions prior to 3.6.14; MongoDB Server v3.4 versions prior to 3.4.22.

After user deletion in MongoDB Server the improper invalidation of authorization sessions allows an authenticated user's session to persist and become conflated with new accounts, if those accounts reuse the names of deleted ones. This issue affects MongoDB Server v4.0 versions prior to 4.0.9; MongoDB Server v3.6 versions prior to 3.6.13 and MongoDB Server v3.4 versions prior to 3.4.22. Workaround: After deleting one or more users, restart any nodes which may have had active user authorization sessions. Refrain from creating user accounts with the same name as previously deleted accounts.

The installation process in Open edX before 2017-01-10 exposes a MongoDB instance to external connections with default credentials.

Improper handling of LDAP authentication in MongoDB Server versions 3.0.0 to 3.0.6 allows an unauthenticated client to gain unauthorized access.

When using IBM Spectrum Protect Plus 10.1.0, 10.1.2, and 10.1.3 to protect Oracle or MongoDB databases, a redirected restore operation may result in an escalation of user privileges. IBM X-Force ID: 162165.

When using IBM Spectrum Protect Plus 10.1.0, 10.1.2, and 10.1.3 to protect Oracle, DB2 or MongoDB databases, a redirected restore operation specifying a target path may allow execution of arbitrary code on the system. IBM X-Force ID: 161667,

IBM API Connect 5.0.0.0 and 5.0.8.4 is affected by a NoSQL Injection in MongoDB connector for the LoopBack framework. IBM X-Force ID: 148807.

_bson_iter_next_internal in bson-iter.c in libbson 1.12.0, as used in MongoDB mongo-c-driver and other products, has a heap-based buffer over-read via a crafted bson buffer.

A privilege escalation detected in flintcms versions <= 1.1.9 allows account takeover due to blind MongoDB injection in password reset.

The MongoDB bson JavaScript module (also known as js-bson) versions 0.5.0 to 1.0.x before 1.0.5 is vulnerable to a Regular Expression Denial of Service (ReDoS) in lib/bson/decimal128.js. The flaw is triggered when the Decimal128.fromString() function is called to parse a long untrusted string.

The skyring-setup command creates random password for mongodb skyring database but it writes password in plain text to /etc/skyring/skyring.conf file which is owned by root but read by local user. Any local user who has access to system running skyring service will be able to get password in plain text.

mongodb-instance before 0.0.3 installs mongodb locally. mongodb-instance downloads binary resources over HTTP, which leaves it vulnerable to MITM attacks. It may be possible to cause remote code execution (RCE) by swapping out the requested binary with an attacker controlled binary if the attacker is on the network or positioned in between the user and the remote server.

Etherpad 1.5.x and 1.6.x before 1.6.4 allows an attacker to execute arbitrary code on the server. The instance has to be configured to use a document database (DirtyDB, CouchDB, MongoDB, or RethinkDB).

MongoDB 3.4.x before 3.4.10, and 3.5.x-development, has a disabled-by-default configuration setting, networkMessageCompressors (aka wire protocol compression), which exposes a vulnerability when enabled that could be exploited by a malicious attacker to deny service or modify memory.

In MongoDB libbson 1.7.0, the bson_iter_codewscope function in bson-iter.c miscalculates a bson_utf8_validate length argument, which allows remote attackers to cause a denial of service (heap-based buffer over-read in the bson_utf8_validate function in bson-utf8.c), as demonstrated by bson-to-json.c.

MongoDB on Red Hat Satellite 6 allows local users to bypass authentication by logging in with an empty password and delete information which can cause a Denial of Service.

mongod in MongoDB 2.6, when using 2.4-style users, and 2.4 allow remote attackers to cause a denial of service (memory consumption and process termination) by leveraging in-memory database representation when authenticating against a non-existent database.

The client in MongoDB uses world-readable permissions on .dbshell history files, which might allow local users to obtain sensitive information by reading these files.

Doctrine Annotations before 1.2.7, Cache before 1.3.2 and 1.4.x before 1.4.2, Common before 2.4.3 and 2.5.x before 2.5.1, ORM before 2.4.8 or 2.5.x before 2.5.1, MongoDB ODM before 1.0.2, and MongoDB ODM Bundle before 3.0.1 use world-writable permissions for cache directories, which allows local users to execute arbitrary PHP code with additional privileges by leveraging an application with the umask set to 0 and that executes cache entries as code.
