MySQL version 5.5.23 releases notes mention following security fix:

Security Fix: Bug #59533 was fixed.

http://dev.mysql.com/doc/refman/5.5/en/news-5-5-23.html

Upstream bug is currently private and there's no additional info currently available for this issue. The bug is not referenced by any commit in the upstream bazaar repositories.

Oracle MySQL through 5.5.52, 5.6.x through 5.6.33, and 5.7.x through 5.7.15; MariaDB before 5.5.51, 10.0.x before 10.0.27, and 10.1.x before 10.1.17; and Percona Server before 5.5.51-38.1, 5.6.x before 5.6.32-78.0, and 5.7.x before 5.7.14-7 allow local users to create arbitrary configurations and bypass certain protection mechanisms by setting generallogfile to a my.cnf configuration. NOTE: this can be leveraged to execute arbitrary code with root privileges by setting malloclib. NOTE: the affected MySQL version information is from Oracle's October 2016 CPU. Oracle has not commented on third-party claims that the issue was silently patched in MySQL 5.5.52, 5.6.33, and 5.7.15.

MariaDB server is a community developed fork of MySQL server. An authenticated user can crash MariaDB versions 11.4 before 11.4.10 and 11.8 before 11.8.6 via a bug in JSONSCHEMAVALID() function. Under certain conditions it might be possible to turn the crash into a remote code execution. These conditions require tight control over memory layout which is generally only attainable in a lab environment. This issue is fixed in MariaDB 11.4.10, MariaDB 11.8.6, and MariaDB 12.2.2.

MariaDB v10.5 was discovered to contain a remote code execution (RCE) vulnerability via UDF Code in a Shared Object File, followed by a "create function" statement. NOTE: this is disputed by the MariaDB Foundation because no privilege boundary is crossed.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of MySQL. Authentication is not required to exploit this vulnerability. The specific flaw exists within the processing of Append and Prepend commands in the memcached plugin. The issue results from the lack of proper validation of user-supplied data, which can result in an integer underflow before writing to memory. An attacker can leverage this vulnerability to execute code in the context of the service account.

Unspecified vulnerability in the MySQL Server component in Oracle MySQL 5.1.64 and earlier, and 5.5.26 and earlier, allows remote authenticated users to affect confidentiality, integrity, and availability via unknown vectors related to Information Schema.

A flaw was found in the mysql-wsrep component of mariadb. Lack of input sanitization in wsrepsstmethod allows for command injection that can be exploited by a remote attacker to execute arbitrary commands on galera cluster nodes. This threatens the system's confidentiality, integrity, and availability. This flaw affects mariadb versions before 10.1.47, before 10.2.34, before 10.3.25, before 10.4.15 and before 10.5.6.

A remote code execution issue was discovered in MariaDB 10.2 before 10.2.37, 10.3 before 10.3.28, 10.4 before 10.4.18, and 10.5 before 10.5.9; Percona Server through 2021-03-03; and the wsrep patch through 2021-03-03 for MySQL. An untrusted search path leads to eval injection, in which a database SUPER user can execute OS commands after modifying wsrepprovider and wsrepnotifycmd. NOTE: this does not affect an Oracle product.

MariaDB have noted in their release notes that reserved CVE-2017-15365 has been fixed in version 10.2.10[1], however they have not described how or what the vulnerability was. This CVE is also mentioned to affect Percona[2] with the fix is described as:

"Added access checks for DDL commands to make sure they do not get replicated if they failed without proper permissions"

A comparison with the MariaDB 10.2.10 changelog[3] and Percona description finds this commit[4], which seems a likely candidate for both describing and fixing the vulnerability. The vulnerable code block in sql/eventdataobjects.cc is also present in version 10.1, suggesting that it is also affected.

Unspecified vulnerability in Oracle MySQL 5.5.49 and earlier, 5.6.30 and earlier, and 5.7.12 and earlier and MariaDB before 5.5.50, 10.0.x before 10.0.26, and 10.1.x before 10.1.15 allows local users to affect confidentiality, integrity, and availability via vectors related to Server: Parser.

The installation scripts in the Gentoo dev-db/mysql, dev-db/mariadb, dev-db/percona-server, dev-db/mysql-cluster, and dev-db/mariadb-galera packages before 2017-09-29 have chown calls for user-writable directory trees, which allows local users to gain privileges by leveraging access to the mysql account for creation of a link.

The compilebranch function in PCRE before 8.37 allows context-dependent attackers to compile incorrect code, cause a denial of service (out-of-bounds heap read and crash), or possibly have other unspecified impact via a regular expression with a group containing a forward reference repeated a large number of times within a repeated outer group that has a zero minimum quantifier.

MariaDB CONNECT Storage Engine Stack-based Buffer Overflow Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of MariaDB. Authentication is required to exploit this vulnerability. The specific flaw exists within the processing of SQL queries. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the service account.

MariaDB CONNECT Storage Engine Use-After-Free Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of MariaDB. Authentication is required to exploit this vulnerability. The specific flaw exists within the processing of SQL queries. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the service account. Was ZDI-CAN-16207.

MariaDB CONNECT Storage Engine Format String Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of MariaDB. Authentication is required to exploit this vulnerability. The specific flaw exists within the processing of SQL queries. The issue results from the lack of proper validation of a user-supplied string before using it as a format specifier. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the service account.

mysqlinstalldb in MariaDB 10.4.7 through 10.4.11 allows privilege escalation from the mysql user account to root because chown and chmod are performed unsafely, as demonstrated by a symlink attack on a chmod 04755 of authpamtooldir/authpamtool. NOTE: this does not affect the Oracle MySQL product, which implements mysqlinstalldb differently.

Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: Optimizer). Supported versions that are affected are 5.5.54 and earlier, 5.6.35 and earlier and 5.7.17 and earlier. Easily "exploitable" vulnerability allows low privileged attacker with network access via multiple protocols to compromise MySQL Server. While the vulnerability is in MySQL Server, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server. CVSS 3.0 Base Score 7.7 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H).

Withdrawn Advisory

This advisory has been withdrawn because MariaDB now owns https://www.npmjs.com/package/mariadb and the package is no longer malicious. This link is maintained to preserve external references.

Original Description

The mariadb package is a piece of malware that steals environment variables and sends them to attacker controlled locations.

All versions have been unpublished from the npm registry.

Recommendation

As this package is malware, if you find it installed in your environment, the real security concern is determining how it got there.

If you have found this installed in your environment, you should: 1. Delete the package 2. Clear your npm cache 3. Ensure it is not present in any other package.json files on your system 4. Regenerate your registry credentials, tokens, and any other sensitive credentials that may have been present in your environment variables.

Additionally, any service which may have been exposed via credentials in your environment variables, such as a database, should be reviewed for indicators of compromise as well.
