Similar to CVE-2020-1956, Kylin has one more restful API which concatenates the API inputs into OS commands and then executes them on the server; while the reported API misses necessary input validation, which causes the hackers to have the possibility to execute OS command remotely. Users of all previous versions after 2.3 should upgrade to 3.1.0.
Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in Apache Kylin. A backend API refreshing table catalog may cause the injection to the generated SQL.
This issue affects Apache Kylin: from 4 through 5.0.3.
Users are recommended to upgrade to version 5.0.4, which fixes the issue.
Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability in Apache Kylin. A backend API may bring job config parameters to OS command line.
This issue affects Apache Kylin: from 4 through 5.0.3.
Users are recommended to upgrade to version 5.0.4, which fixes the issue.
Kylin can receive user input and load any class through Class.forName(...). This issue affects Apache Kylin 2 version 2.6.6 and prior versions; Apache Kylin 3 version 3.1.2 and prior versions; Apache Kylin 4 version 4.0.0 and prior versions.
Apache kylin checks the legitimacy of the project before executing some commands with the project name passed in by the user. There is a mismatch between what is being checked and what is being used as the shell command argument in DiagnosisService. This may cause an illegal project name to pass the check and perform the following steps, resulting in a command injection vulnerability. This issue affects Apache Kylin 4.0.0.
Kylin concatenates and executes a Hive SQL in Hive CLI or beeline when building a new segment; some part of the HQL is from system configurations, while the configuration can be overwritten by certain rest api, which makes SQL injection attack is possible. Users of all previous versions after 2.0 should upgrade to 3.1.0.
Kylin's cube designer function has a command injection vulnerability when overwriting system parameters in the configuration overwrites menu. RCE can be implemented by closing the single quotation marks around the parameter value of “-- conf=” to inject any operating system command into the command line parameters. This vulnerability affects Kylin 2 version 2.6.5 and earlier, Kylin 3 version 3.1.2 and earlier, and Kylin 4 version 4.0.1 and earlier.
Diagnosis Controller miss parameter validation, so user may attacked by command injection via HTTP Request.
Apache Kylin 2.3.0, and releases up to 2.6.5 and 3.0.1 has some restful apis which will concatenate os command with the user input string, a user is likely to be able to execute any os command without any protection or validation.
Kylin has some restful apis which will concatenate SQLs with the user input string, a user is likely to be able to run malicious database queries.
In the fix for CVE-2022-24697, a blacklist is used to filter user input commands. But there is a risk of being bypassed. The user can control the command by controlling the kylin.engine.spark-cmd parameter of conf.
In Apache Kylin version 2.0.0 to 4.0.3, there is a Server Config web interface that displays the content of file 'kylin.properties', that may contain serverside credentials. When the kylin service runs over HTTP (or other plain text protocol), it is possible for network sniffers to hijack the HTTP payload and get access to the content of kylin.properties and potentially the containing credentials.
To avoid this threat, users are recommended to
Always turn on HTTPS so that network payload is encrypted.
Avoid putting credentials in kylin.properties, or at least not in plain text. Use network firewalls to protect the serverside such that it is not accessible to external attackers.
Upgrade to version Apache Kylin 4.0.4, which filters out the sensitive content that goes to the Server Config web interface.
Authentication Bypass Using an Alternate Path or Channel vulnerability in Apache Kylin.
This issue affects Apache Kylin: from 4.0.0 through 5.0.2.
Users are recommended to upgrade to version 5.0.3, which fixes the issue.
In Apache Kylin, Cross-origin requests with credentials are allowed to be sent from any origin. This issue affects Apache Kylin 2 version 2.6.6 and prior versions; Apache Kylin 3 version 3.1.2 and prior versions; Apache Kylin 4 version 4.0.0 and prior versions.
All request mappings in StreamingCoordinatorController.java handling /kylin/api/streamingcoordinator/ REST API endpoints did not include any security checks, which allowed an unauthenticated user to issue arbitrary requests, such as assigning/unassigning of streaming cubes, creation/modification and deletion of replica sets, to the Kylin Coordinator. For endpoints accepting node details in HTTP message body, unauthenticated (but limited) server-side request forgery (SSRF) can be achieved. This issue affects Apache Kylin Apache Kylin 3 versions prior to 3.1.2.
Apache Kylin provides encryption classes PasswordPlaceholderConfigurer to help users encrypt their passwords. In the encryption algorithm used by this encryption class, the cipher is initialized with a hardcoded key and IV. If users use class PasswordPlaceholderConfigurer to encrypt their password and configure it into kylin's configuration file, there is a risk that the password may be decrypted. This issue affects Apache Kylin 2 version 2.6.6 and prior versions; Apache Kylin 3 version 3.1.2 and prior versions; Apache Kylin 4 version 4.0.0 and prior versions.
Improper Control of Generation of Code ('Code Injection') vulnerability in Apache Kylin. If an attacker gets access to Kylin's system or project admin permission, the JDBC connection configuration maybe altered to execute arbitrary code from the remote. You are fine as long as the Kylin's system and project admin access is well protected.
This issue affects Apache Kylin: from 4.0.0 through 5.0.1.
Users are recommended to upgrade to version 5.0.2 or above, which fixes the issue.
Server-Side Request Forgery (SSRF) vulnerability in Apache Kylin. Through a kylin server, an attacker may forge a request to invoke "/kylin/api/xxx/diag" api on another internal host and possibly get leaked information. There are two preconditions: 1) The attacker has got admin access to a kylin server; 2) Another internal host has the "/kylin/api/xxx/diag" api
endpoint open for service.
This issue affects Apache Kylin: from 5.0.0 through
5.0.1.
Users are recommended to upgrade to version 5.0.2, which fixes the issue.
Apache Kylin allows users to read data from other database systems using JDBC. The MySQL JDBC driver supports certain properties, which, if left unmitigated, can allow an attacker to execute arbitrary code from a hacker-controlled malicious MySQL server within Kylin server processes. This issue affects Apache Kylin 2 version 2.6.6 and prior versions; Apache Kylin 3 version 3.1.2 and prior versions.
Apache Kylin 2.0.0, 2.1.0, 2.2.0, 2.3.0, 2.3.1, 2.3.2, 2.4.0, 2.4.1, 2.5.0, 2.5.1, 2.5.2, 2.6.0, 2.6.1, 2.6.2, 2.6.3, 2.6.4, 2.6.5, 2.6.6, 3.0.0-alpha, 3.0.0-alpha2, 3.0.0-beta, 3.0.0, 3.0.1, 3.0.2, 3.1.0, 4.0.0-alpha has one restful api which exposed Kylin's configuration information without any authentication, so it is dangerous because some confidential information entries will be disclosed to everyone.
Improper Handling of Insufficient Permissions or Privileges vulnerability in Apache Kylin. Improper authorization in job information retrieval, where an attacker may get access to unauthorized jobs in other projects.
This issue affects Apache Kylin: from 4 through 5.0.3.
Users are recommended to upgrade to version 5.0.4, which fixes the issue.
