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 …
In the fix for CVE-2022-24697, a block list 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.
Diagnosis Controller miss parameter validation, so user may attacked by command injection via HTTP Request.
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.
Kylin can receive user input and load any class through Class.forName(…). This issue affects Apache Kylin 2 and prior versions; Apache Kylin 3 and prior versions; Apache Kylin 4 and prior versions.
All request mappings in StreamingCoordinatorController.java handling /kylin/api/streaming_coordinator/* REST API endpoints does 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
In Apache Kylin, Cross-origin requests with credentials are allowed to be sent from any origin. This issue affects Apache Kylin 2 and prior versions; Apache Kylin 3 and prior versions; Apache Kylin 4 and prior versions.
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 and prior versions; Apache Kylin 3 and …
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 Kyl
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 and prior versions; Apache Kylin 3 and prior versions.
Apache Kylin 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.
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.
Similar to CVE-2020-1956, Kylin has one more restful API which concatenates the API inputs into OS commands and 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.
Apache Kylin 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.
