Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Input validation error (CVE-ID: CVE-2022-26520)
The vulnerability allows a remote attacker to create arbitrary files on the system.
The vulnerability exists due to insufficient validation of user-supplied input when handling jdbc URL or its properties. A remote attacker can call java.util.logging.FileHandler to write to arbitrary files through the loggerFile and loggerLevel connection properties.
Successful exploitation of the vulnerability may allow an attacker to create and executable arbitraru JSP file under a Tomcat web root.
2) Improper initialization (CVE-ID: CVE-2022-21724)
The vulnerability allows a remote attacker to escalate privileges on the system.
The vulnerability exists due to improper initialization in pgjdbc driver when handling attacker-controlled URL in connection properties as the driver does not verify if the class implements the expected interface before instantiating the class. A remote attacker can pass specially crafted URL to the affected application and execute arbitrary code in the system.
3) SQL injection (CVE-ID: CVE-2022-31197)
The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.
The vulnerability exists due to insufficient sanitization of user-supplied data within the java.sql.ResultRow.refreshRow() method when processing column names. A remote attacker can send a specially crafted request to the affected application and execute arbitrary SQL commands within the application database using the statement terminator, e.g." ;".
Successful exploitation of this vulnerability may allow a remote attacker to read, delete, modify data in database and gain complete control over the affected application.
4) XML External Entity injection (CVE-ID: CVE-2020-13692)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insufficient validation of user-supplied XML input. A remote attacker can pass a specially crafted XML code to the affected application and view contents of arbitrary files on the system or initiate requests to external systems.
Successful exploitation of the vulnerability may allow an attacker to view contents of arbitrary file on the server or perform network scanning of internal and external infrastructure.
5) Incorrect default permissions (CVE-ID: CVE-2022-41946)
The vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to application stores files with sensitive information in system's temporary directory. A local user can read the files and gain access to sensitive information.
