The vulnerability exists due to incorrect default permissions for files located in the temporary directory set by the Guava com.google.common.io.Files.createTempDir(). A local user with access to the system can view contents of files and directories or modify them.
2) Improper input validation (CVE-ID: CVE-2021-28170)
The vulnerability allows a remote non-authenticated attacker to manipulate data.
The vulnerability exists due to improper input validation within the Policy (Jakarta) component in Oracle Communications Cloud Native Core Policy. A remote non-authenticated attacker can exploit this vulnerability to manipulate data.
3) Cross-site scripting (CVE-ID: CVE-2021-41184)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of values passed to the `of` option. A remote attacker can execute arbitrary JavaScript code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
4) Improper input validation (CVE-ID: CVE-2022-21453)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
The vulnerability exists due to improper input validation within the Console component in Oracle WebLogic Server. A remote non-authenticated attacker can exploit this vulnerability to read and manipulate data.
5) Infinite loop (CVE-ID: CVE-2022-23437)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop when parsing XML documents. A remote attacker can supply a specially crafted XML document, consume all available system resources and cause denial of service conditions.
6) Improper input validation (CVE-ID: CVE-2022-21441)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper input validation within the Core component in Oracle WebLogic Server. A remote non-authenticated attacker can exploit this vulnerability to perform a denial of service (DoS) attack.
7) SQL injection (CVE-ID: CVE-2022-23305)
The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.
The vulnerability exists due to insufficient sanitization of user-supplied data in the JDBCAppender. A remote attacker can send a specially crafted request to the affected application and execute arbitrary SQL commands within the application database.
Note, a non-default configuration with enabled JDBCAppender is required to exploit the vulnerability.
