Description
This security bulletin contains information about 11 secuirty vulnerabilities.
1) Incorrect default permissions (CVE-ID: CVE-2020-8908)
The vulnerability allows a local user to escalate privileges on the system.
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-2023-22031)
The vulnerability allows a remote privileged user 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 privileged user can exploit this vulnerability to perform a denial of service (DoS) attack.
3) Information disclosure (CVE-ID: CVE-2021-28168)
The vulnerability allows a local attacker to gain access to potentially sensitive information.
The vulnerability exists due to the use of the File.createTempFile which creates a file inside of the system temporary directory with the permissions: -rw-r--r--. A local attacker can gain unauthorized access to sensitive information on the system.
4) Improper input validation (CVE-ID: CVE-2023-22040)
The vulnerability allows a remote privileged user to damange or delete data.
The vulnerability exists due to improper input validation within the Core component in Oracle WebLogic Server. A remote privileged user can exploit this vulnerability to damange or delete data.
5) Input validation error (CVE-ID: CVE-2023-20863)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input. A remote user can use a specially crafted SpEL expression and perform a denial of service (DoS) attack.
6) Improper input validation (CVE-ID: CVE-2022-24409)
The vulnerability allows a remote authenticated user to execute arbitrary code.
The vulnerability exists due to improper input validation within the Centralized Thirdparty Jars (BSAFE SSL-J) component in Oracle WebLogic Server. A remote authenticated user can exploit this vulnerability to execute arbitrary code.
7) Input validation error (CVE-ID: CVE-2023-20860)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to an input validation error caused by using the wildcard ("**") as a pattern in Spring Security configuration with the mvcRequestMatcher, which creates a mismatch in pattern matching between Spring Security and Spring MVC. A remote attacker can bypass certain security restrictions.
8) Code Injection (CVE-ID: CVE-2022-42890)
The vulnerability allows a remote user to gain access to sensitive information.
The vulnerability exists due to the application allows running Java classes via JavaScript. A remote user can use JavaScript to execute a Java class on the system and obtain its execution results.
Example:
Runtime.getRuntime().exec("xxx");
9) Uncontrolled Recursion (CVE-ID: CVE-2023-1370)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to uncontrolled recursion when processing nested arrays and objects. A remote attacker can pass specially crafted JSON data to the application and perform a denial of service (DoS) attack.
10) Uncontrolled Recursion (CVE-ID: CVE-2023-1436)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to uncontrolled recursion when constructing a JSONArray from a Collection that contains a self-reference in one of its elements. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
11) Code Injection (CVE-ID: CVE-2023-26119)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to improper input validation when parsing XSTL code. A remote attacker can trick the victim to open a specially crafted web page and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
