Description
This security bulletin contains information about 10 secuirty vulnerabilities.
1) Improper input validation (CVE-ID: CVE-2023-21841)
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
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 gain access to sensitive information.
2) Improper input validation (CVE-ID: CVE-2023-21839)
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
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 gain access to sensitive information.
3) Code Injection (CVE-ID: CVE-2023-21838)
The vulnerability allows a remote non-authenticated attacker to compromise the affected system.
The vulnerability exists due to improper input validation within the ForeignOpaqueReference class. A remote non-authenticated attacker can perform JNDI injection and execute arbitrary Java code on the system.4) Improper input validation (CVE-ID: CVE-2023-21837)
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
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 gain access to sensitive information.
5) Improper input validation (CVE-ID: CVE-2023-21842)
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
The vulnerability exists due to improper input validation within the Web Container component in Oracle WebLogic Server. A remote non-authenticated attacker can exploit this vulnerability to gain access to sensitive information.
6) Deserialization of Untrusted Data (CVE-ID: CVE-2022-25647)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to insecure input validation when processing serialized data passed to writeReplace() method. A remote attacker can pass specially crafted data to the application and perform a denial of service attack.
7) Improper input validation (CVE-ID: CVE-2022-40153)
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 Centralized Third Party Jars (XStream) component in Oracle WebLogic Server. A remote non-authenticated attacker can exploit this vulnerability to perform a denial of service (DoS) attack.
8) Resource exhaustion (CVE-ID: CVE-2022-40150)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources when processing untrusted XML or JSON data. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
9) Out-of-bounds write (CVE-ID: CVE-2022-42920)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input within the API. A remote attacker can create a specially crafted request to the affected application, trigger an out-of-bounds write and execute arbitrary code on the target system.
10) Deserialization of untrusted data (CVE-ID: CVE-2018-7489)
The vulnerability allows a remote unauthenticated attacker to bypass security restrictions and execute arbitrary code on the target system.The weakness exists in the readValue method due to improper validation of user-input. A remote attacker can send malicious JSON input, bypass security restrictions and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
