SB2024041658 - Multiple vulnerabilities in Oracle Communications Cloud Native Core Network Data Analytics Function

Description

This security bulletin contains information about 6 secuirty vulnerabilities.

1) Improper input validation (CVE-ID: CVE-2023-6507)

The vulnerability allows a remote privileged user to manipulate data.

The vulnerability exists due to improper input validation within the Third Party (Python) component in Oracle Communications Cloud Native Core Network Data Analytics Function. A remote privileged user can exploit this vulnerability to manipulate data.

2) Input validation error (CVE-ID: CVE-2023-34055)

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 in Web Observations. A remote attacker can send specially crafted HTTP requests to the application and perform a denial of service (DoS) attack.

Successful exploitation of the vulnerability requires that application is using Spring MVC or Spring WebFlux and that org.springframework.boot:spring-boot-actuator is on the classpath.

3) Input validation error (CVE-ID: CVE-2024-22233)

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 attacker can send specially crafted HTTP requests to the application and perform a denial of service (DoS) attack.

4) NULL pointer dereference (CVE-ID: CVE-2023-49083)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error when calling the load_pem_pkcs7_certificates() or load_der_pkcs7_certificates() functions. A remote attacker can pass specially crafted PKCS7 blob/certificate certificate to the application and perform a denial of service (DoS) attack.

5) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2023-46589)

The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.

The vulnerability exists due to improper validation of HTTP requests when parsing malformed trailer headers. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.

Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.

6) Heap-based buffer overflow (CVE-ID: CVE-2023-41056)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when resizing memory buffers. A remote attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
