SB2024041656 - Multiple vulnerabilities in Oracle Communications Cloud Native Core Unified Data Repository

Description

This security bulletin contains information about 7 secuirty vulnerabilities.

1) Resource exhaustion (CVE-ID: CVE-2024-26308)

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 memory when unpacking a broken Pack200 file. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.

2) Inadequate encryption strength (CVE-ID: CVE-2023-48795)

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to incorrect implementation of the SSH Binary Packet Protocol (BPP), which mishandles the handshake phase and the use of sequence numbers. A remote attacker can perform MitM attack and delete the SSH2_MSG_EXT_INFO message sent before authentication starts, allowing the attacker to disable a subset of the keystroke timing obfuscation features introduced in OpenSSH 9.5.

The vulnerability was dubbed "Terrapin attack" and it affects both client and server implementations.

3) 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.

4) Resource exhaustion (CVE-ID: CVE-2023-51775)

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. A remote attacker can trigger resource exhaustion via large p2c (aka PBES2 Count) value and perform a denial of service (DoS) attack.

5) 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.

6) 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.

7) Out-of-bounds write (CVE-ID: CVE-2023-51257)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input within the jas_icctxt_input() function in jas_icc.c. A remote attacker can create a specially crafted file, trick the victim into opening it using the affected software, trigger an out-of-bounds write and execute arbitrary code on the target system.
