SB2022071957 - Multiple vulnerabilities in Oracle Communications Cloud Native Core Binding Support Function

Description

This security bulletin contains information about 7 secuirty vulnerabilities.

1) Security features bypass (CVE-ID: CVE-2022-24329)

The vulnerability allows a remote user to bypass certain security restrictions.

The vulnerability exists due to unspecified error, related to the ability to lock dependencies for Kotlin Multiplatform Gradle projects.

2) Use-after-free (CVE-ID: CVE-2022-23308)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error when processing ID and IDREF attributes in valid.c. A remote attacker can pass specially crafted XML input to the application, trigger a use-after-free error and crash the application or execute arbitrary code on the system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.

3) Out-of-bounds write (CVE-ID: CVE-2020-36518)

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

The vulnerability exists due to a boundary error when processing untrusted input. A remote attacker can trigger out-of-bounds write and cause a denial of service condition on the target system.

4) Heap-based buffer overflow (CVE-ID: CVE-2022-25636)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error in net/netfilter/nf_dup_netdev.c in the Linux kernel, related to nf_tables_offload. A local user can trigger a heap-based buffer overflow and execute arbitrary code with elevated privileges.

5) Buffer overflow (CVE-ID: CVE-2022-23219)

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

The vulnerability exists due to a boundary error within the clnt_create() function in the sunrpc module. A remote attacker can pass specially crafted input to the application that is using the affected library version, trigger memory corruption and execute arbitrary code on the target system.

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

6) Code Injection (CVE-ID: CVE-2022-22965)

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

The vulnerability exists due to improper input validation. A remote attacker can send a specially crafted HTTP request to the affected application and execute arbitrary code on the target system.

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

Note, the vulnerability is being actively exploited in the wild.

This vulnerability was dubbed "Spring4Shell".

7) Code Injection (CVE-ID: CVE-2022-22947)

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

The vulnerability exists due to a code injection attack when the Gateway Actuator endpoint is enabled. A remote attacker can send a specially crafted HTTP POST request and execute arbitrary code on the target system.

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