SB20241015114 - Multiple vulnerabilities in Oracle Blockchain Platform

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) Incorrect default permissions (CVE-ID: CVE-2023-2976)

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

The vulnerability exists due to incorrect default permissions in com.google.common.io.FileBackedOutputStream. A local user with access to the system can view contents of files and directories or modify them.

4) Information disclosure (CVE-ID: CVE-2024-28849)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to credentials are shared via headers when following cross-domain redirects. A remote attacker can gain access to sensitive information.

5) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2024-22020)

The disclosed vulnerability allows a remote user to perform SSRF attacks.

The vulnerability exists due to insufficient validation of user-supplied input when handling non-network imports in data URLs. A remote user can bypass network import restrictions and execute arbitrary code.

6) Resource exhaustion (CVE-ID: CVE-2023-45288)

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

The vulnerability exists due to insufficient limitations placed on the amount of CONTINUATION frames that can be sent within a single HTTP/2 stream. A remote attacker can send specially crafted HTTP/2 requests to the server and perform a denial of service (DoS) attack.

7) Resource exhaustion (CVE-ID: CVE-2023-44487)

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

The vulnerability exists due to improperly control of consumption for internal resources when handling HTTP/2 requests with compressed HEADERS frames. A remote attacker can send a sequence of compressed HEADERS frames followed by RST_STREAM frames and perform a denial of service (DoS) attack, a.k.a. "Rapid Reset".

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