SB2024011662 - Multiple vulnerabilities in Oracle Communications Cloud Native Core Unified Data Repository

Description

This security bulletin contains information about 5 vulnerabilities.

1) Insufficient entropy (CVE-ID: CVE-2023-31582)

CWE-ID: CWE-331 - Insufficient Entropy

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to brute-force JWT token.

The vulnerability exists due to usage of insufficient entropy when generating JWT token. A remote attacker can brute-force the JWT token and gain unauthorized access to the application.

2) Infinite loop (CVE-ID: CVE-2023-1108)

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green

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

The vulnerability exists due to infinite loop caused by an unexpected handshake status updated in SslConduit. A remote attacker can consume all available system resources and cause denial of service conditions.

3) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2023-5072)

CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green

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

The vulnerability exists due to allocation of resources without limits or throttling. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.

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

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:A/U:Amber

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.

5) Improper input validation (CVE-ID: CVE-2023-22102)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

The vulnerability exists due to improper input validation within the Connector/J component in MySQL Connectors. A remote non-authenticated attacker can exploit this vulnerability to execute arbitrary code.
