Description
This security bulletin contains information about 9 vulnerabilities.
1) Use of Hard-coded Cryptographic Key (CVE-ID: CVE-2020-11487)
CWE-ID: CWE-321 - Use of Hard-coded Cryptographic Key
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to usage of a hard-coded RSA 1024 key with weak ciphers in the AMI BMC firmware. A remote attacker can gain unauthorized access to sensitive information on the system.
2) Use of hard-coded credentials (CVE-ID: CVE-2020-11483)
CWE-ID: CWE-798 - Use of Hard-coded Credentials
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to gain full access to vulnerable system.
The vulnerability exists due to presence of hard-coded credentials in application code in the AMI BMC firmware. A remote unauthenticated attacker can access the affected system using the hard-coded credentials.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Information disclosure (CVE-ID: CVE-2020-11484)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application. A local administrator can obtain the hash of the BMC/IPMI user password.
4) Cross-site request forgery (CVE-ID: CVE-2020-11485)
CWE-ID: CWE-352 - Cross-Site Request Forgery (CSRF)
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to perform cross-site request forgery attacks.
The vulnerability exists due to insufficient validation of the HTTP request origin. A remote attacker can trick the victim to visit a specially crafted web page and perform arbitrary actions on behalf of the victim on the vulnerable website.
5) Arbitrary file upload (CVE-ID: CVE-2020-11486)
CWE-ID: CWE-434 - Unrestricted Upload of File with Dangerous Type
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/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 attacker to compromise vulnerable system.
The vulnerability exists due to insufficient validation of file during file upload. A remote attacker can upload or transfer files that can be automatically processed within the product's environment, which may lead to remote code execution.
6) Security Features (CVE-ID: CVE-2020-11488)
CWE-ID: CWE-254 - Security Features
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to compromise the target system.
The vulnerability exists due to the affected software does not validate the RSA 1024 public key used to verify the firmware signature. A local administrator can cause information disclosure or arbitrary code execution.
7) Information disclosure (CVE-ID: CVE-2020-11489)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to default SNMP community strings are used in the AMI BMC firmware. A remote attacker can gain unauthorized access to sensitive information on the system.
8) Use of Hard-coded Cryptographic Key (CVE-ID: CVE-2020-11615)
CWE-ID: CWE-321 - Use of Hard-coded Cryptographic Key
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to usage of a hard-coded RC4 cipher key in the AMI BMC firmware. A remote attacker can gain unauthorized access to sensitive information on the system.
9) Cryptographic issues (CVE-ID: CVE-2020-11616)
CWE-ID: CWE-310 - Cryptographic Issues
CVSSv4: CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to the Pseudo-Random Number Generator (PRNG) algorithm used in the JSOL package that implements the IPMI protocol is not cryptographically strong. A remote attacker on the local network can gain unauthorized access to sensitive information on the system.
