CVE-2021-1134 (GCVE-0-2021-1134)
Vulnerability from cvelistv5 – Published: 2021-06-29 03:05 – Updated: 2024-11-07 22:07
VLAI
Title
Cisco DNA Center Certificate Validation Vulnerability
Summary
A vulnerability in the Cisco Identity Services Engine (ISE) integration feature of the Cisco DNA Center Software could allow an unauthenticated, remote attacker to gain unauthorized access to sensitive data. The vulnerability is due to an incomplete validation of the X.509 certificate used when establishing a connection between DNA Center and an ISE server. An attacker could exploit this vulnerability by supplying a crafted certificate and could then intercept communications between the ISE and DNA Center. A successful exploit could allow the attacker to view and alter sensitive information that the ISE maintains about clients that are connected to the network.

Title
Cisco Data Center Network Manager Certificate Validation Vulnerabilities
Summary
Multiple vulnerabilities in Cisco Data Center Network Manager (DCNM) could allow an attacker to spoof a trusted host or construct a man-in-the-middle attack to extract sensitive information or alter certain API requests. These vulnerabilities are due to insufficient certificate validation when establishing HTTPS requests with the affected device. For more information about these vulnerabilities, see the Details section of this advisory.

Cisco Unified Computing System Central Software Improper Certificate Validation Vulnerability
Summary
A vulnerability in the certificate registration process of Cisco Unified Computing System (UCS) Central Software could allow an authenticated, adjacent attacker to register a rogue Cisco Unified Computing System Manager (UCSM). This vulnerability is due to improper certificate validation. An attacker could exploit this vulnerability by sending a crafted HTTP request to the registration API. A successful exploit could allow the attacker to register a rogue Cisco UCSM and gain access to Cisco UCS Central Software data and Cisco UCSM inventory data.

CVE-2021-20230 (GCVE-0-2021-20230)
Vulnerability from cvelistv5 – Published: 2021-02-23 16:34 – Updated: 2024-08-03 17:30
VLAI
Summary
A flaw was found in stunnel before 5.57, where it improperly validates client certificates when it is configured to use both redirect and verifyChain options. This flaw allows an attacker with a certificate signed by a Certificate Authority, which is not the one accepted by the stunnel server, to access the tunneled service instead of being redirected to the address specified in the redirect option. The highest threat from this vulnerability is to confidentiality.
Severity
No CVSS data available.

Mitigation
Phases: Architecture and Design, Implementation
Description:
- Certificates should be carefully managed and checked to assure that data are encrypted with the intended owner's public key.
Mitigation
Phase: Implementation
Description:
- If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the hostname.
CAPEC-459: Creating a Rogue Certification Authority Certificate
An adversary exploits a weakness resulting from using a hashing algorithm with weak collision resistance to generate certificate signing requests (CSR) that contain collision blocks in their "to be signed" parts. The adversary submits one CSR to be signed by a trusted certificate authority then uses the signed blob to make a second certificate appear signed by said certificate authority. Due to the hash collision, both certificates, though different, hash to the same value and so the signed blob works just as well in the second certificate. The net effect is that the adversary's second X.509 certificate, which the Certification Authority has never seen, is now signed and validated by that Certification Authority.
CAPEC-475: Signature Spoofing by Improper Validation
An adversary exploits a cryptographic weakness in the signature verification algorithm implementation to generate a valid signature without knowing the key.
