OpenSSL Certificate Validation Vulnerability
OpenSSL contains a vulnerability that could allow an attacker to use a valid non-certificate authority (CA) certificate to act as a CA and sign a certificate for an arbitrary organization, user, or device.
The vulnerability is due to a bypassed check in the validation logic of X.509 certificate chains, resulting in the affected system accepting as valid certificates signed by a non-CA certificate or certificate chain. An attacker can exploit this vulnerability by using any valid certificate or certificate chain to sign a crafted certificate. A successful exploit could allow the attacker to conduct a main-in-the-middle (MiTM) attack and obtain sensitive information (or misreport information) or impersonate an organization, user, or device. Exploitation of this vulnerability could also allow attackers to access networks or assets that are protected by certificate authentication.
This vulnerability has been assigned the following CVE ID:
- CVE-2021-3450
OpenSSL NULL Pointer Dereference Denial of Service Vulnerability
OpenSSL contains a vulnerability that could allow an attacker to cause a denial of service (DoS) condition on a targeted system.
The vulnerability exists because the affected software incorrectly handles memory structures, leading to a NULL pointer dereference. An attacker could exploit the vulnerability by submitting crafted Transport Layer Security (TLS) packets to an interface of an affected device. A successful exploit could allow the attacker to cause a crash of the TLS server process which could result in a DoS condition on the targeted device.
Note: Only servers that are processing incoming TLSv1.2 packets are affected by this vulnerability.
This vulnerability has been assigned the following CVE ID:
- CVE-2021-3449
-
Any workarounds will be documented in the product-specific Cisco bugs, which are identified in the Vulnerable Products section of this advisory.
-
For information about fixed software releases, consult the Cisco bugs identified in the Vulnerable Products section of this advisory.
When considering software upgrades, customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories page, to determine exposure and a complete upgrade solution.
In all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers.
-
On March 25, 2021, the OpenSSL Project released OpenSSL Security Advisory [25 March 2021] detailing these vulnerabilities.
The Cisco Product Security Incident Response Team (PSIRT) is aware that proof-of-concept exploit code is available for the vulnerability that is described in this advisory and identified by CVE-2021-3449. Cisco PSIRT is not aware of any malicious use of this vulnerability (CVE-2021-3449).
Cisco PSIRT is not aware of exploit code for or any malicious use of the vulnerability identified by CVE-2021-3450.
