CVE-2024-6119 is a high-severity vulnerability affecting OpenSSL, with a CVSS score of 7.5. This vulnerability allows applications that perform certificate name checks, such as TLS clients validating server certificates, to attempt to read an invalid memory address. This leads to abnormal termination of the application process, resulting in a denial of service. The risk to organizations includes potential disruptions to critical services, making immediate remediation essential.
The vulnerability primarily affects applications that specify an expected DNS name, Email address, or IP address in their certificate checks. Basic certificate chain validation remains unaffected, but the potential for service interruptions necessitates swift action. Given the severity level, organizations should prioritize patching immediately.
With no known exploits currently available and a lack of high-profile cases, the situation remains stable; however, vigilance is crucial. The OpenSSL community has acknowledged the issue and is actively working on a fix, which should be applied as part of standard security practices.
Organizations using affected OpenSSL versions, particularly those integrated with other NetApp products, should evaluate their environments for potential impacts and prepare for timely updates.
Vulnerability Details
The vulnerability allows applications performing certificate name checks to read invalid memory addresses, resulting in abnormal termination of the application process. This vulnerability's CVSS score of 7.5 indicates a high severity, highlighting the critical nature of the risk involved. Affected components include various firmware and management services from NetApp, as well as OpenSSL itself.
The vulnerability was published on September 3, 2024, and is classified under CWE-843. Organizations using OpenSSL versions between 3.0.0 and 3.3.2 are particularly vulnerable, and immediate action should be taken to mitigate risks.
Technical Analysis
The root cause of CVE-2024-6119 lies in the handling of certificate name checks within OpenSSL. When an application attempts to compare an expected name against an 'otherName' subject alternative name in an X.509 certificate, it may encounter an invalid memory access. This vulnerability has a low attack complexity, requires no privileges, and does not necessitate user interaction, making it accessible to potential attackers.
The attack vector for this vulnerability is classified as NETWORK, indicating that it could be exploited remotely. The impact on availability is significant, as it can lead to a denial of service, while confidentiality and integrity are not affected.
Risk & Impact Analysis
The real-world risk associated with CVE-2024-6119 is substantial, particularly for organizations relying heavily on OpenSSL for secure communications. The potential for denial of service could disrupt critical operations, impacting productivity and service delivery. Given the high CVSS score, organizations should assess their exposure and prioritize remediation in their security cycle.
The urgency for remediation is rated as high. Organizations should schedule updates and apply patches as soon as they are available to mitigate the risk of exploitation. The availability impact is significant, highlighting the necessity for immediate attention to this vulnerability.
