A vulnerability was found in the Hot Rod client. This security issue occurs as the Hot Rod client does not enable hostname validation when using TLS, possibly resulting in a man-in-the-middle (MITM) attack. The CVSS score for this vulnerability is 7.4, classified as high severity, indicating significant risk to affected organizations.
Risk to organizations includes potential unauthorized access to sensitive information, as attackers may leverage this vulnerability to intercept and manipulate communications. Given the nature of the vulnerability, organizations should prioritize patching immediately to reduce exposure to this risk.
Currently, it is confirmed that no public exploit exists in the Exploit Database, but there are reports of GitHub PoCs related to this CVE. Organizations should remain vigilant and monitor their systems for any unusual activity associated with this vulnerability.
To ensure security, organizations using the affected products must take immediate action to apply the necessary patches and updates. The urgency of this vulnerability requires that remediation efforts be scheduled as a top priority.
Vulnerability Details
The vulnerability, identified as CVE-2023-4586, affects the Hot Rod client from Red Hat. The main issue stems from the lack of hostname validation during TLS usage. This oversight can lead to a man-in-the-middle (MITM) attack, allowing an attacker to intercept or alter communications between the client and the server.
The vulnerability has a CVSS score of 7.4, indicating a high severity level. The attack vector is categorized as network-based, with high complexity required for successful exploitation. Importantly, no privileges or user interaction are needed.
The vulnerability affects the following products: Red Hat Data Grid version 8.0.0 and the Infinispan Hot Rod client. Published on October 4, 2023, this vulnerability has been classified under CWE-20 (Improper Input Validation) and CWE-295 (Improper Certificate Validation).
Technical Analysis
The root cause of this vulnerability lies in the Hot Rod client's failure to validate hostnames when establishing TLS connections. This flaw opens the door for attackers to perform MITM attacks. The attack vector is network-based, meaning attackers can exploit this vulnerability remotely. The complexity of the attack is classified as high, indicating that a sophisticated approach is necessary for exploitation.
No privileges are required for exploitation, and user interaction is also not necessary, making this vulnerability particularly dangerous. The impact on confidentiality and integrity is high, while availability remains unaffected.
Risk & Impact Analysis
This vulnerability poses a significant risk to organizations utilizing the affected Hot Rod client. The potential for a MITM attack means that attackers could gain unauthorized access to sensitive data transmitted over TLS connections. Organizations using these products must consider the implications of heightened risk exposure and the potential fallout from a successful attack.
The blast radius for this vulnerability can be extensive, especially in environments where sensitive data is transmitted. Organizations should assess their deployment and the implications of this vulnerability on their overall security posture. Given its high CVSS score and the possibility of exploitation, this vulnerability should be treated with urgency.
