CVE-2022-37454 is a critical vulnerability affecting the Keccak XKCP SHA-3 reference implementation. This vulnerability allows attackers to exploit an integer overflow, leading to a buffer overflow that can enable arbitrary code execution. Additionally, this flaw can compromise the expected cryptographic properties of the affected systems. Given the severity of the vulnerability, organizations should prioritize patching immediately.
The vulnerability has a CVSS score of 9.8, categorized as CRITICAL, indicating a high level of risk to systems utilizing this implementation. The attack vector is network-based, with low complexity and no privileges or user interaction required. This makes it particularly dangerous, as attackers can exploit it remotely without any special access.
The potential impacts of CVE-2022-37454 are severe. Organizations running vulnerable versions of the Keccak implementation could face unauthorized access, data integrity issues, and service availability disruptions. With the increasing reliance on cryptographic functions in various applications, the urgency for organizations to address this vulnerability cannot be overstated.
As of now, there are no known public exploits or proof of concept (PoC) code available for CVE-2022-37454. However, the critical nature of this vulnerability suggests that it could be targeted in future attacks. Organizations should implement defensive measures, including immediate patching and continuous monitoring.
Vulnerability Details
The vulnerability is primarily characterized by an integer overflow within the Keccak XKCP SHA-3 reference implementation prior to the commit fdc6fef. This defect manifests in the sponge function interface, allowing attackers to execute arbitrary code or corrupt cryptographic properties.
The CVSS 3.1 vector string for this vulnerability is CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, indicating a high likelihood of significant impacts across confidentiality, integrity, and availability. The vulnerability affects multiple products including extended_keccak_code_package, debian_linux, fedora, php, python, and others.
The vulnerability was published on October 21, 2022, and is classified under CWE-190 (Integer Overflow or Wraparound). Organizations should reference the published advisories and apply relevant patches to mitigate the risks associated with this vulnerability.
Technical Analysis
The root cause of CVE-2022-37454 stems from an integer overflow in the Keccak SHA-3 implementation. This overflow can lead to a buffer overflow, allowing attackers to manipulate the memory allocation of the application. As a result, arbitrary code can be executed, potentially compromising the entire system.
The attack vector is primarily network-based, posing a low complexity for potential exploits. Importantly, there are no privileges required to exploit this vulnerability, and user interaction is not necessary. This allows attackers to execute their payloads remotely with minimal effort.
The impacts on confidentiality, integrity, and availability are significant, making this vulnerability a critical security concern. Organizations must take immediate action to secure affected systems by applying patches and implementing robust monitoring solutions.
Risk & Impact Analysis
Organizations operating systems with the Keccak SHA-3 implementation are at high risk due to this vulnerability. The ability for an attacker to execute arbitrary code remotely without requiring elevated privileges presents a significant threat. The potential blast radius includes not just the immediate system but also any connected systems that rely on the cryptographic functions provided by the vulnerable implementation.
Given the critical nature of this vulnerability, organizations should prioritize remediation efforts. The urgency is underscored by the CVSS score of 9.8 and the potential for exploitation in the wild. Regular assessments and updates to security policies should be implemented to mitigate future risks.
