CVE-2024-45844 is a high-severity vulnerability affecting multiple F5 BIG-IP products, including big-ip_access_policy_manager and big-ip_advanced_firewall_manager. This vulnerability allows an attacker to bypass access control restrictions, regardless of the port lockdown settings. Given its CVSS score of 8.6, organizations should prioritize patching immediately.
The vulnerability affects various components of the BIG-IP technology stack, including big-ip_application_security_manager and big-ip_ssl_orchestrator. The risk to organizations includes unauthorized access to sensitive applications and data, which can lead to serious security breaches.
As of the publication date, there are no known exploits for this vulnerability. However, the potential for exploitation remains high, and organizations must remain vigilant in their security practices.
Organizations utilizing affected F5 BIG-IP products are strongly encouraged to address this vulnerability in their patch management processes and ensure that their systems are updated to mitigate potential threats.
Vulnerability Details
The official description states that the BIG-IP monitor functionality may allow an attacker to bypass access control restrictions, regardless of the port lockdown settings. Software versions that have reached End of Technical Support (EoTS) are not evaluated for this vulnerability.
The vulnerability is classified under CWE-306, which pertains to missing authentication for critical resources. The CVSS 4.0 vector indicates that the attack vector is network-based, the attack complexity is low, and high privileges are required for exploitation.
Organizations should be aware that the confidentiality, integrity, and availability impacts are all rated as high. This highlights the significant risk associated with this vulnerability.
Technical Analysis
The root cause of CVE-2024-45844 stems from improper access controls in the BIG-IP monitor functionality. Attackers may leverage this weakness to gain unauthorized access to systems, potentially leading to data breaches or further exploitation of connected resources.
The attack vector is categorized as NETWORK, meaning that an attacker could exploit this vulnerability remotely without physical access to the affected systems. The attack complexity is low, suggesting that minimal effort is required to exploit the weakness. Privileges required for exploitation are high, which means that an attacker would need significant access to the system to carry out the attack.
User interaction is not required, which further increases the risk of successful exploitation. The impacts on confidentiality, integrity, and availability are all rated high, indicating that any exploitation could result in severe consequences for affected organizations.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to critical systems and sensitive data, leading to potential data breaches and compliance violations. The high CVSS score reflects the serious nature of this vulnerability and the urgency for organizations to implement necessary patches and updates.
The potential blast radius for this vulnerability is significant, as it affects a wide range of F5 BIG-IP products. Organizations must assess their deployment of these products and prioritize remediation efforts accordingly.
Given the current exploitability status, organizations should remain proactive in their security posture, continuously monitoring for any signs of attempted exploitation.
