CVE-2022-41983 is a low-severity vulnerability affecting F5 BIG-IP products. This vulnerability allows data to be transmitted unencrypted under specific conditions, even when an SSL Profile is applied. The severity is classified as low with a CVSS score of 3.7, which indicates that while the risk is present, it may not be immediately exploitable. Organizations should prioritize patching as this could lead to unauthorized data exposure.
The vulnerability affects specific versions of BIG-IP, including versions 16.1.x before 16.1.3.1, 15.1.x before 15.1.7, 14.1.x before 14.1.5.1, and all versions of 13.1.x. Organizations using these versions should take immediate action to mitigate risks.
Given the potentially sensitive nature of data that may be transmitted unencrypted, organizations should assess their exposure and implement necessary mitigations. The urgency for defenders is moderate, as the nature of the risk is primarily related to data confidentiality.
Organizations are encouraged to review their environments, especially those utilizing Intel QAT (QuickAssist Technology) with AES-GCM/CCM cipher. Failure to address this vulnerability could result in significant risks.
Risk to organizations includes unauthorized data exposure. Prompt action is recommended to patch affected systems and avoid potential data breaches.
In summary, while the CVSS score indicates a low severity, the implications of unencrypted data transmission should not be underestimated. Organizations must take steps to ensure the security of their data.
Vulnerability Details
The official description of CVE-2022-41983 states that on specific hardware platforms, on BIG-IP versions 16.1.x before 16.1.3.1, 15.1.x before 15.1.7, 14.1.x before 14.1.5.1, and all versions of 13.1.x, while Intel QAT (QuickAssist Technology) and the AES-GCM/CCM cipher is in use, undisclosed conditions can cause BIG-IP to send data unencrypted even with an SSL Profile applied.
This vulnerability is categorized under CWE-319, indicating a lack of encryption in the transmission of sensitive data. The CVSS version 3.1 score is 3.7, which places it in the low severity category, with implications for data confidentiality.
Affected product versions include multiple F5 components such as BIG-IP Access Policy Manager, Advanced Firewall Manager, and others. Organizations using these products should verify their versions and apply necessary patches.
Technical Analysis
The root cause of CVE-2022-41983 lies in the conditions that exist when using Intel QAT with specific ciphers. The attack vector is network-based, requiring low privileges and no user interaction, which increases the potential for exploitation.
The attack complexity is high, indicating that specific conditions and configurations must exist for an attacker to successfully exploit the vulnerability. However, the implications of successful exploitation could result in low confidentiality impact, as data may be transmitted unencrypted.
There is no integrity or availability impact associated with this vulnerability, but the potential for confidential data exposure remains a significant concern.
Risk & Impact Analysis
The real-world deployment risk of CVE-2022-41983 is primarily associated with the potential for unencrypted data transmission. If attackers can exploit this vulnerability, they may gain access to sensitive information that is transmitted without encryption.
Organizations using vulnerable versions of BIG-IP should assess their configurations and ensure they are compliant with security best practices to mitigate this risk. The blast radius of this vulnerability can be significant if unencrypted data is intercepted.
Urgency for remediation is moderate, and organizations should schedule updates in their patch cycles to address this vulnerability promptly.

Affected Versions
Affected versions include F5 BIG-IP Access Policy Manager, Advanced Firewall Manager, Advanced Web Application Firewall, and several others. Specifically, versions prior to 16.1.3.1, 15.1.7, 14.1.5.1, and all versions of 13.1.x are vulnerable.
Mitigation & Remediation
Organizations should apply the latest patches provided by F5 to remediate this vulnerability. The vendor has recommended updating to the following versions: 16.1.3.1 or newer, 15.1.7 or newer, and 14.1.5.1 or newer.
In cases where immediate patching is not feasible, consider implementing configuration hardening practices, including disabling the use of Intel QAT with the affected ciphers until patches can be applied.
Regular monitoring and auditing of data transmission practices can help identify potential data leaks early. Organizations should review their security controls and ensure compliance with best practices.
For more information on security best practices, organizations can refer to the resources available at penetration testing.
Detection Guidance
Organizations should monitor for specific log indicators that might suggest unencrypted data transmissions. This includes tracking SSL handshake failures or anomalies in data traffic patterns.
Behavioral anomalies in network traffic should also be investigated thoroughly. Regular reviews of system configurations and network signatures can provide additional layers of detection.
