CVE-2026-23810: Medium Vulnerability in Aruba Networks ArubaOS

CVE-2026-23810 is a medium-severity vulnerability affecting Aruba Networks' ArubaOS, published on March 4, 2026. This vulnerability allows an authenticated attacker to craft and transmit a malicious Wi-Fi frame. The frame is classified as group-addressed traffic, which is then re-encrypted using the Group Temporal Key (GTK) associated with the victim's BSSID. Successful exploitation may enable GTK-independent traffic injection. When combined with a port-stealing technique, this vulnerability allows attackers to redirect intercepted traffic and facilitates machine-in-the-middle (MitM) attacks across BSSID boundaries.

The CVSS score for this vulnerability is 4.3, indicating a medium severity level. The attack vector is classified as adjacent network, and it requires no privileges or user interaction for exploitation. The low attack complexity further underscores the importance of addressing this vulnerability promptly. Organizations using affected versions of ArubaOS are at risk of unauthorized traffic redirection and potential data interception.

Given the nature of this vulnerability, organizations should prioritize remediation efforts. The potential for MitM attacks poses significant risks to sensitive data and network integrity. Immediate patching is critical to mitigate these risks and secure network environments.

As of now, there are no known exploits associated with CVE-2026-23810, but this should not diminish the urgency for patching. Organizations are advised to regularly monitor for updates and apply necessary patches as soon as they become available.

Vulnerability Details

This vulnerability is primarily linked to the packet processing logic within ArubaOS, which allows for potential exploitation through crafted Wi-Fi frames. The specific CVE description highlights the risk of GTK-independent traffic injection, which is critical in understanding the exploitation vector.

The CVSS 3.1 vector string for this vulnerability is CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N, indicating low attack complexity and no privileges required for exploitation. The confidentiality impact is low, while integrity and availability impacts are none.

Affected products include various versions of ArubaOS, specifically versions from 6.5.4.0 to 10.8.0.0. Organizations using these versions should ensure they are updated to the latest patches to mitigate this vulnerability.

Technical Analysis

The root cause of CVE-2026-23810 lies within the packet processing logic of ArubaOS, which incorrectly handles certain Wi-Fi frame classifications. This flaw allows attackers to exploit the frame classification process, leading to the re-encryption of malicious frames using a victim's GTK. The attack vector is categorized as adjacent network, meaning an attacker must be on the same network segment as the target.

With low attack complexity and no required privileges, this vulnerability is particularly dangerous, as it can be exploited by any authenticated user on the network. User interaction is not required, making it easier for attackers to launch their exploits. The impact on confidentiality is low, with no integrity or availability impacts.

Risk & Impact Analysis

Risk to organizations includes the potential for MitM attacks due to GTK-independent traffic injection. The ability to redirect intercepted traffic can lead to significant data breaches and unauthorized access to sensitive information. Organizations operating in environments where ArubaOS is deployed may face regulatory implications if sensitive data is compromised.

Given the CVSS score of 4.3 and the absence of known exploits, organizations should still treat the remediation of this vulnerability as a priority. The risk profile suggests that while immediate exploitation may not be widespread, the potential for future attacks remains. Therefore, organizations should address it in their patch cycle.

Affected Versions

Affected versions of ArubaOS include 6.5.4.0 to 10.8.0.0. Organizations should ensure they are using the latest version to mitigate the risk associated with this vulnerability.

Mitigation & Remediation

Organizations should prioritize applying the latest patches or updates provided by Aruba Networks. If a patch is not available, consider implementing workarounds such as network segmentation to limit exposure. Configuration hardening should also be applied to reduce the risk of potential exploitation.

For further assistance and security testing, organizations can utilize penetration testing services to validate their security posture.

Detection Guidance

Monitoring network logs for unusual Wi-Fi frame traffic can help detect potential exploitation attempts. Additionally, organizations should look out for behavioral anomalies in network traffic, particularly around group-addressed traffic.

AppSecure Threat Intelligence Insight
