CVE-2023-22791 Explained : Impact and Mitigation

This CVE involves a vulnerability in Aruba Access Points running InstantOS and ArubaOS 10, impacting certain versions of the software. The issue could potentially lead to the disclosure of sensitive information through the WLAN under specific conditions.

Understanding CVE-2023-22791

This vulnerability in Aruba InstantOS and ArubaOS 10 highlights a scenario where a combination of network settings, a particular WLAN environment, and an attacker with valid user credentials on the WLAN could result in the exposure of sensitive data through the WLAN. The complexity of the scenarios leading to this potential data disclosure is influenced by various factors beyond the attacker's control.

What is CVE-2023-22791?

The vulnerability identified in Aruba InstantOS and ArubaOS 10 allows for the disclosure of sensitive information through the WLAN when certain network configurations align with a specific WLAN environment and an attacker holds valid user credentials on the network. The disclosure of sensitive data can occur in complex scenarios determined by factors outside the attacker's influence.

The Impact of CVE-2023-22791

This vulnerability has a CVSSv3.1 base score of 5.4, categorizing it as a medium severity issue. With a high confidentiality impact and low integrity impact, the vulnerability requires low privileges to exploit. The attack complexity is high, and the attack vector is through the adjacent network. While the availability impact is none, the disclosure of high-confidentiality information poses a significant risk.
