CVE-2018-3621

Vulnerability

The Intel Driver & Support Assistant (DSA) prior to version 3.6.0.4 contains an input validation flaw that can lead to information disclosure [1]. The vulnerability stems from the software's failure to properly sanitize or validate input data, opening a path for data exposure to an adjacent attacker [1].

Exploitation

An attacker must be on the same adjacent network segment as the targeted system. No authentication is required to exploit the issue, and the attacker can deliver crafted input to the vulnerable DSA component, forcing it to disclose sensitive information [1].

Impact

Successful exploitation results in the disclosure of information. The attacker gains no write or execute privileges; the impact is limited to unauthorized reading of data accessible to the DSA process, which could include system configuration or user-related details [1].

Mitigation

Intel released DSA version 3.6.0.4 to address CVE-2018-3621 [1]. Users should update to this version or later. No workaround is described in the available reference [1]. This CVE is not listed on the CISA Known Exploited Vulnerabilities (KEV) catalog as of the publication date.
