CVE-2024-39805 is a vulnerability identified in Intel(R) Dynamic System Analysis (DSA) software versions before 23.4.39. The root cause is insufficient verification of data authenticity within the software, which can be exploited by an authenticated local user to escalate privileges on the affected system. This means that a user with limited privileges who already has local access can potentially gain higher-level privileges, compromising system security. The vulnerability does not require user interaction beyond authentication but has a high attack complexity, indicating that exploitation is non-trivial and may require specific conditions or expertise. The CVSS 4.0 base score is 7.3, reflecting a high severity level, with vector metrics indicating local attack vector (AV:L), high attack complexity (AC:H), privileges required (PR:L), and no user interaction (UI:N). The impact metrics show high confidentiality, integrity, and availability impacts (C:H, I:H, A:H). No known exploits have been reported in the wild so far. Intel has reserved the CVE and published the vulnerability details, but no direct patch links were provided in the source information. The vulnerability affects environments where Intel DSA software is deployed, which typically includes enterprise and data center systems leveraging Intel hardware for system analysis and management.

The vulnerability allows an authenticated local user to escalate privileges, potentially gaining administrative or root-level access. This can lead to full system compromise, unauthorized access to sensitive data, modification or deletion of critical system files, and disruption of system availability. Organizations relying on Intel DSA software for system monitoring or management could see their security posture severely weakened if this vulnerability is exploited. The high impact on confidentiality, integrity, and availability means that attackers could manipulate system operations, exfiltrate data, or cause denial of service. Although exploitation requires local access and is complex, insider threats or attackers who have already compromised low-level accounts could leverage this vulnerability to deepen their control. This elevates the risk in environments with multiple users or where local access controls are weak. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, especially as details become public and attackers develop exploits.

1. Upgrade Intel DSA software to version 23.4.39 or later as soon as possible to apply the fix addressing this vulnerability. 2. Enforce strict local access controls and limit the number of users with local authenticated access to systems running Intel DSA software. 3. Implement robust monitoring and logging of local user activities to detect unusual privilege escalation attempts or unauthorized access patterns. 4. Use endpoint protection solutions capable of detecting privilege escalation behaviors. 5. Conduct regular audits of user permissions and remove unnecessary local accounts or privileges. 6. Employ multi-factor authentication (MFA) for local logins where supported to reduce risk of credential compromise. 7. Isolate critical systems running Intel DSA software within secure network segments to limit lateral movement opportunities. 8. Educate system administrators and users about the risks of privilege escalation vulnerabilities and the importance of applying patches promptly. 9. Develop and test incident response plans specifically addressing local privilege escalation scenarios to ensure rapid containment if exploited.
