CVE-2024-41338: n/a
A NULL pointer dereference in Draytek devices Vigor 165/166 prior to v4.2.6 , Vigor 2620/LTE200 prior to v3.9.8.8, Vigor 2860/2925 prior to v3.9.7, Vigor 2862/2926 prior to v3.9.9.4, Vigor 2133/2762/2832 prior to v3.9.8, Vigor 2135/2765/2766 prior to v4.4.5.1, Vigor 2865/2866/2927 prior to v4.4.5.3, Vigor 2962/3910 prior to v4.3.2.7, Vigor 3912 prior to v4.3.5.2, and Vigor 2925 up to v3.9.6 allows attackers to cause a Denial of Service (DoS) via a crafted DHCP request.
AI Analysis
Technical Summary
This vulnerability (CVE-2024-41338) is a NULL pointer dereference in several Draytek Vigor device models, including Vigor 165/166, 2620/LTE200, 2860/2925, 2862/2926, 2133/2762/2832, 2135/2765/2766, 2865/2866/2927, 2962/3910, and 3912. It occurs when processing a specially crafted DHCP request, causing the device to crash or become unresponsive, resulting in a Denial of Service. The affected versions are those prior to the listed firmware versions (e.g., prior to v4.2.6 for Vigor 165/166). The CVSS v3.1 base score is 7.5, indicating high severity, with network attack vector, low attack complexity, no privileges required, no user interaction, and impact limited to availability. There is no vendor advisory or patch information provided, and no known exploitation in the wild has been reported.
Potential Impact
Successful exploitation causes a Denial of Service by crashing or destabilizing the affected Draytek devices, disrupting network availability. There is no impact on confidentiality or integrity reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider limiting exposure of affected devices to untrusted networks to reduce risk from crafted DHCP requests.
