Last modified
CVE-2024-41593 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. DrayTek Vigor310 devices through 4.3.2.6 allow a remote attacker to execute arbitrary code via the function ft_payload_dns(), because a byte sign-extension operation occurs for the length argument of a _memcpy call, leading to a heap-based Buffer Overflow.. EPSS estimates a 0.86% chance of exploitation in the next 30 days.
