CVE-2023-2646

Service interruption via crafted GET parameters

Published May 11, 2023 · Updated Jan 24, 2025

Denial of service in TP-Link Archer C7v2 v2_en_us_180114 allows attackers on the local network to interrupt router service. The published record identifies the GET request parameter handler as the locus but does not disclose the endpoint, parameter, or incorrect resource-release operation. Network adjacency is required, and successful exploitation affects availability; public details do not establish whether recovery is automatic or requires a reboot.
