CVE-2019-6963

Status: ModifiedHigh (8.8)—

A heap-based buffer overflow in cosa_dhcpv4_dml.c in the RDK RDKB-20181217-1 CcspPandM module may allow attackers with login credentials to achieve remote code execution by crafting a long buffer in the "Comment" field of an IP reservation form in the admin panel. This is related to the CcspCommonLibrary module.

CVSS
