Kerentanan Out-of-bounds Read pada hcc-embedded nichestack, siemens 7km9300-0ae02-0aa0 firmware. Skor CVSS 3.1 7.5 (High) menurut NVD.

Deskripsi (NVD)

An issue was discovered in HCC Nichestack 3.0. The code that parses ICMP packets relies on an unchecked value of the IP payload size (extracted from the IP header) to compute the ICMP checksum. When the IP payload size is set to be smaller than the size of the IP header, the ICMP checksum computation function may read out of bounds, causing a Denial-of-Service.
