Kerentanan Improper Validation of Specified Type of Input. Skor CVSS 3.1 7.5 (High) menurut CISA ADP.

Deskripsi (NVD)

Net::IP::LPM versions before 1.12 for Perl accept malformed prefix lengths. Non-numeric and non-ASCII prefix lengths are accepted and treated as 0. Integers over 31 bits are silently truncated. A single malformed mask will poison the lookup table. The result is that the lookup will silently succeed for every address. An allow-list will allow every address, and a deny-list will block every address.
