An incorrect parsing of numbers with different radices vulnerability [CWE-1389] in FortiProxy version 7.4.3 and below, version 7.2.10 and below, version 7.0.17 and below and FortiOS version 7.4.3 and below, version 7.2.8 and below, version 7.0.15 and below IP address validation feature may permit an unauthenticated attacker to bypass the IP blocklist via crafted requests.
Solution:
The product parses numeric input assuming base 10 (decimal) values, but it does not account for inputs that use a different base number (radix).
The product does not correctly convert an object, resource, or structure from one type to a different type.
