CVE-2020-29069 (GCVE-0-2020-29069)

Vulnerability from cvelistv5 – Published: 2020-11-24 23:32 – Updated: 2024-08-04 16:48

Summary

_get_flag_ip_localdb in server/mhn/ui/utils.py in Modern Honey Network (MHN) through 2020-11-23 allows attackers to cause a denial-of-service via an IP address that is absent from a local geolocation database, because the code tries to uppercase a return value even if that value is not a string.
