Описание
In Django 2.2 before 2.2.24, 3.x before 3.1.12, and 3.2 before 3.2.4, URLValidator, validate_ipv4_address, and validate_ipv46_address do not prohibit leading zero characters in octal literals. This may allow a bypass of access control that is based on IP addresses. (validate_ipv4_address and validate_ipv46_address are unaffected with Python 3.9.5+..) .
A flaw was found in django. Leading zeros in octal literals aren't prohibited in IP addresses. If you used such values you could suffer from indeterminate SSRF, RFI, and LFI attacks. The highest threat from this vulnerability is to data integrity.
Отчет
Red Hat Update Infrastructure is in maintenance phase and we will not be fixing Medium/Low impact security bugs. Reference: https://access.redhat.com/support/policy/updates/rhui In Red Hat OpenStack Platform 13, because the flaw has a lower impact and the fix would require a substantial amount of development, no update will be provided at this time for the RHOSP python-django package.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
