CVE-2021-33571
HIGH7.5EPSS 0.01%Django Access Control Bypass possibly leading to SSRF, RFI, and LFI attacks
發布日:2021/6/10修改日:2025/4/3
描述
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+..) .
