What MITRE CAPEC-267: Leverage Alternate Encoding (Standard Attack Pattern - High Severity) requires
MITRE CAPEC-267 (Leverage Alternate Encoding) is a standard-level attack pattern in the MITRE Common Attack Pattern Enumeration and Classification. An adversary leverages the possibility to encode potentially harmful input or content used by applications such that the applications are ineffective at validating this encoding standard. Likelihood of attack: High. Typical severity: High. Parent pattern for CAPEC-120 Double Encoding; CAPEC-3 Using Leading 'Ghost' Character Sequences to Bypass Input Filters; CAPEC-4 Using Alternative IP Address Encodings; and others. Maps to weaknesses CWE-173, CWE-172, CWE-180, CWE-181, and others. Relates to MITRE ATT&CK T1027.
