| 제목 | antlr ANTLR4 4.13.2 Code Injection |
|---|
| 설명 | ANTLR4 grammar files (.g4) support embedded action blocks — @header { }, @members { }, @init { }, @after { }, and inline { } actions — that are injected verbatim and without sanitization into the generated source code. Any system that accepts .g4 files from untrusted sources and compiles/executes the generated output is fully compromised. The attack requires no special privileges; a single .g4 file causes Remote Code Execution upon class loading. |
