radare2 Command Injection via DWARF Parameter Names

radare2 prior to commit bc5a890 contains a command injection vulnerability in the afsv/afsvj command path where crafted ELF binaries can embed malicious r2 command sequences as DWARF DW_TAG_formal_parameter names. Attackers can craft a binary with shell commands in DWARF parameter names that execute when radare2 analyzes the binary with aaa and subsequently runs afsvj, allowing arbitrary shell command execution through the unsanitized parameter interpolation in the pfq command string.

OS命令中使用的特殊元素转义处理不恰当(OS命令注入)

Radare2 安全漏洞

Radare2是Radare开源的一个面向 Unix 极客的 Libre 反向框架。 Radare2 bc5a890之前版本存在安全漏洞，该漏洞源于afsv/afsvj命令路径存在命令注入，特制ELF二进制文件可将恶意r2命令序列嵌入为DWARF DW_TAG_formal_parameter名称，可能导致执行任意shell命令。
