CVE-2026-40517— radare2 < 6.1.4 Command Injection via PDB Parser Symbol Names

radare2 < 6.1.4 Command Injection via PDB Parser Symbol Names

radare2 prior to 6.1.4 contains a command injection vulnerability in the PDB parser's print_gvars() function that allows attackers to execute arbitrary commands by crafting a malicious PDB file with newline characters in symbol names. Attackers can inject arbitrary radare2 commands through unsanitized symbol name interpolation in the flag rename command, which are then executed when a user runs the idp command against the malicious PDB file, enabling arbitrary OS command execution through radare2's shell execution operator.

CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H

OS命令中使用的特殊元素转义处理不恰当(OS命令注入)

Radare2 操作系统命令注入漏洞

Radare2是Radare开源的一个面向 Unix 极客的 Libre 反向框架。 Radare2 6.1.4之前版本存在操作系统命令注入漏洞，该漏洞源于PDB解析器的print_gvars函数存在命令注入，可能导致攻击者通过制作包含换行符的恶意PDB文件，在用户对恶意文件运行idp命令时执行任意操作系统命令。
