一分钟漏洞结论
影响对象
radareorg radare2
利用判断
尚无明确在野利用证据，仍需结合暴露面评估
建议动作
优先检查厂商安全公告和参考链接中的修复版本；无法立即升级时，限制受影响服务暴露并加强监测。
在 radare2 6.2.0 和 6.2.2 版本中检测到一个安全漏洞。该问题影响 libr/core/rtr_http.inc.c 库中 HTTP 沙箱策略处理器组件的 r_core_cmd_str_pipe 函数。攻击者通过操纵该函数可导致防护机制失效，且该漏洞可被远程利用。攻击复杂度较高，利用难度被评估为“困难”。升级至 6.2.4 版本可修复此问题，相关补丁提交哈希为 18fd12efa98a7d1977de7bdd379d8a848777b90f。建议尽快升级受影响组件。该漏洞的利用前提已体现在 CVS

Vulnerability Title
radareorg radare2 HTTP Sandbox Policy rtr_http.inc.c r_core_cmd_str_pipe protection mechanism
来源: CVE Program / CVE List V5
Vulnerability Description
A vulnerability was detected in radareorg radare2 6.2.0/6.2.2. This issue affects the function r_core_cmd_str_pipe in the library libr/core/rtr_http.inc.c of the component HTTP Sandbox Policy Handler. Performing a manipulation results in protection mechanism failure. Remote exploitation of the attack is possible. The attack is considered to have high complexity. The exploitability is assessed as difficult. Upgrading to version 6.2.4 is capable of addressing this issue. The patch is named 18fd12efa98a7d1977de7bdd379d8a848777b90f. Upgrading the affected component is recommended. The pre-requisite of the vulnerability is reflected by the CVSS vector. One of the project maintainers explains: "There is a real sandbox configuration issue here, but the report overstates it. The HTTP server defaults to http.sandbox=true, so commands received through /cmd temporarily enable cfg.sandbox. However, cfg.sandbox.grain defaults to all, which means all sandbox capabilities - including exec - remain allowed. Therefore enabling the HTTP sandbox alone does NOT prevent commands from spawning processes. This only matters when the HTTP command endpoint is reachable by someone you do not trust. It is not a remote vulnerability by default: the HTTP server must first be started and exposed to the attacker."
