Summary
A vulnerability was detected in radareorg radare2 in the r_core_cmd_str_pipe function of libr/core/rtr_http.inc.c, related to the HTTP sandbox policy handler. Manipulation results in a protection mechanism failure, and remote exploitation is possible though highly complex. The issue is fixed in version 6.2.4 (commit 18fd12efa98a7d1977de7bdd379d8a848777b90f).
Risk Assessment
With an exposed radare2 HTTP server, an attacker may bypass sandbox restrictions and run commands, including spawning processes. The risk mainly affects environments with a publicly reachable /cmd endpoint.
Recommendation
Upgrade radare2 to version 6.2.4 or later. Additionally, restrict network access to the radare2 HTTP server and do not expose the /cmd endpoint to untrusted users.
Other vulnerabilities in radare2
See all- CVE-2026-8696High
Version 6.1.5 of radare2 contains a use-after-free vulnerability in the gdbr_pids_list() function, which can be exploited by remote attackers to cause a denial of service or potentially execute arbitrary code by sending malformed thread information responses.
- CVE-2026-8695High
radare2 version 6.1.5 contains a use-after-free vulnerability in the gdbr_threads_list() function. This allows remote attackers to trigger memory corruption by sending a valid qfThreadInfo response followed by a malformed qsThreadInfo response.
- CVE-2017-15932High
In radare2 version 2.0.1, an integer exception (negative number leading to an invalid memory access) exists in store_versioninfo_gnu_verdef() in elf.c, which can be triggered by crafted ELF files when parsing the ELF version on 32-bit systems.
- CVE-2017-15931High
In radare2 version 2.0.1, an integer exception (negative number leading to an invalid memory access) exists in store_versioninfo_gnu_verneed() in elf.c, which can be exploited via crafted ELF files on 32-bit systems.
- CVE-2017-15385High
The store_versioninfo_gnu_verdef function in radare2 2.0.0 allows remote attackers to cause a denial of service via a crafted ELF file, leading to an invalid write in r_read_le16 and application crash.
- CVE-2017-15368High
The wasm_dis function in radare2 version 2.0.0 allows remote attackers to cause denial of service through stack-based buffer over-read, leading to application crash. The attack can be executed using a crafted WASM file that triggers an incorrect r_hex_bin2str call.
- CVE-2017-10929High
The grub_memmove function in radare2 1.5.0 allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) via a crafted binary file.
- CVE-2017-9949High
The grub_memmove function in radare2 1.5.0 allows remote attackers to cause a denial of service via a crafted binary file, potentially leading to application crashes due to a buffer underflow.
- CVE-2017-6448High
The dalvik_disassemble function in radare2 version 1.2.1 allows remote attackers to cause a denial of service (stack-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted DEX file.
- CVE-2017-6194High
The relocs function in libr/bin/p/bin_bflt.c in radare2 version 1.2.1 allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted binary file.
Original NVD description (English source)
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."
