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."

Impact

A vulnerability was discovered in radareorg radare2 6.2.0 and 6.2.2 within the HTTP Sandbox Policy Handler. The flaw lies in the function r_core_cmd_str_pipe, which fails to enforce the sandbox while the HTTP server is running. The misconfiguration allows commands sent to the /cmd endpoint to spawn processes because cfg.sandbox.grain defaults to allow all capabilities, including exec. This security misconfiguration (CWE‑693) can enable an attacker who can reach the HTTP interface to execute arbitrary code on the host.

Affected Systems

The affected product is radareorg radare2, specifically versions 6.2.0 and 6.2.2. A fix is available in radare2 6.2.4, which corrects the sandbox handling for HTTP commands. The issue does not affect older major releases shown by the CPE listing but is limited to the 6.x series given.

Risk and Exploitability

The CVSS base score of 6.3 indicates moderate severity, and the analysis labels the attack complexity as high and exploitation difficulty as hard. EPSS is currently not available, but the possibility of remote exploitation exists only when the HTTP server is exposed to untrusted users. The vulnerability is not listed in the CISA KEV catalog, meaning no confirmed exploitation has been reported yet. Nonetheless, the risk is non‑negligible for deployments that run the vulnerable radare2 instance behind unfiltered network exposure.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade radare2 to version 6.2.4 or later, which patches the sandbox handling in the HTTP component.
  • If the HTTP server is not needed, disable or remove the http server and command endpoint to eliminate the attack surface.
  • If the HTTP server must be used, configure the sandbox to restrict exec privileges by setting cfg.sandbox.grain appropriately or by disabling unused sandbox capabilities.
