Detailsinfo

A vulnerability has been found in iot-ecology rust-iot-platform (the affected version unknown) and classified as critical. Affected by this vulnerability is the function quick_js::Context::eval of the file api/src/biz/calc_run_biz.rs of the component Calc Rule. The manipulation of the argument script with an unknown input leads to a code injection vulnerability. The CWE definition for the vulnerability is CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

rust-iot-platform allows creating a "calc rule" via POST /calc-rule/create (api/src/controller/calc_rule_router.rs) containing an arbitrary `script` field. This route does not take the AuthToken request guard used elsewhere in the application, making it reachable without authentication. The stored script is subsequently executed via quick_js::Context::eval() in api/src/biz/calc_run_biz.rs with no sandboxing, allowing an unauthenticated attacker to achieve arbitrary JavaScript execution in the server process by creating and triggering a malicious calc rule.

The advisory is shared at github.com. This vulnerability is known as CVE-2026-71278 since 08/05/2026. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details are known, but no exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 08/05/2026). MITRE ATT&CK project uses the attack technique T1059 for this issue.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
