Because the endpoint lacks @SaveAction, attackers can save arbitrary codec providers and configurations, controlling how transparent messages are decoded and encoded for every device of that product.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","cwes":["CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://github.com/hs-web/hsweb-framework/blob/5.0.1/hsweb-authorization/hsweb-authorization-api/src/main/java/org/hswebframework/web/authorization/Authentication.java#L206-L218","tags":[]},{"url":"https://github.com/jetlinks/jetlinks-community","tags":[]},{"url":"https://github.com/jetlinks/jetlinks-community/blob/60ecc9f65d96acfd38da8daecdb0062fc72034f3/jetlinks-manager/device-manager/src/main/java/org/jetlinks/community/device/web/TransparentMessageCodecController.java#L138-L143","tags":[]},{"url":"https://hackmd.io/@1ExmmukzRMWN7B4gQ4W-4Q/jetlinks-community-transparent-codec-save-authz-bypass","tags":[]},{"url":"https://www.vulncheck.com/advisories/jetlinks-community-through-2.10.0-missing-authorization-via-product-level-transparent-codec-save","tags":[]}],"exploitRefs":[{"url":"https://github.com/hs-web/hsweb-framework/blob/5.0.1/hsweb-authorization/hsweb-authorization-api/src/main/java/org/hswebframework/web/authorization/Authentication.java#L206-L218","tags":[]},{"url":"https://github.com/jetlinks/jetlinks-community","tags":[]},{"url":"https://github.com/jetlinks/jetlinks-community/blob/60ecc9f65d96acfd38da8daecdb0062fc72034f3/jetlinks-manager/device-manager/src/main/java/org/jetlinks/community/device/web/TransparentMessageCodecController.java#L138-L143","tags":[]}],"hasPoc":true,"ai":null}
