The Rattadan Cosmowarp smart contract before 56c6147 can have a comparison to an unintended value of current_admin.
AnalysisAI
Authorization bypass in the Rattadan Cosmowarp asset_registry smart contract (CosmWasm/Rust) lets any sender execute the privileged UpdateConfig message on deployments where the on-chain config.admin field is unset (None), because the sender-vs-admin check is nested inside an if let Some(current_admin) = config.admin block that is silently skipped. Impact is high on integrity and availability (VI:H/VA:H) with limited confidentiality loss (VC:L), scoring 8.4 under CVSS 4.0 and assessed as CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:H/A:H; exploitation is only possible against pre-56c6147 builds of the rattadan/Cosmowarp_Contract asset_registry module running with an unset admin, and no public exploit code or active exploitation (CISA KEV) has been identified at time of analysis. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the Cosmowarp asset_registry contract's config.admin field to be None (unset): the vulnerable execute_update_config only performs the `info.sender != current_admin` comparison inside an `if let Some(current_admin) = config.admin` block, so an unset admin causes the entire authorization check to be bypassed and any sender can execute UpdateConfig. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is an authorization-bypass flaw in a CosmWasm (Rust) smart contract, not a widely deployed enterprise product. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patch: update the asset_registry contract to commit 56c6147ee613a6aaa157ecefe2f7bf0ad9084fa8 or later (https://github.com/rattadan/Cosmowarp_Contract/commit/56c6147ee613a6aaa157ecefe2f7bf0ad9084fa8), which replaces the `if let Some(...)` guard with an explicit `ok_or(ContractError::Unauthorized)?` so that a missing admin is denied rather than implicitly allowed; because this is an on-chain smart contract, remediation means rebuilding and migrating each deployed instance, not patching a host. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all deployments of the rattadan/Cosmowarp_Contract asset_registry module and identify any running pre-56c6147 builds where the on-chain config.admin field is unset; for those, immediately set config.admin to a controlled address if operationally possible, pause or restrict update functions, and monitor for unauthorized UpdateConfig transactions. …
