Summary
A high-severity integrity bypass vulnerability existed in Striae's digital confirmation workflow prior to v3.0.0. Hash-only validation trusted manifest hash fields that could be modified together with package content, allowing tampered confirmation packages to pass integrity checks.
Impact
Confirmation package integrity could be bypassed because both content and hash values were mutable in the same trust boundary. An attacker with access to an exported package could alter confirmation data and recompute hashes so hash-only checks still passed.
This affects users relying on digital confirmations as an immutability and forensic chain-of-custody control.
Patches
Patched in v3.0.0.
Upgrade to:
v3.0.0or later
Security behavior added in v3.0.0:
- Server-issued asymmetric signatures for forensic manifests
- Canonical payload signature verification during import and manual hash verification
- Fail-closed behavior when signature metadata is missing or invalid
- Signature/key provenance support for audit-related workflows
Workarounds
There is no full cryptographic workaround equivalent to upgrading.
Temporary mitigations:
- Treat hash-only validation as a tamper indicator, not proof of immutability
- Restrict package exchange to trusted authenticated internal channels
- Require out-of-band reviewer attestation for sensitive confirmation workflows
- Pause imports from untrusted sources until upgraded
The vulnerability requires local access to the device to be exploited. It is easy for an attacker to exploit this vulnerability. An attacker does not need any special privileges or access rights. The attacker needs the user to perform some action, like clicking a link. The vulnerability can affect other systems as well, not just the initial system. There is a high impact on the confidentiality of the information. There is a high impact on the integrity of the data.
Exploitation activity has been observed. Apply available patches or mitigations urgently.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
