In Hyperledger Indy before version 1.12.4, there is lack of signature verification on a specific transaction which enables an attacker to make certain unauthorized alterations to the ledger. Updating a DID with a nym transaction will be written to the ledger if neither ROLE or VERKEY are being changed, regardless of sender. A malicious DID with no particular role can ask an update for another DID (but cannot modify its verkey or role). This is bad because 1) Any DID can write a nym transaction to the ledger (i.e., any DID can spam the ledger with nym transactions), 2) Any DID can change any other DID's alias, 3) The update transaction modifies the ledger metadata associated with a DID."}, {"lang": "es", "value": "Hyperledger Indy Node es la parte del servidor de un libro mayor distribuido dise\u00f1ado espec\u00edficamente para la identidad descentralizada. En Hyperledger Indy versiones anteriores a 1.12.4, se presenta una falta de verificaci\u00f3n de firma en una transacci\u00f3n espec\u00edfica que permite a un atacante hacer determinadas alteraciones no autorizadas en el libro mayor. La actualizaci\u00f3n de un DID con una transacci\u00f3n nym ser\u00e1 escrita en el libro mayor si ning\u00fan ROL ni CLAVE, han sido cambiados, independientemente del remitente. Un DID malicioso sin un rol en particular puede requerir una actualizaci\u00f3n para otro DID (pero no puede modificar su clave o rol). Esto es malo porque 1) Cualquier DID puede escribir una transacci\u00f3n nym en el libro mayor (es decir, cualquier DID puede enviar spam al libro mayor con transacciones nym), 2) Cualquier DID puede cambiar el alias de cualquier otro DID, 3) La transacci\u00f3n de actualizaci\u00f3n modifica los metadatos del libro mayor asociado con un DID"}], "lastModified": "2020-12-31T19:25:53.907", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:linuxfoundation:indy-node:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "28B5BA5E-162C-424C-A1D5-D9BA9D0FFD6E", "versionEndExcluding": "1.12.4"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
