indy-node is the server portion of Hyperledger Indy, a distributed ledger purpose-built for decentralized identity. In vulnerable versions of indy-node, an attacker can max out the number of client connections allowed by the ledger, leaving the ledger unable to be used for its intended purpose. However, the ledger content will not be impacted and the ledger will resume functioning after the attack. This attack exploits the trade-off between resilience and …
The pool-upgrade request handler in Indy-Node <=1.12.4 allows an improperly authenticated attacker to remotely execute code on nodes within the network. Network operators are strongly encouraged to upgrade to the latest Indy-Node release >=1.12.5 as soon as possible.
Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in indy-node.
Hyperledger Indy Node is the server portion of a distributed ledger purpose-built for decentralized identity. In Hyperledger Indy, there is lack of signature verification on a specific transaction which enables an attacker to make certain unauthorized alterations to the ledger.
Indy Node has a bug in TAA handling code. The current primary can be crashed with a malformed transaction from a client, which leads to a view change. Repeated rapid view changes have the potential of bringing down the network.
