Description

This security bulletin contains information about 10 secuirty vulnerabilities.


1) Improper authorization (CVE-ID: CVE-2017-12112)

The vulnerability allows a remote attacker to bypass authorization on the target system.

The weakness exists in admin_addPeer API of cpp-ethereum's JSON-RPC due to improper authorization. A remote attacker can make a specially crafted JSON request, gain access to the restricted functionality and bypass authorization.

2) Improper authorization (CVE-ID: CVE-2017-12113)

The vulnerability allows a remote attacker to bypass authorization on the target system.

The weakness exists in admin_nodeInfo API of cpp-ethereum's JSON-RPC due to improper authorization. A remote attacker can make a specially crafted JSON request, gain access to the restricted functionality and bypass authorization.

3) Improper authorization (CVE-ID: CVE-2017-12114)

The vulnerability allows a remote attacker to bypass authorization on the target system.

The weakness exists in admin_peers API of cpp-ethereum's JSON-RPC due to improper authorization. A remote attacker can make a specially crafted JSON request, gain access to the restricted functionality and bypass authorization.

4) Improper authorization (CVE-ID: CVE-2017-12115)

The vulnerability allows a remote attacker to bypass authorization on the target system.

The weakness exists in miner_setEtherbase API of cpp-ethereum's JSON-RPC due to improper authorization. A remote attacker can make a specially crafted JSON request, gain access to the restricted functionality and bypass authorization.

5) Improper authorization (CVE-ID: CVE-2017-12116)

The vulnerability allows a remote attacker to bypass authorization on the target system.

The weakness exists in miner_setGasPrice API of cpp-ethereum's JSON-RPC due to improper authorization. A remote attacker can make a specially crafted JSON request, gain access to the restricted functionality and bypass authorization.

6) Improper authorization (CVE-ID: CVE-2017-12117)

The vulnerability allows a remote attacker to bypass authorization on the target system.

The weakness exists in miner_start API of cpp-ethereum's JSON-RPC due to improper authorization. A remote attacker can make a specially crafted JSON request, gain access to the restricted functionality and bypass authorization.

7) Improper authorization (CVE-ID: CVE-2017-12118)

The vulnerability allows a remote attacker to bypass authorization on the target system.

The weakness exists in miner_stop API of cpp-ethereum's JSON-RPC due to improper authorization. A remote attacker can make a specially crafted JSON request, gain access to the restricted functionality and bypass authorization.

8) Denial of service (CVE-ID: CVE-2017-12119)

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists in multiple APIs of CPP-Ethereum's JSON-RPC due to an insufficient validation of user-supplied input. A remote attacker can make a specially crafted JSON request, trigger a unhandled exception and cause the application to crash.

9) Out-of-bounds read (CVE-ID: CVE-2017-14457)

The vulnerability allows a remote attacker to obtain potentially sensitive information or cause DoS condition on the target system.

The weakness exists due to an insufficient validation of user-supplied input. A remote attacker can create and send a specially crafted smart contract containing malicious code, trigger an out-of-bounds read and gain access to arbitrary data or cause the application to crash.

10) Privilege escalation (CVE-ID: CVE-2017-14460)

The vulnerability allows a remote attacker to gain elevated privileges on the target system.

The weakness exists due to an insufficient validation of user-supplied input. A remote attacker can send JSON object to JSON-RPC endpoint, trick the victim into visiting a specially crafted website, trigger overly permissive cross-domain (CORS) whitelist vulnerability in JSON-RPC and gain elevated privileges to perform further attacks.
