A zero-day exploit first discovered on Dogecoin could affect more than 280 other blockchain networks, according to cybersecurity firm Halborn.
Other zero-day vulnerabilities it found would allow potential attackers to crashby sending Remote Procedure Call requests — a protocol allowing a program to communicate and request services from another.
7/ Secondly, attackers can execute code through the public interface as a normal node user. Since a valid credential is required to carry out the attack, the likelihood of this exploit is lower.It added the likelihood of RPC-related exploits was lower as it requires valid credentials to undertake the attack.
“Due to codebase differences between the networks not all the vulnerabilities are exploitable on all the networks, but at least one of them may be exploitable on each network,” Halborn warned.The firm said at this time it’s not releasing further technical details of the exploits due to their severity and added it made a “good faith effort” to contact all affected parties to disclose the potential exploits and provide remediation for the vulnerabilities.
Dogecoin, Zcash and Litecoin have already implemented patches for the discovered vulnerabilities, but hundreds could still be exposed according to Halborn.
