Blockchain security Halborn says a vulnerability it found last year on the open-source codebase of the Dogecoin network is still present in at least 280 other networks, as per a Monday post. During an assessment in 2022, the researchers found several critical vulnerabilities that could have been exploited by attackers to compromise the network. At the time, Dogecoin developers addressed and resolved the vulnerabilities. However, further investigations by Halborn revealed that similar vulnerabilities were present in several other networks, including Litecoin and Zcash. This could potentially expose over $25 billion worth of tokens to potential security risks, Halborn said. “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 CEO Rob Behnke said. “On vulnerable networks a successful exploitation of the relevant vulnerability could lead to denial of service or remote code execution.” Halborn has dubbed the vulnerability “Rab13s.” According to the researchers, the most critical vulnerability found in the affected networks pertains specifically to the way peer-to-peer (p2p) communications are conducted in these networks. An attacker can send malicious consensus messages to individual nodes in the network, causing them to shut down and leaving the entire network vulnerable to 51% attacks or other severe issues.
