CVE-2024-51427 identifies a critical vulnerability in the PepeGxng smart contract deployed on the Ethereum blockchain. The issue lies within the mint function, which can be invoked remotely by attackers without any authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The vulnerability is classified under CWE-94, which typically relates to code injection or unsafe execution of code, suggesting that the mint function may allow attackers to execute arbitrary or unauthorized code paths. This can lead to unauthorized creation (minting) of tokens, severely impacting the contract's integrity and the overall token economy. Although some third parties dispute the severity, the official CVSS score of 9.8 reflects critical impact on confidentiality, integrity, and availability. The vulnerability affects all versions of the PepeGxng contract, but no specific patched versions are listed yet. No known exploits have been observed in the wild, but the potential for exploitation is high given the lack of required privileges and user interaction. The exploitability is straightforward due to the open nature of the Ethereum blockchain and the public accessibility of smart contract functions. This vulnerability could enable attackers to inflate token supply, manipulate token balances, or disrupt the contract’s normal operations, leading to financial losses and reputational damage for users and organizations relying on this contract.

The impact of CVE-2024-51427 is significant for organizations and individuals using the PepeGxng smart contract or related decentralized applications (dApps). Unauthorized minting can lead to inflation of tokens, devaluation of assets, and loss of user funds. This undermines trust in the affected blockchain ecosystem and can cause cascading effects on exchanges, wallets, and other services that integrate with the contract. Financial institutions, DeFi platforms, and investors relying on the PepeGxng token could face direct monetary losses. The integrity of the blockchain ledger is compromised, potentially affecting transaction validity and user balances. Additionally, the availability of the contract’s services could be disrupted if attackers exploit the vulnerability to overload or destabilize the contract. Given the critical severity and ease of exploitation, the threat poses a high risk to the broader Ethereum community and any stakeholders involved with this token.

To mitigate CVE-2024-51427, organizations should immediately audit the PepeGxng smart contract code, focusing on the mint function to identify and eliminate unsafe code execution paths. Access controls must be enforced to restrict mint function calls to authorized entities only, such as implementing role-based permissions or multisignature requirements. Deploy updated contract versions with hardened security measures, including input validation, proper authorization checks, and use of established secure coding patterns for smart contracts. Consider using formal verification tools to prove the absence of code injection vulnerabilities. Monitor blockchain activity for unusual minting transactions and set up alerting mechanisms. Users and platforms should avoid interacting with the vulnerable contract until a secure patch is released. Additionally, educating developers on secure smart contract design and conducting regular security assessments can prevent similar vulnerabilities in future deployments.
