A heap-based buffer overflow vulnerability was discovered in rippled before version 1.8.5. The vulnerability allows attackers to cause a crash or execute commands remotely on a rippled node, which may lead to XRPL mainnet DoS or compromise. This exposes all digital assets on the XRPL to a security threat. The vulnerability was disclosed in April 2022 and received a CVSS v3.1 base score of 9.8 (CRITICAL) (NVD).

The vulnerability is classified as an out-of-bounds write (CWE-787) issue that affects rippled versions prior to 1.8.5.

This indicates that the vulnerability can be exploited remotely with no required privileges or user interaction, and can result in high impacts to confidentiality, integrity, and availability (NVD).

The vulnerability has severe potential impacts, including the ability for attackers to crash rippled nodes or execute arbitrary commands remotely. This could lead to denial of service on the XRPL mainnet or system compromise. The vulnerability puts all digital assets on the XRPL at security risk (NVD).
