CVE-2023-2900Public exploitNetwork attack vector

Administrator access via reusable password hash

Published May 25, 2023 · Updated Aug 2, 2024

Weak password handling in NFine Rapid Development Platform 20230511 allows remote attackers to access an administrator account. The CheckLogin endpoint treats a reusable MD5 digest as the credential, and the published request logs in as admin with the digest for 0000. No prior authentication is required, but exploitation has high complexity; success grants the account's application access, while published CVSS impact is limited to data disclosure.
