CVE-2023-31098Network attack vector

Account compromise via one-character password acceptance

Published May 22, 2023 · Updated Oct 11, 2024

Weak password requirements in Apache InLong 1.1.0 through 1.6.0 allow remote attackers to access accounts by guessing simple passwords. UserRequest validates both password and newPassword at only one to 64 characters, so a one-character password passes the manager input constraint. Exploitation requires an account whose user selected such a short password; successful guessing grants only that account's assigned privileges.
