CVE-2025-56224: n/a
A lack of rate limiting in the One-Time Password (OTP) verification endpoint of SigningHub v8.6.8 allows attackers to bypass verification via a bruteforce attack.
AI Analysis
Technical Summary
CVE-2025-56224 describes a vulnerability in SigningHub v8.6.8 where the OTP verification endpoint does not implement rate limiting. This absence enables attackers to attempt multiple OTP guesses without restriction, potentially bypassing the verification mechanism. The vulnerability is identified as CWE-307 (Improper Restriction of Excessive Authentication Attempts). The CVSS 3.1 base score is 8.1, reflecting network attack vector, high attack complexity, no privileges or user interaction required, and high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows an attacker to bypass OTP verification via brute force, potentially compromising user accounts and sensitive operations protected by OTP. This could lead to unauthorized access, data exposure, and disruption of service.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider implementing external rate limiting or monitoring on the OTP endpoint to detect and block brute force attempts.
