Grandstream Networks UCM6510 v1.0.20.52 and before is vulnerable to Improper Restriction of Excessive Authentication Attempts. An attacker can perform an arbitrary number of authentication attempts using different passwords and eventually gain access to the targeted account using a brute force attack.

Weakness

The product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame, making it more susceptible to brute force attacks.

Affected Software

Name Vendor Start Version End Version
Ucm6510_firmware Grandstream * 1.0.20.52 (including)

Potential Mitigations

  • Common protection mechanisms include:

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.

  • Consider using libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator. [REF-45]
