The login page on D-Link DIR-615 T1 20.10 devices allows remote attackers to bypass the CAPTCHA protection mechanism and conduct brute-force attacks.

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
Dir-615_firmware Dlink 20.10 (including) 20.10 (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]
