A missing rate limit in the Preferred Providers app 1.7.0 allowed an attacker to set the password an uncontrolled amount of times.

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
Preferred_providers Nextcloud 1.7.0 (including) 1.7.0 (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]
