IBM Spectrum Scale 5.0.0 through 5.0.5.5 and 5.1.0 through 5.1.0.2 uses an inadequate account lockout setting that could allow a local user er to brute force Rest API account credentials. IBM X-Force ID: 190974.

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
Spectrum_scale Ibm 5.0.0.0 (including) 5.0.5.5 (including)
Spectrum_scale Ibm 5.1.0.0 (including) 5.1.0.2 (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]
