Security Bulletin: IBM Cúram Social Program Management when not configured with LDAP or SSO may be vulnerable to denial of service.(CVE-2014-6092).

Security Bulletin


Default authentication methods in IBM Curam Social Program Management do not allow for a per user account lockout policy, and rather employ a single, system wide policy. For most users of the system, a low lockout threshold is desirable. However, for users used to integrate with another system, such as a user whose sole purpose is to allow another system to invoke a particular web service, a low threshold for lockout may allow an attacker to lock out the other system, thereby effecting a denial of service. This is context specific and default authentication in Curam does not allow for appropriate levels of configuration on the lockout threshold.

Default authentication in IBM Curam Social Program Management now supports additional configuration to allow more flexibility in this configuration. See the release notes of the relevant release for the supported options for configuration of password lockout policy.

Customers of IBM Curam Social Program Management using an alternative authentication system such as LDAP are NOT affected.

Vulnerability Details

Workarounds and Mitigations

(i) It is possible to increase the number of login retries but enforce a stronger password policy. The password must be strong enough to resist brute-force/dictionary attacks, reducing the importance of the account lockout policy.

(ii) The period time that an account is locked can also be modified. Rather than permanently lock down accounts which enables attackers to execute permanent DoS attacks on legitimate clients, temporarily locking down accounts only allows for temporary DoS attacks.

If employing either of these mitigation strategies, authentication failures should be monitored closely.
