CVE-2016-0382

Vulnerability

CVE-2016-0382 affects the IBM Tealeaf Consumer Experience portal versions 8.7, 8.8, and 9.0. The portal exposes some of its operational state in a form that may be accidentally captured and exposed by network infrastructure components such as IIS. This behavior is inherent to the portal's communication with intermediate devices and does not require any special configuration to be reachable [1].

Exploitation

An attacker must have local access to the network infrastructure (e.g., IIS logs, proxy caches, or other capture points) to observe the exposed operational state. The CVSS vector indicates a local attack with high complexity and no required privileges or user interaction (AV:L/AC:H/PR:N/UI:N). The exact sequence of steps may involve an attacker gaining access to logs or cached data where the portal's operational state was inadvertently stored by network components [1].

Impact

Successful exploitation leads to a low confidentiality impact — the attacker can obtain some operational state details of the Tealeaf portal. There is no impact on integrity or availability. The CVSS v3 base score is 4.0 (medium), and the CVSS temporal score from the reference lists a separate vector of 2.9 (low) [1]. The attacker gains information that could assist in further targeted attacks, but not direct system compromise.

Mitigation

IBM recommends updating to a fixed version of IBM Tealeaf Customer Experience; the security bulletin (swg22000590) provides guidance. For details on the specific fix version, consult the official IBM advisory [1]. As a workaround, network administrators should ensure that IIS and other infrastructure components are configured to not capture or retain the exposed operational state data, but the primary mitigation is to apply the vendor-supplied update.
