CVE-2021-29853

Vulnerability

The vulnerability exists in IBM Planning Analytics 2.0 (specifically in the Planning Analytics Workspace component) where the software fails to validate return values from certain methods or functions. This oversight can lead to information exposure. The affected versions are those prior to Planning Analytics Local v2.0 - Planning Analytics Workspace Release 67 [1]. The issue is tracked as CVE-2021-29853 and is distinct from other vulnerabilities in the same advisory.

Exploitation

An attacker with low-privileged network access can exploit this vulnerability. The attack vector is network-based, requires low complexity, and does not require user interaction. The attacker does not need any special privileges beyond network access to the affected system. By triggering the vulnerable code paths that do not validate return values, an attacker can obtain information that may be used to craft further attacks [1].

Impact

Successful exploitation leads to a limited information disclosure (confidentiality impact: low). The attacker gains no access to modify data or disrupt services directly, but the exposed information can aid in constructing subsequent attacks. The CVSS base score is 4.3, indicating a moderate severity [1].

Mitigation

IBM has released the fix in Planning Analytics Local v2.0 - Planning Analytics Workspace Release 67. Users should upgrade to this version or later to remediate the vulnerability. No workarounds are described in the available references [1].
