Description
The BPMN System REST APIs do not sufficiently validate input parameters, allowing authenticated users to submit crafted requests that can lead to the execution of arbitrary commands on the server.

An authenticated user can leverage this vulnerability to execute arbitrary commands with the privileges of the product's runtime account. The scope of potential damage is contingent upon the permissions assigned to this account.

AI Analysis

Impact

The vulnerability resides in the BPMN System REST APIs where input parameters are not adequately validated. An authenticated user can send crafted requests that cause the server to execute arbitrary commands. Because the commands run with the privileges of the product’s runtime account, the potential impact ranges from moderate to catastrophic depending on the permissions granted to that account.

Affected Systems

The affected products are WSO2 Business Process Server and the WSO2 Enterprise Integrator (BPS profile). No specific product versions are listed in the data; all supported releases remain potentially vulnerable until corrected.

Risk and Exploitability

The CVSS score of 8.8 indicates high severity. EPSS information is not available, and the issue is not listed in CISA KEV. Exploitation is possible only by users who have already authenticated to the REST interfaces, so the attack vector is likely local or internal. Once authenticated, an attacker can run commands that persist with the server’s runtime privileges.
