CVE-2020-9409

The administrative UI component of TIBCO Software Inc.s TIBCO JasperReports Server, TIBCO JasperReports Server for AWS Marketplace, and TIBCO JasperReports Server for ActiveMatrix BPM contains a vulnerability that theoretically allows an unauthenticated attacker to obtain the permissions of a JasperReports Server superuser for the affected systems. The attacker can theoretically exploit the vulnerability consistently, remotely, and without authenticating. Affected releases are TIBCO Software Inc.s TIBCO JasperReports Server: versions 7.1.1 and below, TIBCO JasperReports Server for AWS Marketplace: versions 7.1.1 and below, and TIBCO JasperReports Server for ActiveMatrix BPM: versions 7.1.1 and below.

Weakness

During installation, installed file permissions are set to allow anyone to modify those files.

Affected Software

Potential Mitigations

• Compartmentalize the system to have “safe” areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
• Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
