A vulnerability in the audit logging component of Cisco Unified Communications Manager, Cisco Unified Communications Manager Session Management Edition, Cisco Unified Communications Manager IM & Presence Service, Cisco Unity Connection, Cisco Emergency Responder, and Cisco Prime License Manager could allow…

more

an authenticated, remote attacker to view sensitive information in clear text on an affected system. The vulnerability is due to the storage of certain unencrypted credentials. An attacker could exploit this vulnerability by accessing the audit logs on an affected system and obtaining credentials that they may not normally have access to. A successful exploit could allow the attacker to use those credentials to discover and manage network devices.

addresses: CWE-532

Procedures mandate excluding sensitive data from logs to prevent unauthorized exposure via audit records.

addresses: CWE-532

Identifies insertion of sensitive data into logs, allowing detection of unauthorized disclosure.

addresses: CWE-532

Cross-organizational coordination enables agreement on what data to include in audit logs, directly reducing insertion of sensitive information.

addresses: CWE-532

Identifying logging as a data action allows prevention of sensitive information being inserted into log files.

addresses: CWE-532

The process of identifying and eradicating spilled information applies directly to sensitive data inserted into log files.

addresses: CWE-532

Specific processing rules for sensitive PII categories commonly include restrictions on logging, making insertion of such data into log files less likely.

addresses: CWE-532

PIAs detect planned or existing logging of PII and require removal or protection, preventing insertion of sensitive information into logs.

addresses: CWE-532

Limits insertion of sensitive operational details into logs by treating such data as key information requiring protection.
