CWE-532

Summary

A vulnerability in a logging function of Cisco Nexus Dashboard Insights could allow an attacker with access to a tech support file to view sensitive information. This vulnerability exists because remote controller credentials are recorded in an internal log that is stored in the tech support file. An attacker could exploit this vulnerability by accessing a tech support file that is generated from an affected system. A successful exploit could allow the attacker to view remote controller admin credentials in clear text. Note: Best practice is to store debug logs and tech support files safely and to share them only with trusted parties because they may contain sensitive information.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Fuzzing and observing application log data/errors for application mapping
    An attacker sends random, malformed, or otherwise unexpected messages to a target application and observes the application's log or error messages returned. Fuzzing techniques involve sending random or malformed messages to a target and monitoring the target's response. The attacker does not initially know how a target will respond to individual messages but by attempting a large number of message variants they may find a variant that trigger's desired behavior. In this attack, the purpose of the fuzzing is to observe the application's log and error messages, although fuzzing a target can also sometimes cause the target to enter an unstable state, causing a crash. By observing logs and error messages, the attacker can learn details about the configuration of the target application and might be able to cause the target to disclose sensitive information.
