Summary

An issue was discovered in SecurEnvoy SecurAccess 9.3.502. When put in Debug mode and used for RDP connections, the application stores the emergency credentials in cleartext in the logs (present in the DEBUG folder) that can be accessed by anyone. NOTE: The vendor disputes this as a vulnerability since the disclosure of a local account password (actually an alpha numeric passcode) is achievable only when a custom registry key is added to the windows registry. This action requires administrator access and the registry key is only provided by support staff at securenvoy to troubleshoot customer issues

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.
