Summary

Laf is a cloud development platform. In the Laf version design, the log uses communication with k8s to quickly retrieve logs from the container without the need for additional storage. However, in version 1.0.0-beta.13 and prior, this interface does not verify the permissions of the pod, which allows authenticated users to obtain any pod logs under the same namespace through this method, thereby obtaining sensitive information printed in the logs. As of time of publication, no known patched versions exist.

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.
