Summary

All versions of com.gradle.plugin-publish before 0.11.0 are vulnerable to Insertion of Sensitive Information into Log File. When a plugin author publishes a Gradle plugin while running Gradle with the --info log level flag, the Gradle Logger logs an AWS pre-signed URL. If this build log is publicly visible (as it is in many popular public CI systems like TravisCI) this AWS pre-signed URL would allow a malicious actor to replace a recently uploaded plugin with their own.

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.
