Summary

Apache Geode versions up to 1.12.4 and 1.13.4 are vulnerable to a log file redaction of sensitive information flaw when using values that begin with characters other than letters or numbers for passwords and security properties with the prefix "sysprop-", "javax.net.ssl", or "security-". This issue is fixed by overhauling the log file redaction in Apache Geode versions 1.12.5, 1.13.5, and 1.14.0.

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.
