Summary

ydb-go-sdk is a pure Go native and database/sql driver for the YDB platform. Since ydb-go-sdk v3.48.6 if you use a custom credentials object (implementation of interface Credentials it may leak into logs. This happens because this object could be serialized into an error message using `fmt.Errorf("something went wrong (credentials: %q)", credentials)` during connection to the YDB server. If such logging occurred, a malicious user with access to logs could read sensitive information (i.e. credentials) information and use it to get access to the database. ydb-go-sdk contains this problem in versions from v3.48.6 to v3.53.2. The fix for this problem has been released in version v3.53.3. Users are advised to upgrade. Users unable to upgrade should implement the `fmt.Stringer` interface in your custom credentials type with explicit stringify of object state.

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.
