Vulnerabilities > CVE-2023-22733 - Information Exposure Through Log Files vulnerability in Shopware
Summary
Shopware is an open source commerce platform based on Symfony Framework and Vue js. In affected versions the log module would write out all kind of sent mails. An attacker with access to either the local system logs or a centralized logging store may have access to other users accounts. This issue has been addressed in version 6.4.18.1. For older versions of 6.1, 6.2, and 6.3, corresponding security measures are also available via a plugin. For the full range of functions, we recommend updating to the latest Shopware version. Users unable to upgrade may remove from all users the log module ACL rights or disable logging.
Vulnerable Configurations
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.
