A flaw was found in rsync. This vulnerability arises from a race condition during rsync's handling of symbolic links. Rsync's default behavior when encountering symbolic links is to skip them. If an attacker replaced a regular file with a symbolic link at the right time, it was possible to bypass the default behavior and traverse symbolic links. Depending on the privileges of the rsync process, an attacker could leak sensitive information, potentially leading to privilege escalation.
Отчет
Within regulated environments, a combination of the following controls acts as a significant barrier to successfully exploiting a CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') vulnerability and therefore downgrades the severity of this particular CVE from Moderate to Low. Red Hat enforces the principle of least functionality, ensuring that only essential features, services, and ports are enabled. The environment leverages malicious code protections such as IPS/IDS and antimalware solutions that detect and respond to indicators in real time, limiting the impact of exploitation attempts. Static code analysis and peer code review techniques are used to execute robust input validation and error-handling mechanisms to ensure all user inputs are thoroughly validated, preventing improperly validated inputs from causing system instability, exposing sensitive data, or escalating risks. In the case of successful exploitation, detection and containment controls are in place to limit impacts by alerting on anomalous system behavior in real time, while process isolation and automated orchestration via Kubernetes minimize the likelihood of concurrent execution scenarios that would trigger the race condition and help contain the impact to a single process.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
