Описание
A path traversal vulnerability exists in rsync. It stems from behavior enabled by the --inc-recursive option, a default-enabled option for many client options and can be enabled by the server even if not explicitly enabled by the client. When using the --inc-recursive option, a lack of proper symlink verification coupled with deduplication checks occurring on a per-file-list basis could allow a server to write files outside of the client's intended destination directory. A malicious server could write malicious files to arbitrary locations named after valid directories/paths on the client.
Отчет
Red Hat rates this flaw to have moderate severity as it depends on specific configurations for the attack to succeed, symbolic link syncing must be enabled (explicitly by providing the --links option or implicitly such as with --archive) and the client must connect to a malicious or compromised server.
Within regulated environments, a combination of the following controls acts as a significant barrier to successfully exploiting a CWE-35: Path Traversal: '.../...//' vulnerability and therefore downgrades the severity of this particular CVE from Moderate to Low.
The principle of least privilege is enforced through non-root containers, security context constraints, and pod-level security policies, which limit the actions a process can perform and reduce the potential impact of a successful exploit or misconfiguration. The platform enforces process isolation, ensuring workloads run with minimal privileges and are securely separated to limit the impact of path traversal attempts. Additionally, 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.
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.
