Summary
FreeRDP before 3.29.0 fails to properly validate server-supplied RDPDR paths in drive redirection, allowing attackers to access prefix-sibling paths outside the configured shared root. A malicious RDP server can read, write, delete, and enumerate files in sibling directories by sending non-rooted paths that bypass the shared-root boundary check.
A flaw was found in FreeRDP, an open-source implementation of the Remote Desktop Protocol (RDP). This vulnerability allows a malicious RDP server to bypass security checks during drive redirection.
By sending specially crafted paths, the server can access, read, write, delete, and list files in directories outside the intended shared folder on the client's system. This could lead to unauthorized access and manipulation of sensitive data.
Red Hat severity: Moderate — CVSS 6.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L). Weakness: CWE-22.
Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9. Will not fix / out of support: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7.
Red Hat does not currently list a fixing RHSA for this CVE.

Mitigation checklist
- To mitigate this vulnerability, disable drive redirection when connecting to untrusted RDP servers. This can typically be configured within the FreeRDP client settings or by avoiding the use of the `/drive` or `/home-drive` options when initiating an RDP session. Disabling drive redirection prevents the server from manipulating local file paths.
