Detection & IOCsextracted from sources · hover to see the quote
- →Detect specially crafted protocol messages sent to a Routing and Remote Access Service (RRAS) server over the network, originating from authenticated (low-privilege) users, which may indicate exploitation attempts targeting the heap-based buffer overflow. ↗
- →Monitor RRAS service (svchost.exe hosting RemoteAccess) for anomalous memory activity or crashes consistent with heap-based buffer overflow exploitation, particularly from network-originated requests by non-admin authenticated users. ↗
- →Flag exploitation attempts from any authenticated low-privilege account — no admin or elevated privileges are required to trigger this vulnerability. ↗
- ·Exploitation is assessed as unlikely by Microsoft as of the patch release; no public exploit or active in-the-wild exploitation has been confirmed. ↗
- ·The vulnerability requires the RRAS role to be enabled and reachable on the target Windows server; environments not running RRAS are not exposed. ↗
- ·Attack requires network access and valid credentials (PR:L), meaning unauthenticated external attackers cannot directly exploit this without first obtaining credentials. ↗

Windows Routing and Remote Access Service (RRAS) Remote Code Execution Vulnerability
vendor_msrc·2025-06-10·CVSS 8.8
CVE-2025-33064 [HIGH] CWE-122 Windows Routing and Remote Access Service (RRAS) Remote Code Execution Vulnerability
Windows Routing and Remote Access Service (RRAS) Remote Code Execution Vulnerability
Description: Heap-based buffer overflow in Windows Routing and Remote Access Service (RRAS) allows an authorized attacker to execute code over a network.
FAQ: How could an attacker exploit this vulnerability?
An authenticated attacker could send a specially crafted protocol message to a Routing and Remote Access Service (RRAS) server, which could lead to remote code execution (RCE) on the RAS server machine.
FAQ: According to the CVSS metric, privileges required is low (PR:L). What does that mean for this vulnerability?
Any authenticated attacker could trigger this vulnerability. It does not require admin or other elevated privileges.

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information.
