Listen to this Post
CVE-2025-60703 is a high-severity vulnerability in Microsoft Windows Remote Desktop Services (RDS) stemming from an Untrusted Pointer Dereference (CWE-822) . The flaw exists because the affected software fails to properly validate a memory pointer before using it to access data . An attacker who already has local access to the system with low privileges can trigger this weakness . By sending a specially crafted sequence, the attacker can dereference an untrusted pointer, leading to memory corruption . This corruption allows the attacker to execute arbitrary code in a higher security context . Successful exploitation enables the attacker to elevate their privileges from a standard user to SYSTEM, the highest level of access on Windows . This gives the attacker complete control over the compromised machine, including the ability to install programs, view and alter data, and create new accounts . While the attack is local and requires authentication, it poses a significant risk in multi-user environments or as a post-exploitation step after an initial foothold is gained . Microsoft has rated the vulnerability with a CVSS score of 7.8, indicating a HIGH severity . The vulnerability affects a wide range of Windows products, including Windows 10, 11, and various Windows Server editions . Patches have been released as part of the November 2025 security updates .

Platform: Windows/Server
Version: 10/11/2008-2025
Vulnerability : Untrusted Pointer Dereference
Severity: HIGH
date: 2025-11-11
Prediction: Patched (Nov 2025)
What Undercode Say:
Analytics:
The vulnerability is caused by improper validation of memory pointers within the Remote Desktop Services component . This is a classic memory corruption issue that has been patched across the Windows ecosystem. Organizations should prioritize identifying all systems with RDS enabled.
Commands:
To check the installed Windows version and build number:
winver
To check the build number via command line:
systeminfo | findstr /B /C:"OS Name" /C:"OS Version"
To verify if the RDP service is running:
Get-Service -Name TermService
To check for the specific patch (e.g., KB5068905 on Server 2012 R2) :
Get-HotFix -Id KB5068905
How Exploit:
An authenticated local attacker with low privileges would execute a specially crafted application that triggers the untrusted pointer dereference in the RDS service . This causes the service to mishandle memory, allowing the attacker’s code to run with elevated privileges, ultimately leading to SYSTEM-level access . As of the disclosure date, no public exploit code has been released, but the technical nature of the flaw makes exploit development likely .
Protection from this CVE:
- Apply Patches: Install the November 2025 security updates from Microsoft immediately .
- Restrict Access: Limit local access to trusted users only and strictly enforce the principle of least privilege .
- Disable RDS: If Remote Desktop Services is not required, disable it to remove the attack surface.
- Network Segmentation: Isolate systems that require RDS to limit lateral movement in case of a breach .
- Monitor Logs: Watch for unusual privilege escalations or application behavior in security logs .
Impact:
A successful exploit allows an attacker to completely compromise the confidentiality, integrity, and availability of the affected system . An attacker can gain full administrative control (SYSTEM privileges), install backdoors, steal sensitive data, and use the compromised machine as a launching pad for lateral movement across the network . In enterprise environments, this can lead to widespread system compromise and data breaches.
