Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Client Execution (T1203); ranked in the top 0.0% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2019-0708 is a remote code execution vulnerability in Remote Desktop Services, formerly known as Terminal Services, that stems from a use-after-free flaw (CWE-416). It affects systems accepting RDP connections and carries a CVSS 3.1 base score of 9.8 reflecting network-accessible, unauthenticated attack vectors with high impact on confidentiality, integrity, and availability.

An unauthenticated attacker can exploit the issue simply by establishing an RDP session to the target and transmitting specially crafted requests, enabling arbitrary code execution on the affected system without any user interaction or credentials.

Public exploit code for both denial-of-service and remote code execution variants has been published on Packet Storm, confirming that working proof-of-concept implementations targeting the vulnerability are available.
