AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
Network RDP access with low-privilege credentials is the sole prerequisite; only confidentiality is impacted as uninitialized memory is disclosed, not modified.

Use of uninitialized resource in Windows RDP allows an authorized attacker to disclose information over a network.
AnalysisAI
Information disclosure via uninitialized resource use in Windows Remote Desktop Protocol (RDP) exposes sensitive memory contents to authenticated remote attackers across a wide range of Microsoft Windows desktop and server editions. The CVSS vector (AV:N/AC:L/PR:L/UI:N) confirms this is exploitable over the network by any low-privileged authenticated user with no complexity or interaction requirements, yielding high confidentiality impact. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the attacker hold valid Windows credentials sufficient for an RDP login (low-privilege authorized user, as indicated by PR:L in the CVSS vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 6.5 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N) accurately reflects a network-reachable information disclosure requiring only low-privilege credentials. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has obtained valid low-privilege Windows credentials - through phishing, credential stuffing, or lateral movement - connects to a target system over RDP on TCP/3389 and triggers the uninitialized resource condition during the RDP session, causing the service to transmit uninitialized memory contents back to the client. Depending on what resides in uninitialized memory at exploitation time, the attacker may recover sensitive data such as session tokens, cryptographic keys, or other process memory, facilitating privilege escalation or further lateral movement. … |
| Remediation | The primary remediation is to apply the vendor-released patch distributed by Microsoft; the advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-57982 provides the specific KB articles and update packages for each affected Windows version. … Detailed patch versions, workarounds, and compensating controls in full report. |
