Exposure of sensitive information to an unauthorized actor in Windows Snipping Tool allows an unauthorized attacker to perform spoofing over a network.
AnalysisAI
Windows Snipping Tool leaks sensitive information to unauthenticated network attackers via user interaction, enabling spoofing attacks. The vulnerability affects Windows 10 (versions 1607, 1809, 21H2, 22H2) and Windows 11 (versions 22H3, 23H2, 24H2, 25H2, 26H1), as well as Windows Server 2012 through 2025. Microsoft has released patches for all affected versions; exploitation requires user interaction but no specialized technical knowledge.
Technical ContextAI
The Windows Snipping Tool, a built-in screenshot capture utility available across Windows client and server editions, improperly handles sensitive data exposure as described by CWE-200 (Information Exposure). The vulnerability mechanism involves the tool disclosing confidential information over the network without proper access controls, allowing remote actors to intercept or infer sensitive details that were intended to remain private. This affects multiple Windows kernel versions from Windows Server 2012 (6.2.9200) through Windows 11 26H1 (10.0.28000), each with distinct patched build numbers. The network-based attack vector combined with requirement for user interaction (UI:R in CVSS) suggests the exposure occurs during snip sharing, clipboard operations, or cloud synchronization features.
RemediationAI
Apply vendor-released patches from Microsoft to achieve remediation. For Windows 10 Version 1607, update to build 10.0.14393.9060 or later; for Version 1809, update to 10.0.17763.8644 or later; for Version 21H2, update to 10.0.19044.7184 or later; for Version 22H2, update to 10.0.19045.7184 or later. For Windows 11, update Version 22H3 to 10.0.22631.6936 or later, Version 23H2 to 10.0.22631.6936 or later, Version 24H2 to 10.0.26100.32690 or later, Version 25H2 to 10.0.26200.8246 or later, and Version 26H1 to 10.0.28000.1836 or later. Windows Server patches include Server 2012/2012 R2 to 6.2.9200.26026 / 6.3.9600.23132, Server 2016 to 10.0.14393.9060, Server 2019 to 10.0.17763.8644, Server 2022 to 10.0.20348.5020, and Server 2025 to 10.0.26100.32690. Patch status should be verified through Windows Update or manual deployment via Microsoft Update Catalog. Until patched, restrict Snipping Tool access on sensitive systems if alternative screenshot tools are available, and educate users to avoid sharing sensitive snips via untrusted channels.
