A low privileged process can crash CmdVirth.exe to decrease the port's connection count followed by process hollowing a CmdVirth.exe instance with malicious code to obtain a handle to \"cmdServicePort\". Once this occurs, a specially crafted message can be sent to \"cmdServicePort\" using \"FilterSendMessage\" API. This can trigger an out-of-bounds write if lpOutBuffer parameter in FilterSendMessage API is near the end of specified buffer bounds. The crash occurs when the driver performs a memset operation which uses a size beyond the size of buffer specified, causing kernel crash.", "severity": [ { "type": "CVSS_V3", "score": "CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H" } ], "affected": [], "references": [ { "type": "ADVISORY", "url": "https://nvd.nist.gov/vuln/detail/CVE-2019-3973" }, { "type": "WEB", "url": "https://www.tenable.com/security/research/tra-2019-34" } ], "database_specific": { "cwe_ids": [ "CWE-787" ], "severity": "MODERATE", "github_reviewed": false, "github_reviewed_at": null, "nvd_published_at": "2019-07-17T21:15:00Z" } }
