Summary

CVE-2017-7269 is a critical-severity Classic Buffer Overflow (CWE-120) vulnerability in Microsoft Internet Information Services. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique NTDS (T1003.003); 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-2017-7269 is a buffer overflow vulnerability (CWE-120) in the ScStoragePathFromUrl function within the WebDAV service of Internet Information Services (IIS) 6.0, specifically affecting Microsoft Windows Server 2003 R2. The flaw is triggered by a specially crafted PROPFIND request containing a long "If: <http://" header, which can corrupt memory during path handling.

Remote attackers with network access can exploit the issue without authentication or user interaction to execute arbitrary code on the server, as reflected in its CVSS 3.1 base score of 9.8. The vulnerability was exploited in the wild as early as July or August 2016.

Public references document the issue through vulnerability databases and include proof-of-concept exploit code on GitHub, along with discussion of unofficial micropatch options for unsupported systems; no official vendor patch is referenced for the end-of-life platform.
