CVE-2002-1973 describes a buffer overflow vulnerability in the ISAPI extension (Isapi.cpp) of CHttpServer::OnParseError, specifically when built with Microsoft Foundation Class (MFC) static libraries in Visual C++ 5.0 and 6.0 (before SP3). This flaw affects products like BadBlue and allows remote attackers to trigger a denial of service through an access violation and crash, with potential for arbitrary code execution, by submitting a long query string that causes a parsing error. With a CVSS score of 7.5, it is considered highly severe due to its network-based attack vector, low attack complexity, and potential for complete compromise of confidentiality, integrity, and availability. While not listed in CISA's KEV catalog and lacking Metasploit or Nuclei modules, an ExploitDB entry (EDB-21601) exists, indicating public exploit code availability, though there is no evidence of active exploitation or significant community discussion.
