CVE-2011-0026 is a critical integer signedness error in the SQLConnectW function within Microsoft Data Access Components (MDAC) and Windows Data Access Components (WDAC), affecting various Windows operating systems. This vulnerability allows remote attackers to execute arbitrary code by supplying a specially crafted, long Data Source Name (DSN) argument, bypassing signed comparison checks and leading to a buffer overflow. With a CVSS score of 9.3, it presents a severe risk due to its network-based attack vector, medium attack complexity, and complete compromise of confidentiality, integrity, and availability. Despite its high severity and EPSS score, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
