CVE-2011-0026
HighSummary
Błąd związany z podpisywaniem liczb całkowitych w funkcji SQLConnectW w ODBC API (odbc32.dll) w Microsoft Data Access Components (MDAC) 2.8 SP1 i SP2 oraz Windows Data Access Components (WDAC) 6.0, umożliwia zdalnym atakującym wykonanie dowolnego kodu poprzez długi ciąg w nazwie źródła danych (DSN) oraz spreparowany argument szDSN, co prowadzi do przepełnienia bufora.
Risk Assessment
Podatność ta może zostać wykorzystana przez zdalnych atakujących do przejęcia kontroli nad systemem, co stwarza poważne zagrożenie dla bezpieczeństwa organizacji.
Recommendation
Zaleca się aktualizację Microsoft Data Access Components do najnowszej wersji oraz monitorowanie systemów pod kątem nieautoryzowanych prób dostępu.

- CVE-2026-124494Critical
SunEditor before 3.4.0 contains a stored cross-site scripting vulnerability because the html.clean() sanitizer's _normalizeURL() function decodes named entities like : to an empty string. Attackers can inject href values such as javascript: that pass the _isSafeURL() check but are decoded by browsers, executing JavaScript when victims click stored links.
- CVE-2026-124493Critical
SunEditor before 3.4.0 contains a stored cross-site scripting vulnerability in the DocumentType constructor that injects header textContent into innerHTML without HTML escaping. Attackers can store entity-encoded HTML in h1-h6 headers that executes JavaScript when editors using document:header mode initialize, enabling session cookie theft.
- CVE-2026-124490Critical
OpenEMR before 8.3.0 contains a path traversal vulnerability in the RingCentral RCFaxClient disposeDocument() method of oe-module-faxsms that allows authenticated attackers to read and write arbitrary files via the file_path parameter. Attackers can use action=download to read credentials and source code, or action=setup with base64 content to write web-executable files for code execution.
Original NVD description (English source)
Integer signedness error in the SQLConnectW function in an ODBC API (odbc32.dll) in Microsoft Data Access Components (MDAC) 2.8 SP1 and SP2, and Windows Data Access Components (WDAC) 6.0, allows remote attackers to execute arbitrary code via a long string in the Data Source Name (DSN) and a crafted szDSN argument, which bypasses a signed comparison and leads to a buffer overflow, aka "DSN Overflow Vulnerability."
