CVE-2016-0856 – Advantech WebAccess datacore Service datacore.exe AlarmMessage sprintf Stack-Based Buffer Overflow Remote Code Execution Vulnerability

https://notcve.org/view.php?id=CVE-2016-0856

Multiple stack-based buffer overflows in Advantech WebAccess before 8.1 allow remote attackers to execute arbitrary code via unspecified vectors. Múltiples desbordamientos de buffer basado en pila en Advantech WebAccess en versiones anteriores a 8.1 permiten a atacantes remotos ejecutar código arbitrario a través de vectores no especificados. This vulnerability allows remote attackers to execute arbitrary code on vulnerable instances of Advantech WebAccess. Authentication is not required to exploit this vulnerability. The specific flaw exists within the implementation of the 0x5228 IOCTL in the Kernel subsystem. A stack-based buffer overflow vulnerability exists in a call to sprintf with the AlarmMessage parameter. • http://www.zerodayinitiative.com/advisories/ZDI-16-100 http://www.zerodayinitiative.com/advisories/ZDI-16-101 http://www.zerodayinitiative.com/advisories/ZDI-16-102 http://www.zerodayinitiative.com/advisories/ZDI-16-103 http://www.zerodayinitiative.com/advisories/ZDI-16-106 http://www.zerodayinitiative.com/advisories/ZDI-16-108 http://www.zerodayinitiative.com/advisories/ZDI-16-109 http://www.zerodayinitiative.com/advisories/ZDI-16-110 http://www.zerodayinitiative.com/advisories/ZDI-16-111 http: • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
