Name of the Vulnerable Software and Affected Versions: Advantech WebAccess versions prior to 8.3
Description: An Untrusted Pointer Dereference issue was discovered in Advantech WebAccess, which may allow an attacker to cause the program to use an invalid memory address, resulting in a program crash. The issue affects multiple functions, including SQLSetConnectOption, SQLFreeConnect, SQLExecute, SQLFetchScroll, SQLDescribeParam, SQLExecDirect, SQLSetEnvAttr, SQLConnect, SQLFreeEnv, SQLPrepare, SQLNumResultCols, SQLParamData, SQLDisconnect, SQLAllocStmt, SQLSetParam, SQLFetch, SQLFreeStmt, SQLCancel, SQLSetStmtAttr, and SQLPutData.
