Stack-based buffer overflow in Hummingbird.XWebHostCtrl.1 ActiveX control (hclxweb.dll) in Hummingbird Xweb ActiveX Control 13.0 and earlier allows remote attackers to execute arbitrary code via a long PlainTextPassword property. NOTE: code execution might not be possible in 13.0.
Xconfig in Hummingbird Exceed before 9.0.0.1, when the Screen Definition is password-protected, allows local users to access certain options by switching to another tab, then switching back to the original tab.
Hummingbird Exceed 6.0.1.0 inadvertently includes a DLL that was meant for development and testing, which logs user names and passwords in cleartext in the test.log file.
