Some vulnerabilities have been reported in HP Instant Support, which potentially can be exploited by malicious people to bypass certain security restrictions and compromise a user's system.
1) Some vulnerabilities are caused due to boundary errors within the "ExtractCab()", "GetFileTime()", "MoveFile()", and "RegistryString()" methods of HPISDataManager.dll. These can be exploited to cause a buffer overflow via an overly long string passed to the affected methods when a user e.g. visits a malicious web page.
2) The HPISDataManager.dll ActiveX contains the insecure methods "AppendStringToFile()", "DownloadFile()", "StartApp()", and "DeleteSingleFile()", which can be exploited to e.g. overwrite, delete, and execute arbitrary files on a user's system and download files into the location of the ActiveX component by tricking a user into visiting a malicious web page.
The vulnerabilities are reported in HP Instant Support HPISDataManager.dll version 18.104.22.168 and earlier.
Solution: Update to version 22.214.171.124. Choose "launch an online diagnostic session" at:
