GroupWise 7 attached bugs
Product: GroupWise 7
OS: Windows xp
Find two types of vulnerabilities in this client is a correo.Una xss and the
other a denial of service but I am also appears to be run arbitrary code.
XSS in web access
You can run Javascript code to send an attachment with poorly trained jpg
extension.
Denial of Service
By sending an attachment with the maximum allowed characters makes the program
break, if we analyse it with a debugger the result is as follows.
Access violation when writing to [02a68a83]
It makes a difference that the extension is used in the proof of concept
because if we send the file with this extension html penalties to visualize the
mail is broken, in the case of other extensions is necessary to preview the
attachment.
I leave here with a zip and two files created, to test the concept.
