I found a doubledot vulnerability on a site running Informix database. I can read of any file on the system by putting /../ into the url. But so far I have only found two sites with this problem. The site is running Netscape-Enterprise/4.0 on Solaris according to Netcraft.comI have tested this on Apache 1.3.12/Solaris 7/webdriver 4.10.UC1, Netscape Enterprise 3.6/NT4/webdriver 4.10.TC1, IIS 5.0/Win2K/webdriver 4.11.TC1, Apache 1.3.12/Linux/webdriver 4.10.UC1, running on Informix Universal Server 9.2x on Linux, NT4 and Win2K with the web datablade 4.x. All do not have this problem. All the platforms I have tested simply close the connection immediately, giving a zero-sized reply. I also tested using MIvalObj= instead of LO=, MIvalObj gives a 500 reply.
[Snip] Apache v1.3.22 running on Novell NetWare returns a "Bad request" error message, so it's not vulnerable here either. I suspect that Apache is secure in this regard since the OS has very little to do with this type of exploit. Randolf Richardson - rr () 8x ca Inter-Corporate Computer & Network Services, Inc.
