CVE Reference:   CVE-2009-1195   (Links to External Site)
Date:  Oct 16 2010
Impact:   Modification of user information
Fix Available:  Yes  Vendor Confirmed:  Yes  Exploit Included:  Yes  
Version(s): 2.2.11
Description:   A vulnerability was reported in Apache. A local user can bypass security restrictions.

The "Options" and "AllowOverride" directives are not properly processed. A local user can enable Server Side Includes (SSI) even when the "IncludesNoEXEC" option is set.

If the system is configured with "AllowOverride Options=IncludesNoEXEC", a local user can place "Options Includes" in a '.htaccess' file to cause Server Side Includes to be enabled with exec privileges.

If the system is configured with "AllowOverride Options=IncludesNoEXEC" and with "Options IncludesNoExec" enabled in the same <Directory> context, a local user can place "Options +IncludesNoExec" in a '.htaccess' file to cause Server Side Includes to be enabled with exec privileges.

Jonathan Peatfield reported this vulnerability.

Impact:   A local user can enable Server Side Includes in certain cases when SSI execution should be prohibited.
Solution:   Sun has issued a fix.
