Common Vulnerabilities and Exposures assigned an identifier CVE-2008-7293 to the following vulnerability: Name: CVE-2008-7293 URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-7293 Assigned: 20110809 Reference: http://code.google.com/p/browsersec/wiki/Part2 #Same-origin_policy_for_cookies Reference: http://michael-coates.blogspot.com/2010/01/cookie-forcing-trust-your-cookies-no.html Reference: http://scarybeastsecurity.blogspot.com/2008/11/cookie-forcing.html Reference: http://scarybeastsecurity.blogspot.com/2011/02/some-less-obvious-benefits-of-hsts.html Reference: https://bugzilla.mozilla.org/show_bug.cgi?id=660053 Reference: http://hacks.mozilla.org/2010/08/firefox-4-http-strict-transport-security-force-https/ Mozilla Firefox before 4 cannot properly restrict modifications to cookies established in HTTPS sessions, which allows man-in-the-middle attackers to overwrite or delete arbitrary cookies via a Set-Cookie header in an HTTP response, related to lack of the HTTP Strict Transport Security (HSTS) includeSubDomains feature, aka a "cookie forcing" issue.
The only way I know of to correct this is to upgrade to Firefox 4 or newer.
Statement: This issue was addressed in Red Hat Enterprise Linux 5 and 6 by rebasing Firefox to 10.0.0 ESR.
