SiteBar: Multiple issues — GLSA 200711-05

Multiple issues have been identified in SiteBar that might allow execution of arbitrary code and arbitrary file disclosure.

Affected Packages

www-apps/sitebar on all architectures
Affected versions < 3.3.9
Unaffected versions >= 3.3.9

Background

SiteBar is a PHP application that allows users to store their bookmarks on a web server.

Description

Tim Brown discovered these multiple issues: the translation module does not properly sanitize the value to the "dir" parameter (CVE-2007-5491, CVE-2007-5694); the translation module also does not sanitize the values of the "edit" and "value" parameters which it passes to eval() and include() (CVE-2007-5492, CVE-2007-5693); the log-in command does not validate the URL to redirect users to after logging in (CVE-2007-5695); SiteBar also contains several cross-site scripting vulnerabilities (CVE-2007-5692).

Impact

An authenticated attacker in the "Translators" or "Admins" group could execute arbitrary code, read arbitrary files and possibly change their permissions with the privileges of the user running the web server by passing a specially crafted parameter string to the "translator.php" file. An unauthenticated attacker could entice a user to browse a specially crafted URL, allowing for the execution of script code in the context of the user's browser, for the theft of browser credentials or for a redirection to an arbitrary web site after login.

Workaround

There is no known workaround at this time.

Resolution

All SiteBar users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=www-apps/sitebar-3.3.9"
