Description Jan Lieskovsky 2012-03-05 10:26:21 UTC

Originally (2012-03-01), the following cross-site (XSS) flaws were reported against LDAP Account Manager Pro (from Secunia advisory [1]):
* 1) Input passed to e.g. the "filteruid" POST parameter when filtering result sets in lam/templates/lists/list.php (when "type" is set to a valid value) is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

* 2) Input passed to the "filter" POST parameter in lam/templates/3rdParty/pla/htdocs/cmd.php (when "cmd" is set to "export" and "exporter_id" is set to "LDIF") is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

* 3) Input passed to the "attr" parameter in lam/templates/3rdParty/pla/htdocs/cmd.php (when "cmd" is set to "add_value_form" and "dn" is set to a valid value) is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

Later (2012-03-03), it was reported:
[3] http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=662050#15

that subset (for 'export', 'add_value_form', and 'dn' variables) of these security flaws is applicable also against the code of PhpLDAPadmin, a web-based LDAP client.

Patches from LDAP Account Manager, which are applicable to PphLDAPAdmin:
[4] http://lam.cvs.sourceforge.net/viewvc/lam/lam/templates/3rdParty/pla/lib/export_functions.php?r1=1.4&r2=1.5
[5] http://lam.cvs.sourceforge.net/viewvc/lam/lam/templates/3rdParty/pla/htdocs/export.php?r1=1.1&r2=1.2
[6] http://lam.cvs.sourceforge.net/viewvc/lam/lam/templates/3rdParty/pla/htdocs/add_value_form.php?r1=1.6&r2=1.7

Comment 1 Jan Lieskovsky 2012-03-05 10:38:58 UTC

These issues affect the versions of the phpldapadmin package, as shipped with Fedora release of 15 and 16. Please schedule an update.

--

These issues affect the versions of the phpldapadmin package, as shipped with Fedora EPEL 6 and Fedora EPEL 5 (though the latter one might require the proposed patches above to be backported to older PhpLDAPAdmin version being present). Please schedule an update.

Comment 5 Dmitry Butskoy 2012-03-06 14:55:03 UTC

It seems that the patches present perform fix for the bundled, reduced version in LDAP Account manager only. Better to ask upstream anyway.

Reported upstream, https://sourceforge.net/tracker/?func=detail&aid=3497660&group_id=61828&atid=498546
