The masort function in lib/functions.php in phpLDAPadmin 1.2.x before 1.2.2 allows remote attackers to execute arbitrary PHP code via the orderby parameter (aka sortby variable) in a query_engine action to cmd.php, as exploited in the wild in October 2011.

Update to the latest upstream development code to fix CVE-2011-4074 and CVE-2011-4075 (XSS and code injection vulnerabilities in versions <= 1.2.1.1)

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The version of phpLDAPadmin installed on the remote host does not sanitize input to the 'orderby' parameter of the 'cmd.php' script when 'cmd' is set to 'query_engine' before using it in a call to 'create_function()'.

An unauthenticated, remote attacker can leverage this issue to execute arbitrary PHP code on the affected host, subject to the privileges under which the web server runs.

Two vulnerabilities have been discovered in phpLDAPadmin, a web-based interface for administering LDAP servers. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2011-4074     Input appended to the URL in cmd.php (when 'cmd' is set     to '_debug') 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.

  - CVE-2011-4075     Input passed to the 'orderby' parameter in cmd.php (when     'cmd' is set to'query_engine', 'query' is set to 'none',     and 'search' is set to e.g.'1') is not properly     sanitised in lib/functions.php before being used in     a'create_function()' function call. This can be     exploited to inject and execute arbitrary PHP code.
