Description Vincent Danen 2011-10-24 18:14:40 UTC
Two flaws were reported [1],[2],[3] in phpLDAPAdmin 1.2.1.1 and probably earlier versions.

1) 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.

2) 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.

Both issues are fixed in git: issue #1 [4] and issue #2 [5].

I am unsure whether these flaws only affect 1.2.x or if they also affect older 1.x and 0.x.

Comment 1 Vincent Danen 2011-10-24 18:16:54 UTC
Created phpldapadmin tracking bugs for this issue

Affects: fedora-all [bug 748538]
Affects: epel-6 [bug 748539]

Comment 2 Vincent Danen 2011-10-25 15:29:06 UTC
Issue #1 was assigned the name CVE-2011-4074 and issue #2 was assigned the name CVE-2011-4075.

Comment 3 Dmitry Butskoy 2011-10-26 15:12:49 UTC
CVE-2011-4075 (issue #2) seems to affect 1.0.x and 0.9.8.x as well. I've patched 1.0.2 (el5) and 0.9.8.5 (el4) for this.

Updates for f14/f15/f16 and el4/el5/el6 should appear in updates-testing soon.

Comment 4 Jan Lieskovsky 2011-10-27 11:56:03 UTC
Yes another security flaw in phpLDAPadmin -- local file inclusion in "common.php" file via the "Accept-Language" HTTP header:

[6] http://www.securityfocus.com/bid/50328/exploit

Relevant exploit:
[7] http://downloads.securityfocus.com/vulnerabilities/exploits/50328.java

The patch applied by phpLDAPadmin v0.9.8.5 version would fix this issue too.

Comment 5 Jan Lieskovsky 2011-10-27 12:10:31 UTC
CVE request for the third issue:

Comment 6 Dmitry Butskoy 2011-10-27 12:35:24 UTC
for comment #4 :

The "common.php" issue was fixed even in 0.9.8.3, and such a version was in Fedora/EPEL since 2006. It is not actual for us at least last 5 years.

0.9.8.5 is not a "fix" for this particular issue, I just have updated to the latest subversion in that branch, additionally to the patch to fix CVE-2011-4075 .

Comment 7 Kurt Seifried 2011-10-27 15:18:12 UTC
Confirmed vulnerable in 0.9.7, and fixed in 0.9.8 (common.php was moved into /lib/ and majorly refactored, no more include()'s).

Comment 8 Vincent Danen 2011-10-27 21:13:07 UTC
Since this third issue only affects EPEL4, I filed a new bug for it: bug #749677.

Comment 9 Fedora Update System 2011-11-25 01:52:48 UTC
phpldapadmin-1.2.1.1-2.20111006git.fc16 has been pushed to the Fedora 16 stable repository.  If problems still persist, please make note of it in this bug report.

Comment 10 Fedora Update System 2011-11-25 01:56:13 UTC
phpldapadmin-1.2.1.1-2.20111006git.fc14 has been pushed to the Fedora 14 stable repository.  If problems still persist, please make note of it in this bug report.
