libraries/server_synchronize.lib.php in the Synchronize implementation in phpMyAdmin 3.x before 3.3.10.2 and 3.4.x before 3.4.3.1 does not properly quote regular expressions, which allows remote authenticated users to inject a PCRE e (aka PREG_REPLACE_EVAL) modifier, and consequently execute arbitrary PHP code, by leveraging the ability to modify the SESSION superglobal array.

The remote host is affected by the vulnerability described in GLSA-201201-01 (phpMyAdmin: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in phpMyAdmin. Please       review the CVE identifiers and phpMyAdmin Security Advisories referenced       below for details.
  Impact :

    Remote attackers might be able to insert and execute PHP code, include       and execute local PHP files, or perform Cross-Site Scripting (XSS)       attacks via various vectors.
  Workaround :

    There is no known workaround at this time.

The remote host contains a version of phpMyAdmin - 3.3.x less than 3.3.10.2 or 3.4.x less than 3.4.3.1 - that is affected by multiple vulnerabilities :

  - An error in the file     'libraries/auth/swekey/swekey.auth.lib.php' allows an     attacker to modify the 'SESSION' superglobal array.
    (CVE-2011-2505)

  - An error in the file     'setup/lib/ConfigGenerator.class.php' does not properly     handle PHP comment-closing delimiters. This can allow     an attacker inject static code via a modified 'SESSION'     superglobal array. (CVE-2011-2506)

  - An error in the file     'libraries/server_synchronize.lib.php' does not properly     call the 'preg_replace' function. This can allow an     attacker to execute arbitrary code via a modified     'SESSION' superglobal array. (CVE-2011-2507)

  - An local file inclusion error exists in the     'PMA_displayTableBody' function in the file     'libraries/display_tbl.lib.php' that can allow an     attacker to obtain sensitive information or execute     code in file already present on the host.
    (CVE-2011-2508)

Several vulnerabilities were discovered in phpMyAdmin, a tool to administrate MySQL over the web. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2011-2505     Possible session manipulation in Swekey authentication.

  - CVE-2011-2506     Possible code injection in setup script, in case session     variables are compromised.

  - CVE-2011-2507     Regular expression quoting issue in Synchronize code.

  - CVE-2011-2508     Possible directory traversal in MIME-type     transformation.

  - CVE-2011-2642     Cross site scripting in table Print view when the     attacker can create crafted table names.

  - No CVE name yet

    Possible superglobal and local variables manipulation in     Swekey authentication. (PMASA-2011-12)

The oldstable distribution (lenny) is only affected by CVE-2011-2642, which has been fixed in version 2.11.8.1-5+lenny9.

Versions of phpMyAdmin 3.3.x earlier than 3.3.10.2 and 3.4.x earlier than 3.4.3.1 are potentially affected by multiple vulnerabilities : 

  - It is possible to manipulate the PHP session superglobal usig some of the Swekey authentication code. (PMASA-2011-5)

  - An unsanitized key from the Servers array is written in a comment of the generated config, which could allow an attacker to close the comment and inject code. (PMASA-2011-6)

  - It is possible to use a null byte to truncate the pattern string which would allow an attacker to inject the /e modifier causing the pre_replace function to execute its second argument as PHP code. (PMASA-2011-7)

  - An issue exists in the MIME-type transformation code, which allows for directory traversal. (PMASA-2011-8)

The phpMyAdmin development team reports :

It was possible to manipulate the PHP session superglobal using some of the Swekey authentication code. This could open a path for other attacks.

An unsanitized key from the Servers array is written in a comment of the generated config. An attacker can modify this key by modifying the SESSION superglobal array. This allows the attacker to close the comment and inject code.

Through a possible bug in PHP running on Windows systems a NULL byte can truncate the pattern string allowing an attacker to inject the /e modifier causing the preg_replace function to execute its second argument as PHP code.

Fixed filtering of a file path in the MIME-type transformation code, which allowed for directory traversal.
