Directory traversal in CitrusDB
RedTeam found a directory traversal vulnerability in CitrusDB which results in inclusion of any accessible local .php file. Details ======= Product: CitrusDB Affected Version: 0.3.6, probably <= 0.3.5, too Immune Version: none (2005-02-03) OS affected: all Security-Risk: medium Remote-Exploit: no Vendor-URL: http://www.citrusdb.org Vendor-Status: informed Advisory-URL: http://www.redteam-pentesting.de/advisories/rt-sa-2005-005 Advisory-Status: public CVE: CAN-2005-0411 (https://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0411#) Introduction ============ Description from vendor: "CitrusDB is an open source customer database application that uses PHP and a database backend (currently MySQL) to keep track of customer information, services, products, billing, and customer service information." It is possible to include any local accessible .php file. More Details ============ CitrusDB uses a wrapper script (./citrusdb/tools/index.php) to load different modules and tools. The GET parameter "load" specifies which file should be included. With a relative path appended any .php file, that may be accessed by the script, on the server may be included. Proof of Concept ================ To include /tmp/exploit.php use: http://<target>/citrusdb/tools/index.php?load=../../../../../../tmp/exploit Note: You need to be logged in to access this url. Workaround ========== n/a (2005-02-03) Fix === n/a (2005-02-03) Security Risk ============= The security risk is rated medium. An attacker needs to be able to create a .php file on the local filesystem which is normally a high barrier but in shared hosting enviroments this may be easier.
