More information about the product is available here: http://fuzzymonkey.org/newfuzzy/software/perl/classifieds/readme.html Description MyClassifieds SQL Version is vulnerable to a SQL injection attack. The problem is due to improper sanitization of user input for the $email variable. A remote attacker could insert arbitrary SQL code in the $email variable. The passwords of the users can be written into a file and made world readable. Example: If the value of $email is aaa (at) aaa (dot) com [email concealed]' OR 1=1 INTO OUTFILE '/<directory-path>/pass.txt, the SQL request becomes: select passmd5 from people where email=' aaa (at) aaa (dot) com [email concealed]' OR 1=1 INTO OUTFILE '/<directory-path>/pass.txt' and the passwords of the users can be written into the file pass.txt.
