An attacker can inject values into a PostgreSQL connection string by providing a parameter surrounded by single quotes.
Depending on how the library is used in the client software, this may allow an attacker to bypass the login process, gain access to the server's IP address, etc.
The vulnerability is fixed in ADOdb versions 5.20.21 (952de6c4273d9b1e91c2b838044f8c2111150c29) and 5.21.4 or later (b4d5ce70034c5aac3a1d51d317d93c037a0938d2).
The simplest patch is to delete line 29 in drivers/adodb-postgres64.inc.php:
diff --git a/drivers/adodb-postgres64.inc.php b/drivers/adodb-postgres64.inc.php
index d04b7f67..729d7141 100644
--- a/drivers/adodb-postgres64.inc.php
+++ b/drivers/adodb-postgres64.inc.php
@@ -26,7 +26,6 @@ function adodb_addslashes($s)
{
$len = strlen($s);
if ($len == 0) return "''";
- if (strncmp($s,"'",1) === 0 && substr($s,$len-1) == "'") return $s; // already quoted
return "'".addslashes($s)."'";
}
Ensure the parameters passed to ADOConnection::connect() or related functions (nConnect(), pConnect()) are not surrounded by single quotes.
