The web vulnerability allows remote attacker to inject own malicious script codes on the client-side of the vulnerable module or service. A client-side cross site scripting web vulnerability is located in the search engine. The web vulnerability could allow an attacker to execute javascript in the web-browser of the user or administrator to compromise session credentials. The attacker can connect to a third account to trigger the issue without knowing the password. The security risk of the client-side web vulnerability is estimated as medium with a cvss (common vulnerability scoring system) count of 3.1. Exploitation of the client-side cross site vulnerability requires no privileged web-application user account and low or medium user interaction. Successful exploitation of the vulnerability results in non-persistent phishing, session hijacking, non-persistent external redirect to malicious sources and client-side manipulation of affected or connected web module context. Request Method(s): [+] POST Vulnerable Module(s): [+] Add (Input) Vulnerable Parameter(s): [+] location_for_search Proof of Concept (PoC): ======================= The vulnerability can be exploited by remote attackers without privileged user account and with low user interaction.
