Fortinet FortiAnalyzer - Cross-Site Request Forgery

text exploit Source: Exploit-DB

source: https://www.securityfocus.com/bid/63663/info

FortiAnalyzer is prone to a cross-site request-forgery vulnerability because it fails to properly validate HTTP requests.

Exploiting this issue may allow a remote attacker to perform certain unauthorized administrative actions in the context of the device running the affected application. Other attacks are also possible.

Versions prior to Fortianalyzer 4.3.7 and 5.0.5 are vulnerable.
