The disclosed vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.
The vulnerability exists due to a banner disclosure. A remote attacker can use the HTTP response header that is normally not available to the attacker and obtain extraneous product information, such as OS and software components.
5) Cross-site request forgery (CVE-ID: CVE-2018-8844)
CWE-ID: CWE-352 - Cross-Site Request Forgery (CSRF)
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The disclosed vulnerability allows a remote attacker to perform CSRF attacks.
The vulnerability exists due to the web application does not, or cannot, sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request. A remote attacker can trick the victim into visiting a specially crafted specially crafted HTML page or URL, conduct cross-site request forgery attack and perform arbitrary actions.
