[1] 150085 Slow HTTP POST vulnerability Severity Potential Vulnerability - Level 3 Group Information Disclosure Threat The web application is possibly vulnerable to a "slow HTTP POST" Denial of Service (DoS) attack. This is an application-level DoS that consumes server resources by maintaining open connections for an extended period of time by slowly sending traffic to the server. If the server maintains too many connections open at once, then it may not be able to respond to new, legitimate connections. #1 Request Payload N/A Request POST https://<ip>:<port>/ #1 Host: <ip>:<port> #3 Accept: */* #4 Content-Type: application/x-www-form-urlencoded #1 Response Vulnerable to slow HTTP POST attack Connection with partial POST body remained open for: 312932 milliseconds [2] 150124 Clickjacking - Framable Page (10) Severity Confirmed Vulnerability - Level 3 Group Information Disclosure CVSS Base 6.4 CVSS Temporal5.8 Threat The web page can be framed. This means that clickjacking attacks against users are possible. #1 Request Payload N/A Request GET https://<ip>:<port>/ #1 Host: <ip>:<port> #3 Accept: */* #1 Response The URI was framed.

Severity Information Gathered - Level 1 Group Information Gathered Threat HTTP Strict Transport Security (HSTS) header found to be missing or misconfigured. HSTS header dictates to a conforming browser that the current and all subsequent connections (for a configurable amount of time) to the subject website should only be performed over a secure transport layer. Additionally, users are not permitted to bypass SSL/TLS certificate errors; preventing browser click-throughs in the event of expired or otherwise untrusted certificates.
