Subject Apache flink 1.7.2 security issues
Date Sun, 11 Aug 2019 16:20:44 GMT
Hello,

We are using Apache Flink 1.7.2 version. During our security scans following issues are reported
by our scan tool. Please let us know your comments on these issues.

[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)

[4] 150081 X-Frame-Options header is not set (10)
Severity Potential Vulnerability - Level 1
Group Information Disclosure
CVSS Base 5 CVSS Temporal4.1

Threat
The X-Frame-Options header is not set in the HTTP response, which may lead to a possible framing
of the page. An attacker can trick users into clicking on a
malicious link by framing the original page and showing a layer on top of it with legitimate-looking
buttons.

#1 Request
Payload N/A
Request GET https://<ip>:<port>/
#1 Host: <ip>:<port>
#3 Accept: */*

#1 Response
The response for this request either did not have an "X-FRAME-OPTIONS" header present or was
not set to DENY or SAMEORIGIN

[7] 150135 HTTP Strict Transport Security (HSTS) header missing/misconfigured.
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.

Strict Transport Security header missing for
https://<ip>:<port>/
