2) Improper input validation
EUVDB-ID: #VU1184
Risk: Low
CVSSv4.0: 2.9 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:P/U:Clear]
CVE-ID: CVE-2016-6816
CWE-ID:
CWE-200 - Information exposure
Exploit availability: Yes
Description
The vulnerability allows a remote attacker to manipulate HTTP responses.
The vulnerability exists due to incorrect parsing of HTTP requests. A remote attacker can send a specially crafted HTTP request containing specially crafted characters and perform XSS attacks, manipulate HTTP responses or obtain potentially sensitive data, belonging to other sessions.
Successful exploitation of the vulnerability may allow an attacker to gain access to potentially sensitive information, but requires presence of a proxy server, which does not block injected characters.

3) Denial of service
EUVDB-ID: #VU1185
Risk: Medium
CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2016-6817
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
Description
The vulnerability allows a remote attacker to perform a DoS attack.
The vulnerability exists due to boundary error when parsing HTTP/2 headers. A remote attacker can send a specially crafted HTTP/2 header longer than available buffer and trigger infinite loop.
Successful exploitation of the vulnerability may result in denial of service.
