Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
EUVDB-ID: #VU1184
Risk: Low
CVSSv3.1: 3.4 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N/E:P/RL:O/RC:C]
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.
MitigationUpdate the affected packages.
