This security bulletin contains information about 2 vulnerabilities.
EUVDB-ID: #VU11537
Risk: Low
CVSSv3.1: 3.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-17742
CWE-ID:
CWE-113 - Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform HTTP response splitting attack.
The weakness exists due to improper handling of HTTP requests. If a script accepts an external input and outputs it without modification as a part of HTTP responses, a remote attacker can use newline characters to trick the victim that the HTTP response header is stopped at there and inject fake HTTP responses after the newline characters to show malicious contents to the victim.
