Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Cross-site scripting
EUVDB-ID: #VU7287
Risk: Low
CVSSv3.1: 5.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:P/RL:O/RC:C]
CVE-ID: CVE-2017-9313
CWE-ID:
CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Exploit availability: No
DescriptionVulnerability allows a remote attacker to perform Cross-site scripting attacks.
An input validation error exists when processing user-supplied input passed via "sec" HTTP GET parameter to "/man/view_man.cgi" script. A remote authenticated attacker can trick the victim to follow a specially specially crafted link and execute arbitrary HTML and script code in victim's browser in security context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
Exploitation example:
https://[host]:10000/man/view_man.cgi?page=foo&sec=<script>alert('xss')</script>
