Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Cross-site scripting
EUVDB-ID: #VU41037
Risk: Low
CVSSv3.1: 5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N/E:P/RL:U/RC:C]

CWE-ID:
CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Exploit availability: Yes
DescriptionVulnerability allows a remote attacker to perform XSS attacks.
The vulnerability is caused by an input validation error in MyBB (aka MyBulletinBoard) 1.8.x before 1.8.2 when processing the (1) type parameter to report.php, (2) signature parameter in a do_editsig action to usercp.php, or (3) title parameter in the style-templates module in an edit_template action or (4) file parameter in the config-languages module in an edit action to admin/index.php. A remote attacker can trick the victim to follow a 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.
