EUVDB-ID: #VU31088
Risk: Low
CVSSv3.1: 5.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-11537
CWE-ID:
CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data when processing data passed via /upload/file.php, /upload/scp/users.php?do=import-users, and /upload/scp/ajax.php/users/import if an agent manager user uploads a crafted .csv file to the User Importer, because file contents can appear in an error message. The XSS can lead to local file inclusion. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in 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.
MitigationUpdate to version 1.12.
