Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
1) Overly permissive cross-domain whitelist
EUVDB-ID: #VU84369
Risk: Medium
CVSSv3.1: 6.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-46281
CWE-ID:
CWE-942 - Overly Permissive Cross-domain Whitelist
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass the CORS protection mechanism.
The vulnerability exists due to incorrect processing of the "Origin" HTTP header that is supplied within HTTP request. A remote attacker can supply arbitrary value via the "Origin" HTTP header, bypass implemented CORS protection mechanism and perform cross-site scripting attacks against the vulnerable application.

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
How the attacker can exploit this vulnerability?
The attacker would have to send a specially crafted request to the affected application in order to exploit this vulnerability.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Cross-site scripting
EUVDB-ID: #VU84371
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-2023-46282
CWE-ID:
CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Exploit availability: No
DescriptionThe disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data in the web interface. 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.
