Summary
Stored Cross-Site Scripting (XSS) vulnerability allows attackers to inject malicious scripts into web applications, which can then be executed in the context of other users' browsers. This can lead to unauthorized access to sensitive information, session hijacking, and spreading of malware, impacting user data privacy and application integrity.
Details
A user with rights to modificate the service (e.g. kuiperUser role) can inject XSS Payload into Connection Configuration key Name (confKey) parameter. Then, after any user with access to this service (e.g. admin) will try to delete this key, a payload will act in victim's browser.
PoC
- Authorize as a user with rights to modificate the service (e.g. kuiperUser role).
- Create a service or go to the existing one and access the Configuration > Connection page:
- Open any existing Connection and press on
Add configuration key:
- Set any name and Address, then intercept the request and add the following payload to the
confKeyparameter:123%3Cimg%20src=1%20onerror%3dalert%281%29%3E:
- A new configuration key then will be set:
- (Optional) You can authorize another user with access to this service. For nexe steps I will use admin user
- After we push on delete button (trash icon) opposite the created connection, the payload will work:

Reported by Alexey Kosmachev, Lead Pentester from Bi.Zone
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker needs basic access or low-level privileges. The attacker needs the user to perform some action, like clicking a link. The impact is confined to the system where the vulnerability exists. There is a high impact on the confidentiality of the information. There is a low impact on the integrity of the data.
Exploitation attempts have been detected. Elevated vigilance and prompt remediation are advised.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
