An API-level vulnerability in Nagios Log Server 2024R1.3.1 allows any user with a valid API token to retrieve a full list of user accounts along with their plaintext API keys, including administrator credentials. This flaw enables user enumeration, privilege escalation, and full system compromise via unauthorized use of exposed tokens.
A stored XSS vulnerability in Nagios Log Server 2024R1.3.1 allows a low-privileged user to inject malicious JavaScript into the 'email' field of their profile. When an administrator views the audit logs, the script executes, resulting in privilege escalation via unauthorized admin account creation. The vulnerability can be chained to achieve remote code execution (RCE) in certain configurations.
A stored cross-site scripting (XSS) in Nagios Log Server 2.1.7 can result in an attacker performing malicious actions to users who open a maliciously crafted link or third-party web page.
Nagios Log Server is a popular Centralized Log Management, Monitoring, and Analysis software that allows organizations to view, sort, and configure logs. Version 2.1.6 of the application was found to be vulnerable to Stored XSS. An attacker (in this case, an authenticated regular user) can use this vulnerability to execute malicious JavaScript aimed to steal cookies, redirect users, perform arbitrary actions on the victim’s (in this case, an admin’s) behalf, logging their keystroke and more. The 'Full Name' and 'Username' fields in the /profile page or /admin/users/create page are vulnerable to Stored XSS. Once a payload is saved in one of these fields, navigate to the Alerting page (/alerts) and create a new alert and select Email Users as the Notification Method. As the user list is shown, it can be seen that the payload gets executed.
