Denial of service in the Zabbix web frontend allows an authenticated user - including the built-in Guest account when Guest access is still enabled - to drive disproportionate CPU load on the webserver by sending specially crafted parameters to /imgstore.php. The vulnerable image-serving endpoint amplifies trivial requests into heavy server-side processing, so sustained requests can exhaust frontend CPU and impair availability of the Zabbix UI for legitimate operators. Affected builds span Zabbix 6.0.0-6.0.41, 7.0.0-7.0.18, 7.2.0-7.2.12 and 7.4.0-7.4.2; a vendor patch is available, EPSS is low (0.05%, 16th percentile), and no public exploit code or confirmed active exploitation was identified at time of analysis.
Arbitrary file read in Zabbix Frontend 7.4.0 through 7.4.2 allows an authenticated Super Admin to exploit the oauth.authorize action to read files from the web server, resulting in confidentiality loss. The requirement for the highest-privilege role makes this primarily an insider-abuse or post-compromise vulnerability, not an external attack vector. EPSS is very low (0.03%) and no public exploit has been identified; the vendor has released patches.
The website configured in the URL widget will receive a session cookie when testing or executing scheduled reports. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
A security defect was identified in Foundry Frontend that enabled users to potentially conduct DOM XSS attacks if Foundry's CSP were to be bypassed. Rated medium severity (CVSS 6.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
Reflected XSS attacks, occur when a malicious script is reflected off a web application to the victim's browser. Rated medium severity (CVSS 6.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity.
URL validation scheme receives input from a user and then parses it to identify its various components. Rated medium severity (CVSS 5.4), this vulnerability is remotely exploitable, low attack complexity.
Reflected XSS attacks, also known as non-persistent attacks, occur when a malicious script is reflected off a web application to the victim's browser. Rated medium severity (CVSS 6.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity.
Stored or persistent cross-site scripting (XSS) is a type of XSS where the attacker first sends the payload to the web application, then the application saves the payload (e.g., in a database or. Rated medium severity (CVSS 5.4), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
Zabbix Frontend provides a feature that allows admins to maintain the installation and ensure that only certain IP addresses can access it. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
An authenticated user can create a link with reflected Javascript code inside it for graphs’ page and send it to other users. Rated medium severity (CVSS 4.4), this vulnerability is remotely exploitable. This Cross-Site Scripting (XSS) vulnerability could allow attackers to inject malicious scripts into web pages viewed by other users.
