Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Photo Station is installed on the QNAP deviceAccess the QNAP App Center or QTS desktop and verify that Photo Station application appears in the installed applications list. Alternatively, attempt to access the Photo Station web interface by navigating to http(s)://[NAS_IP]/photo/Affected if Photo Station is not listed as an installed application or the Photo Station web interface is not accessible, the system is not affected by this vulnerability.
-
Identify the installed Photo Station versionLog into the Photo Station web interface as an administrator. Navigate to the Settings or About section, where the application version is typically displayed. Alternatively, check the QNAP App Center which shows the installed version of Photo Station.Affected if The detected version is any version prior to 6.0.11 (for example, 6.0.10, 5.x, or earlier), the system is vulnerable to this XSS flaw.
-
Verify the Photo Station web interface is network-accessibleAttempt to reach the Photo Station URL (typically /photo/ or /photo/index.php) from a client on the network. Confirm the service is listening and responding. Check if the QNAP device has port forwarding or firewall rules that allow external access to Photo Station.Affected if The Photo Station web interface is exposed to untrusted networks (such as the internet), the XSS vulnerability can be exploited by remote attackers without authentication.
-
Compare installed version against affected rangeDocument the exact Photo Station version number found in step 2 and compare it to the affected range: versions less than 6.0.11 are vulnerable.Affected if The installed version is below 6.0.11 and Photo Station is accessible as described above, the environment is affected by CVE-2020-2502.
A system is affected if Photo Station is installed and running with a version lower than 6.0.11, with the web interface accessible to potential attackers.
