Technical details
Phoca Maps versions 5.0.0 through 6.0.2 are vulnerable to multiple stored Cross-Site Scripting (XSS) attacks (CWE-79). The vulnerability exists within the rendering logic for maps and icons, where user-supplied input is improperly neutralized before being stored and subsequently displayed to other users. An attacker can exploit this by submitting malicious JavaScript through map or icon configuration fields. When a site visitor or administrator views the affected map, the script executes in their browser context. This can lead to session hijacking, unauthorized administrative actions, or redirection to malicious sites.
