Reflected XSS in Flexostudio Flexo Counter 1.0001 and earlier allows remote attackers to execute script in a victim's browser via a crafted request. Public advisories do not identify the vulnerable parameter or code locus, disclosing only that request input is reflected without adequate neutralization during page generation. Exploitation requires a victim to open the crafted request, after which script runs in the affected site's browser context and can read or alter accessible page data.
