Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.63% (FIRST EPSS); higher than 50.5% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: Unknown Salon booking system 9.6.3.

Low priority for now. Upgrade to Unknown Salon booking system 9.6.3 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

The Salon booking system WordPress plugin before 9.6.3 does not properly sanitize and escape the 'Mobile Phone' field when booking an appointment, allowing customers to conduct Stored Cross-Site Scripting attacks. The payload gets triggered when an admin visits the 'Customers' page and the malicious script is executed in the admin context.
