Noroxi assessment

Priority: Monitor (action score 21/100)

  • 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: 0.22% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No special conditions are required; it is repeatable.
  • Fixed version: OpenIdentityPlatform OpenAM 16.1.4.

Low priority for now. Upgrade to OpenIdentityPlatform OpenAM 16.1.4 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

OpenAM before 16.1.4 contains an open redirect and cross-site scripting vulnerability that allows remote attackers to control post-login and logout destinations via the goto and gotoOnFail parameters. Attackers can craft OpenAM login or logout links that redirect victims to phishing sites or run script in the XUI to steal session cookies.

Limit the impact of XSS

This is a cross-site scripting (XSS) vulnerability. A well-configured Content-Security-Policy doesn't fix it, but greatly reduces its impact. Check your site's CSP and other security headers for free.
