Noroxi assessment

Priority: Monitor (action score 17/100)

  • 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: 1.1% (FIRST EPSS); higher than 68.2% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: chromium-browser (Debian:8) 50.0.2661.75-1~deb8u1; chromium-browser (Red Hat:rhel_extras:6) 0:50.0.2661.75-1.el6; chromium-browser-debuginfo (Red Hat:rhel_extras:6) 0:50.0.2661.75-1.el6.

Low priority for now. Upgrade to chromium-browser (Debian:8) 50.0.2661.75-1~deb8u1; chromium-browser (Red Hat:rhel_extras:6) 0:50.0.2661.75-1.el6; chromium-browser-debuginfo (Red Hat:rhel_extras:6) 0:50.0.2661.75-1.el6 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The Extensions subsystem in Google Chrome before 50.0.2661.75 incorrectly relies on GetOrigin method calls for origin comparisons, which allows remote attackers to bypass the Same Origin Policy and obtain sensitive information via a crafted extension.
