MediumCVSS 5.3 · v3.1—No exploit Fix available

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: 1.8% (FIRST EPSS); higher than 79.4% 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. Special conditions such as timing or configuration are required.
  • Fixed version: novnc (Red Hat:rhev_manager:4.4:el8) 0:1.1.0-1.el8ost; ovirt-engine (Red Hat:rhev_manager:4.4:el8) 0:4.4.1.8-0.7.el8ev; ovirt-engine-api-explorer (Red Hat:rhev_manager:4.4:el8) 0:0.0.6-1.el8ev.

Low priority for now. Upgrade to novnc (Red Hat:rhev_manager:4.4:el8) 0:1.1.0-1.el8ost; ovirt-engine (Red Hat:rhev_manager:4.4:el8) 0:4.4.1.8-0.7.el8ev; ovirt-engine-api-explorer (Red Hat:rhev_manager:4.4:el8) 0:0.0.6-1.el8ev or later.

Primary sources: NVD · CVE.org · FIRST EPSS

An Open redirect vulnerability was found in ovirt-engine versions 4.4 and earlier, where it allows remote attackers to redirect users to arbitrary web sites and attempt phishing attacks. Once the target has opened the malicious URL in their browser, the critical part of the URL is no longer visible. The highest threat from this vulnerability is on confidentiality.
