An attacker could exploit this vulnerability by uploading a crafted file to the web UI. A successful exploit could allow the attacker to upload arbitrary files to a vulnerable system and execute them, gaining access to the underlying operating system. To exploit this vulnerability, the attacker must have valid administrative credentials.\n\n## Affected\n\n- `unified_contact_center_express 10.5(1)SU1`\n- `unified_contact_center_express 10.6(1)`\n- `unified_contact_center_express 11.6(1)`\n- `unified_contact_center_express 10.6(1)SU1`\n- `unified_contact_center_express 10.6(1)SU3`\n- `unified_contact_center_express 11.6(2)`\n- `unified_contact_center_express 12.0(1)`\n- `unified_contact_center_express 11.0(1)SU1`\n- `unified_contact_center_express 11.5(1)SU1`\n- `unified_contact_center_express 10.5(1)`\n- `unified_contact_center_express 12.5(1)`\n- `unified_contact_center_express 12.5(1)SU1`\n- `unified_contact_center_express 12.5(1)SU2`\n- `unified_contact_center_express 12.5(1)SU3`\n- `unified_contact_center_express 12.5(1)_SU03_ES01`\n- `unified_contact_center_express 12.5(1)_SU03_ES02`\n- `unified_contact_center_express 12.5(1)_SU02_ES03`\n- `unified_contact_center_express 12.5(1)_SU02_ES04`\n- `unified_contact_center_express 12.5(1)_SU02_ES02`\n- `unified_contact_center_express 12.5(1)_SU01_ES02`\n- `unified_contact_center_express 12.5(1)_SU01_ES03`\n- `unified_contact_center_express 12.5(1)_SU02_ES01`\n- `unified_contact_center_express 11.6(2)ES07`\n- `unified_contact_center_express 11.6(2)ES08`\n- `unified_contact_center_express 12.5(1)_SU01_ES01`\n- `unified_contact_center_express 12.0(1)ES04`\n- `unified_contact_center_express 12.5(1)ES02`\n- `unified_contact_center_express 12.5(1)ES03`\n- `unified_contact_center_express 11.6(2)ES06`\n- `unified_contact_center_express 12.5(1)ES01`\n- `unified_contact_center_express 12.0(1)ES03`\n- `unified_contact_center_express 12.0(1)ES01`\n- `unified_contact_center_express 11.6(2)ES05`\n- `unified_contact_center_express 12.0(1)ES02`\n- `unified_contact_center_express 11.6(2)ES04`\n- `unified_contact_center_express 11.6(2)ES03`\n- `unified_contact_center_express 11.6(2)ES02`\n- `unified_contact_center_express 11.6(2)ES01`\n- `unified_contact_center_express 10.6(1)SU3ES03`\n- `unified_contact_center_express 11.0(1)SU1ES03`\n- `unified_contact_center_express 10.6(1)SU3ES01`\n- `unified_contact_center_express 10.5(1)SU1ES10`\n- `unified_contact_center_express 11.5(1)SU1ES03`\n- `unified_contact_center_express 11.6(1)ES02`\n- `unified_contact_center_express 11.5(1)ES01`\n- `unified_contact_center_express 10.6(1)SU2`\n- `unified_contact_center_express 10.6(1)SU2ES04`\n- `unified_contact_center_express 11.6(1)ES01`\n- `unified_contact_center_express 10.6(1)SU3ES02`\n- `unified_contact_center_express 11.5(1)SU1ES02`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":36,"depthScoreParts":{"impact":35.8,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
