When chained with CVE-2023-20198, the attacker can leverage the new local user to elevate privilege to root and write the implant to the file system. Cisco identified CVE-2023-20273 as the vulnerability exploited to deploy the implant. CVE-2021-1435, previously associated with the exploitation events, is no longer believed to be related to this activity. | Required action: Verify that instances of Cisco IOS XE Web UI are in compliance with BOD 23-02 and apply mitigations per vendor instructions. For affected products (Cisco IOS XE Web UI exposed to the internet or to untrusted networks), follow vendor instructions to determine if a system may have been compromised and immediately report positive findings to CISA. | Due date: 2023-10-27 | Known ransomware campaign use (KEV): Unknown | Notes (KEV): https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-webui-privesc-j22SaA4z;  https://nvd.nist.gov/vuln/detail/CVE-2023-20273"}, "evidence": [{"type": "vendor_report", "source": "cisa-kev", "signal": "successful_exploitation", "confidence": 0.8, "details": {"cwes": ["CWE-78"], "feed": "CISA Known Exploited Vulnerabilities Catalog", "product": "Cisco IOS XE Web UI", "due_date": "2023-10-27", "date_added": "2023-10-23", "vendorProject": "Cisco", "vulnerabilityName": "Cisco IOS XE Web UI Command Injection Vulnerability", "knownRansomwareCampaignUse": "Unknown"}}], "references": [{"id": "CVE-2023-20273", "url": "https://www.cisa.gov/known-exploited-vulnerabilities-catalog?search_api_fulltext=CVE-2023-20273"}]}
