An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. A successful exploit could allow the attacker to write files to the underlying operating system that could be used later to elevate to root.\r\nNote: Cisco has assigned this security advisory a Security Impact Rating (SIR) of Critical rather than High as the score indicates. The reason is that exploitation of this vulnerability could result in an attacker elevating privileges to root.\r\nNote: To exploit this vulnerability, the WebDialer service must be enabled. WebDialer is disabled by default.","A vulnerability in Cisco Unified Communications Manager (Unified CM) and Cisco Unified Communications Manager Session Management Edition (Unified CM SME) cou...","2026-06-03T18:16:20.16","2026-10-07T19:17:37.003",8.6,"CVSS:3.1\u002FAV:N\u002FAC:L\u002FPR:N\u002FUI:N\u002FS:C\u002FC:N\u002FI:H\u002FA:N",{"CVSSMetricV31":15,"CVSSMetricV30":29,"CVSSMetricV2":30,"CVSSMetricV40":31},[16],{"Source":17,"Type":18,"CVSSData":19,"ExploitabilityScore":27,"ImpactScore":28},"psirt@cisco.com","Secondary",{"Version":20,"VectorString":13,"AttackVector":21,"AttackComplexity":22,"PrivilegesRequired":23,"UserInteraction":23,"Scope":24,"ConfidentialityImpact":23,"IntegrityImpact":25,"AvailabilityImpact":23,"BaseScore":12,"BaseSeverity":25,"ExploitCodeMaturity":26,"RemediationLevel":26,"ReportConfidence":26,"TemporalScore":26,"TemporalSeverity":26,"ConfidentialityRequirement":26,"IntegrityRequirement":26,"AvailabilityRequirement":26,"ModifiedAttackVector":26,"ModifiedAttackComplexity":26,"ModifiedPrivilegesRequired":26,"ModifiedUserInteraction":26,"ModifiedScope":26,"ModifiedConfidentialityImpact":26,"ModifiedIntegrityImpact":26,"ModifiedAvailabilityImpact":26,"EnvironmentalScore":26,"EnvironmentalSeverity":26},"3.1","NETWORK","LOW","NONE","CHANGED","HIGH",null,3.9,4,[],[],[],0.882,[32,32,32,32,32,32,32],"High",[36],{"vendor":37,"product":38,"version":39,"criteria":40,"vulnerable":4},"cisco","unified_communications_manager","*","cpe:2.3:a:cisco:unified_communications_manager:*:*:*:*:-:*:*:*",1,[43,48,54],{"url":44,"source":45,"tags":46},"https:\u002F\u002Fsec.cloudapps.cisco.com\u002Fsecurity\u002Fcenter\u002Fcontent\u002FCiscoSecurityAdvisory\u002Fcisco-sa-cucm-ssrf-cXPnHcW","Cisco",[47],"Vendor Advisory",{"url":49,"source":50,"tags":51},"https:\u002F\u002Fdenizhalil.com\u002F2026\u002F06\u002F12\u002Fcve-2026-20230-cisco-unified-cm-ssrf\u002F","Denizhalil",[52,53],"Exploit","Third Party Advisory",{"url":55,"source":56,"tags":57},"https:\u002F\u002Fwww.cisa.gov\u002Fknown-exploited-vulnerabilities-catalog?field_cve=CVE-2026-20230","CISA",[58],"US Government Resource",3,[61],{"id":62,"name":63,"description":64,"extendedDescription":65,"status":66,"abstraction":67,"structure":68},"CWE-918","Server-Side Request Forgery (SSRF)","The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.","By providing URLs to unexpected hosts or ports, attackers can make it appear that the server is sending the request, possibly bypassing access controls such as firewalls that prevent the attackers from accessing the URLs directly.
