The 'www-data' user is a member of the 'nagios' group, which has write access to '/usr/local/nagioslogserver/scripts', while several scripts in this directory are owned by root and may be executed via sudo without a password. A local attacker running as 'www-data' can move one of these root-owned scripts to a backup name and create a replacement script with attacker-controlled content at the original path, then invoke it with sudo. This allows arbitrary commands to be executed with root privileges, providing full compromise of the underlying operating system."}],"metrics":{"cvssMetricV40":[{"source":"disclosure@vulncheck.com","type":"Secondary","cvssData":{"version":"4.0","vectorString":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","baseScore":8.5,"baseSeverity":"HIGH","attackVector":"LOCAL","attackComplexity":"LOW","attackRequirements":"NONE","privilegesRequired":"LOW","userInteraction":"NONE","vulnConfidentialityImpact":"HIGH","vulnIntegrityImpact":"HIGH","vulnAvailabilityImpact":"HIGH","subConfidentialityImpact":"NONE","subIntegrityImpact":"NONE","subAvailabilityImpact":"NONE","exploitMaturity":"NOT_DEFINED","confidentialityRequirement":"NOT_DEFINED","integrityRequirement":"NOT_DEFINED","availabilityRequirement":"NOT_DEFINED","modifiedAttackVector":"NOT_DEFINED","modifiedAttackComplexity":"NOT_DEFINED","modifiedAttackRequirements":"NOT_DEFINED","modifiedPrivilegesRequired":"NOT_DEFINED","modifiedUserInteraction":"NOT_DEFINED","modifiedVulnConfidentialityImpact":"NOT_DEFINED","modifiedVulnIntegrityImpact":"NOT_DEFINED","modifiedVulnAvailabilityImpact":"NOT_DEFINED","modifiedSubConfidentialityImpact":"NOT_DEFINED","modifiedSubIntegrityImpact":"NOT_DEFINED","modifiedSubAvailabilityImpact":"NOT_DEFINED","Safety":"NOT_DEFINED","Automatable":"NOT_DEFINED","Recovery":"NOT_DEFINED","valueDensity":"NOT_DEFINED","vulnerabilityResponseEffort":"NOT_DEFINED","providerUrgency":"NOT_DEFINED"}}],"cvssMetricV31":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","baseScore":7.8,"baseSeverity":"HIGH","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":1.8,"impactScore":5.9}]},"weaknesses":[{"source":"disclosure@vulncheck.com","type":"Secondary","description":[{"lang":"en","value":"CWE-732"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:nagios:log_server:*:*:*:*:*:*:*:*","versionEndExcluding":"2026","matchCriteriaId":"193F80CC-75B5-4F6B-8C44-ABB8ADC43C31"},{"vulnerable":true,"criteria":"cpe:2.3:a:nagios:log_server:2026:r1:*:*:*:*:*:*","matchCriteriaId":"B2FC4948-E93B-4F6F-83D5-17A39A5DDAAA"}]}]}],"references":[{"url":"https://theyhack.me/Rooting-Nagios-Log-Server/","source":"disclosure@vulncheck.com"},{"url":"https://www.nagios.com/changelog/nagios-log-server/nagios-log-server-2026r1-0-1/","source":"disclosure@vulncheck.com","tags":["Release Notes"]},{"url":"https://www.nagios.com/products/security/#log-server","source":"disclosure@vulncheck.com","tags":["Vendor Advisory"]},{"url":"https://www.vulncheck.com/advisories/nagios-log-server-local-privilege-escalation-via-writable-scripts-and-sudo-rules","source":"disclosure@vulncheck.com","tags":["Third Party Advisory"]}]}}]}
