{"apiVersion":"1.0","identifier":"CVE-2026-52817","description":"Linuxfabrik Monitoring Plugins provides monitoring plugins for Icinga, Nagios, and related systems. Prior to version 5.1.0, the shipped assets/sudoers/Debian.sudoers policy allowed the nagios or icinga account to execute /usr/bin/apt-get as root without restricting its arguments. An attacker who already controls that monitoring account can supply the APT::Update::Pre-Invoke option to execute an arbitrary command while apt-get runs with root privileges, resulting in a root shell and complete compromise of the host. The vulnerable rule supports the check-plugins/deb-updates/deb-updates plugin, but it authorized arbitrary apt-get argument sequences rather than only the required apt-get update --quiet 2 command. This issue is fixed in version 5.1.0.","publishedAt":"2026-08-18T21:16:34","lastModifiedAt":"2026-08-19T19:17:18","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-52817","cvssScore":7,"cvssVector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/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","epssProbability":0.00188,"riskScore":0.71,"affectedProduct":"Linuxfabrik Monitoring Plugins","affectedVersions":"<5.1.0","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-52817","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-52817","en":"https://www.redsauce.net/en/cves/CVE-2026-52817","fr":"https://www.redsauce.net/fr/cves/CVE-2026-52817","pt":"https://www.redsauce.net/pt/cves/CVE-2026-52817","de":"https://www.redsauce.net/de/cves/CVE-2026-52817","sk":"https://www.redsauce.net/sk/cves/CVE-2026-52817","el":"https://www.redsauce.net/el/cves/CVE-2026-52817"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-52817"}}
