{“lastseen”:””,”description”:”ACE vulnerability in conditional configuration file processing by QOS.CH logback-core up to and including version 1.5.18 in Java applications, allows an attacker to execute arbitrary code by compromising an existing logback configuration file or by injecting an environment variable before program execution.\\n\\n\\n\\nA successful attack requires the presence of Janino library and Spring Framework to be present on the user’s class path. In addition, the attacker must\u00a0 have write access to a \\nconfiguration file. Alternatively, the attacker could inject a malicious \\nenvironment variable pointing to a malicious configuration file. In both \\ncases, the attack requires existing privilege.”,”published”:”2025-10-01T07:26:12.567Z”,”modified”:”2025-10-01T07:26:12.567Z”,”type”:”cve”,”title”:”Conditional processing of logback.xml configuration file, in conjuction with Spring Framework and Janino”,”source”:”NCSC.ch”,”references”:”https:\/\/logback.qos.ch\/news.html#1.5.19″,”id”:”CVE-2025-11226″,”bulletinFamily”:””,”cwe”:[“CWE-20″],”cvelist”:null,”sourceData”:”QOS.CH Sarl Logback-core 0.9.20″,”sourceHref”:””,”cvss”:{“score”:5.9,”severity”:”MEDIUM”,”vector”:”CVSS:4.0\/AV:L\/AC:L\/AT:P\/PR:H\/UI:P\/VC:H\/VI:L\/VA:L\/SC:H\/SI:L\/SA:L\/AU:N\/RE:M\/U:Green”,”version”:”4.0″},”cvss2″:{},”cvss3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””,”cvssV3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””}},”href”:””,”category_name”:”CVE”,”post_link”:””,”product”:”Logback-core”,”version”:”0.9.20″,”vendor”:”QOS.CH Sarl”,”ai_description”:””,”ai_severity”:””,”ai_vendor”:””,”ai_product”:””,”ai_version”:””,”ai_score”:0}<\/p>\n","protected":false},"excerpt":{"rendered":"
