Prior to 0.18.1, Moquette does not limit the depth of topic names and topic filters before processing them through recursive CTrie insertion and matching operations. A remote client can publish or subscribe with a deeply nested topic, causing a StackOverflowError that disrupts session processing and can deny service to broker clients. This issue is fixed in version 0.18.1.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-674"],"vendors":["moquette"],"products":["moquette"],"references":[{"url":"https://github.com/moquette-io/moquette/commit/ca17e0be19e86d5e291f4532dfdc94616c8e0049","tags":["Patch"]},{"url":"https://github.com/moquette-io/moquette/releases/tag/v0.18.1","tags":["Release Notes"]},{"url":"https://github.com/moquette-io/moquette/security/advisories/GHSA-5f42-97gr-vfhq","tags":["Exploit","Mitigation","Vendor Advisory"]},{"url":"https://github.com/moquette-io/moquette/security/advisories/GHSA-5f42-97gr-vfhq","tags":["Exploit","Mitigation","Vendor Advisory"]}],"exploitRefs":[{"url":"https://github.com/moquette-io/moquette/commit/ca17e0be19e86d5e291f4532dfdc94616c8e0049","tags":["Patch"]},{"url":"https://github.com/moquette-io/moquette/releases/tag/v0.18.1","tags":["Release Notes"]},{"url":"https://github.com/moquette-io/moquette/security/advisories/GHSA-5f42-97gr-vfhq","tags":["Exploit","Mitigation","Vendor Advisory"]},{"url":"https://github.com/moquette-io/moquette/security/advisories/GHSA-5f42-97gr-vfhq","tags":["Exploit","Mitigation","Vendor Advisory"]}],"hasPoc":true,"ai":null}
