Affected releases enforce a password policy of at least 12 characters including upper-case, lower-case, numeric and special characters, so practical exploitation requires a reused or predictable password rather than exhaustive guessing. The WAMP-CRA authentication path is removed in 1.11.0.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":6.3,"severity":"medium","source":"CNA: Zenitel","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N","version":"4.0"},{"score":6.3,"severity":"medium","source":"NVD: cf9c5165-6fe5-4ec0-b5f1-404f1df30a4e","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/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","version":"4.0"}],"modifiedAt":1794608239333,"publishedAt":1794584423944,"references":[{"source":"CNA: Zenitel","tags":[],"url":"https://www.zenitel.com/sites/default/files/2026-11/A100K12404-Zenitel-Security-Advisory.pdf"},{"source":"cf9c5165-6fe5-4ec0-b5f1-404f1df30a4e","tags":[],"url":"https://www.zenitel.com/sites/default/files/2026-11/A100K12404-Zenitel-Security-Advisory.pdf"}],"remediation":[{"kind":"fix","source":"CNA: Zenitel","text":"Upgrade to version 1.11.0, which removes the WAMP-CRA authentication path"}],"revision":"c6824d0a8acdb3dd41dc3e41b24e76a0ed38afe3169ae71d3939ebcbed6f25b7","sources":[{"modifiedAt":1794606382488,"name":"CNA: Zenitel","retrievedAt":1794607711676,"url":"https://www.cve.org/CVERecord?id=CVE-2026-105622"},{"modifiedAt":1794608239333,"name":"NVD","retrievedAt":1794615544115,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-105622"}],"ssvc":{"assessedAt":1794606374050,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Zenitel Connect missing lockout and rate limiting on the WAMP-CRA authentication channel","updatedAt":1794615544115}
