Access to privileged operations on the maintenance port TELNET interface (23/TCP) on M-series and SIS (CSLS/LSNB/LSNG) nodes is controlled by means of utility passwords. These passwords are generated using a deterministic, insecure algorithm using a single seed value composed of a day/hour/minute timestamp with less than 16 bits of entropy. The seed value is fed through a lookup table and a series of permutation operations resulting in three different four-character passwords corresponding to different privilege levels. An attacker can easily reconstruct these passwords and thus gain access to privileged maintenance operations. NOTE: this is different from CVE-2014-2350."}]}, "problemtype": {"problemtype_data": [{"description": []}]}, "data_version": "4.0", "CVE_data_meta": {"ID": "CVE-2022-29965", "ASSIGNER": "cve@mitre.org"}}, "impact": {}, "publishedDate": "2022-07-26T22:15Z", "configurations": {"nodes": [], "CVE_data_version": "4.0"}, "lastModifiedDate": "2022-07-27T07:24Z"}
