Do any TACACS+-speaking solutions (current or legacy) have a basis on the Shrubbery fork of tac_plus? There's an unauth'd RCE in just about all versions (no CVE yet): https://github.com/elttam/publications/blob/master/writeups/elttam-tac_plus_rce_fmtstring_advisory.txt Some threat-intel folks are collecting what we know here (disclosure: my post, but it's volunteer), so if anyone replies (here or on the side), I'll update here: https://ifin.network/t/cve-pending-pre-auth-format-string-bug-in-tac-plus-shrubbery-networks/859/1 I'm interested in legacy / EOL platform info as well -- like some are still in the field. And upstream updates are sporadic (until this year when .31 was released, there hadn't been a release since .28 in 2015), so embedding could go way back. I don't have vendor access anymore, so any feedback / corrections appreciated. -- Royce Williams Tech Solvency _______________________________________________ NANOG mailing list https://lists.nanog.org/archives/list/nanog () lists nanog org/message/AY32ZYSY7ZRWSHNWZF74TNNHVZNYOY5I/
