An updated version of Cisco's TACACS+ server.
A vulnerabilitiy has been discovered in TACACS+. Please review the CVE identifier referenced below for details.
A lack of input validation exists in tac_plus which, when pre or post auth commands are enabled, allows an attacker who can control the username, rem-addr, or NAC address sent to tac_plus to inject shell commands and gain remote code execution on the tac_plus server.
There is no known workaround at this time.
Gentoo has discontinued support for TACACS+. We recommend that users unmerge it:
# emerge --ask --depclean "net-nds/tac_plus"
