VAR-200205-0127

Vulnerability from variot - Updated: 2025-04-03 22:24

tac_plus Tacacs+ daemon F4.0.4.alpha, originally maintained by Cisco, creates files from the accounting directive with world-readable and writable permissions, which allows local users to access and modify sensitive files. tac_plus is an open source, freely available implementation of a TACACS+ server. It was originally written by Cisco. tac_plus creates accounting files insecurely. When tac_plus is started, it creates the file specified in the "account file =" configuration parameter with world-writable permissions. This could allow a local user to alter the contents, or entirely remove the accounting file. There are vulnerabilities in tac_plus when creating files, and local attackers can arbitrarily manipulate the files created by tac_plus
